AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION REPORT MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING INTRODUCTION The Amaravati Government Complex, as the initial seed development of Amaravati, will set a standard for the remainder of the city. In the context of an unprecedented and highly symbolic endeavor, this project must answer to the highest of aspirations of Andra Pradesh and of 21st Century India as a whole. The fundamental basis of the Master Plan is that Capital City - located at the center of Amaravati - should unite, rather than divide the city; it must draw people to it, become a center of activity, a true “people’s capital”. It should offer a series of places, plazas, and buildings that connect the site to the Riverside and the city . It should offer a variety of amenities to supplement Government functions and catalyze urban life. What are the core values that will define this new city and make it a place of gathering? From the brief and through our explorations, we summarize as follows: - The development must be smart, green, and sustainable at all scales -Ecological design principles at macro-scale -Sustainable design principles at micro-scale - low tech passive design -Resilient design at urban scale - maintaining a safe environment during disasters -Sensitivity to long term growth - a landscape designed to evolve with the city UNITING AMARAVATI - The development must be democratic, highly public, and vibrant -Work environment balanced by daily necessities and amenities. -Home environment independent from work, but still close by. -Both work and home supplemented by culture for a balanced life. -Security as a key to public life and vibrance - “invisible security” - The development must exhibit “formality,” not “monumentality” -the “image and aura of democratic governance” (from Jury comments) -symbolic weight as new capital symbol -modern and functional, but respecting traditions -a landmark with a memorable skyline This document is organized in three sections, corresponding to these major themes - all of which weave together to create the final vision for Amaravati Government Complex: -Master Planning: establishing a framework for human-scaled, ecological development (including building allocation, infrastructure, transportation, and programming) - for a vibrant, secure, and functional urban complex. CATALYZING URBAN LIFE AND CONNECTIONS -Landscape Planning: establishing landscape planning and details that integrate the built landscape into a cohesive, sustainable whole - connecting the complex to the surrounding city and eco-systems. -Architectural Planning: establishing an architectural language appropriate for 21st century India’s evolving democracy and populace - creating comfortable and functional work environments that support this vision. AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 01 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING I - MASTER PLANNING APPROACH MASTER PLANNING: PRECEDENTS In studying examples from around the world, we note that the framework of the Amaravati site has similarities in scale to iconic developments across the world. As such, these developments can be studied to glean both positive and negative aspects and better shape the planning at Amaravati. - The Washington DC Capital Mall has developed based on the McMillan plan from 1901; buildings and monuments continue to be added today. Its highly symmetrical and axial nature can be seen as overly formal, but its programming - a series of public museums and event spaces well loved by both residents and tourists - offers a good lesson for Amaravati. These public programs give the Mall a life and energy that would otherwise be missing. - The New Delhi government complex was inaugurated in 1931. It has a similar sense of grandeur and axiality as Washington DC. Though it can feel alienating and overly monumental, its sense of order offers a unique contrast to its surroundings. It represents a welcome moment of long vistas and greenery within the more dense surroundings of Delhi proper. - The Brasilia government complex, inaugurated in 1960, remains over scaled and lacking a sense of urbanity and vitality. It does, however, offer an iconic, contemporary look, fitting for a forward looking government complex, and avoiding reference to past building styles and technologies. Amaravati Government Complex site: from south to north, three 1 kilometer by 1 kilometer squares, with an additional irregularly shaped parcel at the north (bisected by the Bund Road and facing the Krishna River). Distinguishing Amaravati from these and other examples will be its unique site - its relationship to water (the Krishna River and its tributaries) as well as its connections to the surrounding landscape, mountains, and fertile agricultural soils. Understanding and mobilizing this site potential via landscape therefore becomes the first step in our development of the overall Master Plan. WASHINGTON DC, USA - 1901 NEW DELHI, INDIA - 1931 BRASILIA, BRAZIL - 1960 AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 02 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING MASTER PLANNING: ECOLOGICAL CONSIDERATIONS The two sketches to the left are early studies of the Government Complex site in relation to its larger context. The top sketch shows the site in relation to nearby mountains and waterways. The bottom sketch shows the immediate site in relation to existing villages, agricultural developments, and the waterways supplying them. Two distinct grid patterns exist on the site: 1. Derived from the N-S-E-W cardinal directions and the mountains / forest reserves to the north, this pattern forms the primary grid of the Government Complex. The Krishna River in the immediate site vicinity runs E - W. REGION: EXISTING AGRICULTURAL GRID JUXTAPOSED TO THE PROPOSED CITY GRID Central Park (similar in size to proposed Capital Complex) serves as an amenity for residents, a tourist attraction, and an important green environmental control system for the larger New York City area characteristics that Amaravati Capital Complex site can also encompass. CENTRAL PARK, NEW YORK, USA - 1857 2. Derived from the larger scale Krishna River flow, prevailing wind direction, and current agricultural grid (plots and irrigation systems), this pattern runs in a NW - SE direction. Current village formations follow this grid. In our opinion, the landscape of the Government Complex should respond to existing scales and patterns as well as the proposed, idealized ones. The Central Axis linking the site North to South is based on ideal cardinal directions and Vastu considerations. This axis could be inflected by the orientation and scale of the exigent grid, to create a less monumental /more accessible network of open spaces - a “people’s axis” in the context of a “central park for government.” CAPITAL CITY: RELATIONSHIP BETWEEN SITE AND EXISTING VILLAGES / WATERWAYS AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 03 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING MASTER PLANNING: URBAN GROWTH CONSIDERATIONS An examination of larger scale Amaravati planning studies from the consultant Surbana show some tendencies on projected growth and development of the urban area, following initial construction of the Government Complex. While current master plans have been updated to include the northern end of Justice City as an institutional zone, earlier versions show these locations are earmarked as housing and commercial zones, rather than institutional. LAND USE PLAN, DECEMBER 15, 2015 Other studies in the Stage 1 Presentation document (January 2016) indicate that “priority projects” do not include the northern sections of Justice City. This seems to be in conflict with the stated intention to build the High Court as part of the seed development, but is congruent with separate studies of development patterns which clearly indicate city growth to the east (Vijayawada), rather than towards the south / Justice City. FINAL STAGE 1 PRESENTATION, JAN. 2016 STAGE 1 STAGE 2 STAGE 4 STAGE 5 STAGE 3 Above: land-use plans from Surbana Master Plan, indicating zoning patterns and priority developments. Below: time lapse development pattern from Surbana Master Plan. The southern parts of the city (Justice City area) are earmarked for later development. This follows historical city patterns - areas closer to water bodies develop first. We also assume that - ideally speaking - all three Government buildings should be located close to each other, for ease of movement and simplifying security zoning. Locating the High Court at the southern end of the site (northern tip of “Justice City”) will result in a high degree of isolation, especially during the initial years of Amaravati’s life. It will not be able to participate fully in the initial urban vision concentrated along the Krishna River. Overall, it seems clear that the planning documents are inconclusive on the overall structure and timing of Justice City within the larger development. It is for this reason, we assume, that the Competition Brief specifically allows for flexibility in High Court location and its relationship to Justice City. AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 04 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING MASTER PLANNING: SITING STRATEGY LEGISLATURE SECRETARIAT HIGH COURT Bangalore Legislature, Secretariat, and High Court are located in close proximity - the ideal arrangement in terms of internal relationships, document movement, and security. As a starting point for more detailed considerations of the facility siting strategy, the following general considerations / questions were examined: -What is the ideal relationship between the various government branches? -What are the precedents in Indian for siting Government buildings / complexes? -How is the site allocation diagram provided in the Brief best interpreted? Clearly the three Government Branches are best located in close quarters, as these institutions are interwoven conceptually and literally. Broadly considered, these facilities all require enhanced security, and related supporting facilities of similar grade and character. They are allied in spirit - all pillars of a working democratic system - and would naturally benefit functionally from proximity. Building in an existing urban fabric, it is of course difficult or impossible to achieve this idealized pattern. Chandigarh (a new city) is an exception and there are others; the example we found that most closely mimics an ideal relationship in built form is at Bangalore, pictured to the left. The Legislature and Secretariat assume a particularly close relationship, presumably necessitated by frequent physical movement of people and documents back and forth. Indicative zoning diagram provided in the Brief. Legislature and Secretariat are located in the Northern sector of the site, while the High Court is located to the south. Diagram showing the notional organization of Indian Government. The three branches serve simultaneously to create, engage, and interpret the law of the land. The Brief diagram seems to indicates a close relationship between the Legislature and Secretariat at the northern quadrant of the site, but locates the High Court well to the south. This follows the Master Plan location - the High Court as part of “Justice City” to the South. The Brief diagram, however, is only notational - and (as we have noted) the location of the High Court is singled out as open for interpretation by the competition participants. AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 05 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING MASTER PLANNING: FORMALITY AND FLEXIBILITY KRISHNA RIVERFRONT KRISHNA RIVERFRONT GOVERNMENT SECTOR BLOCK 1 OVERALL GROUPING: “FORMAL ZONE” BLOCK 1 BLOCK 2 HOUSING / CULTURE SECTOR Initial site planning considerations focused on the general character that should prevail on the site from North to South. Blocks 1 and 2: Government Sector - As we have noted, this is likely to form the most concentrated development area during the initial life of the city. Government Institutions should, as far as possible, be consolidated here, between the Downtown Road and the Krishna River. Blocks 3 and 4: Housing / Culture Sector - The blocks south of the Downtown Road will necessarily be comprised of housing and amenities supporting Blocks 1 and 2. - This clear initial distinction between Sectors allows for each to develop an appropriate synergy and scale and an easily legible character. BLOCK 3 “FLEXIBLE ZONE” GROUPING WITHIN BLOCKS 1 AND 2: BLOCK 2 BLOCK 4 Block 1: Formal Zone - This area has a strong connection and views to the Krishna River; it is highly visible. Accordingly, we believe that this zone should have the most formal development, both from a programmatic and an architectural point of view. It should be fully controlled /choreographed as part of the Master Plan by the Master Architect. Block 2: Flexible Zone - This area will be immediately accessible from the Downtown Road and defines the center of Capital City. The number and variety of Institutions in this larger Zone will require consolidation of a wide variety of factors in final planning. Accordingly, we believe Block 2 must allow flexibility in development and plus / minus considerations taken before finalization. AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 06 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING MASTER PLANNING: GOVERNMENT BUILDINGS KRISHNA RIVER LEGISLATURE HIGH COURT AMARAVATI SQUARE Right above: Legislature, High Court sited across Amaravati Square. Heads of Departments (HOD) are located adjacent to the Secretariat. Three main buildings have views over the Krishna River; the Secretariat is the tallest and sits in the Southwest corner, at the center of Government City and easily accessed via the Downtown Road. Right: Master planning allows for flexibility in locating the Secretariat. Option 1 provides best connectivity between Secretariat and Legislature. Option 2 puts the Secretariat at the center of the Institutional Block, with the best connectivity to various HOD sections. We believe this to be the ideal siting for the following reasons: - A complete and coherent urban vision will be evident from the beginning of Amaravati’ s history. Amaravati Square, bridging between the Legislature and High Court is considered part of this initial seed project - completed in 2019 and controlled / designed by the Master Architect as well. -The two main buildings will have a strong presence along the Krishna River, while ensuring that the Square remains open (Legislature and Secretariat are tightly bound by movement back and forth of Chief Minister, but High Court is not). Amaravati Square is fully public and the “people’s axis” continues uninterrupted to the River. -In terms of Vastu relationships, the largest and tallest structure - the Secretariat, seat of the Honorable Chief Minister - is located at the Southwest corner of the Government Complex. This building will also have views of the Krishna from the upper floors, the location of the Chief Minister and Chief Secretary Suites. HEADS OF DEPARTMENT SECRETARIAT Above: Proposed shift of High Court to a more prominent location, and the Secretariat to the Southwest corner of Block 2. This will eliminate isolation of the High Court complex, create better integration of government functions, and allow for a single complex (Legislature, High Court, and Amaravati Square) to define the new Amaravati City in 2019. KRISHNA RIVERFRONT CHIEF MINISTER RESIDENCE RAJ BHAVAN SECRETARIAT (FLEXIBLE ZONE) AMARAVATI SQUARE (FORMAL ZONE) CAPITAL RIVERWALK Based on the considerations outlined on the previous pages, our Master Plan proposes to shift the High Court to the north, sited in tandem with the Legislature, and Amaravati Square in between. The Secretariat is located at the Southwest corner of Block 2, with HOD buildings running extending north as shown. L HC DOWNTOWN ROAD L HC L HC S S S PROPOSED OPTION 1 -The Secretariat, which has 2000 visitors / day, is easily accessed along the Downtown road via car, bus, and future subway stations. It sits symbolically at the center of Government City as a whole. -Initial site level energy plant and infrastructure trunk line requirements are consolidated; the project can be completed more quickly / with fewer resources than if the High Court is located 3 kilometers to the south. - From a construction / phasing point of view, the first two major projects can be considered as a single site, simplifying construction logistics and sharing resources such as concrete batching / pre-cast / crane infrastructure.

Taller volumes are sited at city street perimeters, whereas bungalow types are located towards the interior (along the central landscape axis and along the Canal to the south). The intent of this massing is to afford all blocks visual and physical access to the central green space. Wind direction was a key consideration in the development of the staggered building siting strategy and the introduction of east-west green passages. These cross-corridors provide pedestrian and cycle access to the site perimeter and connect to nearby schools, parks, etc., effectively stitching different zones of the city together. The two expanded green “meadows” are enclosed and defined by larger housing volumes. These meadows accommodate the MICE (Meetings, Incentives, Conferences, Exhibitions) facilities from the Brief, as well as other cultural, and athletic facilities to supplement daily life. The zone perimeter is defined by thick tree rows, serving as visual and acoustic buffers against the busy street. East to West cross-corridors are also lined with green and coordinated with security zones to create a safe, shaded network of open space. Vehicular access to all plots is via the inner loop road only; parking is provided at all blocks via a combination of surface and piloti spaces below the housing volumes themselves.

Siting is intended to allow for easy passage / permeability of wind, and light, while still providing a shaded, safe environment for family life.

AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 08 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING MASTER PLANNING: OVERALL SITE ZONING KRISHNA RIVER AMARAVATI SQUARE ZONE PEOPLE’S LAWN AND CAPITAL RIVERWALK FORMAL Amaravati Square Zone: This will contain the first project built in Capital City - the consolidated Legislature, High Court, and Amaravati Square project - which will establish a firm presence along the Krishna River immediately. The Raj Bhavan and Honorable Chief Minister Residence are also located here, together with the connecting landscape to the River, known as “People’s Lawn” and “Capital Riverwalk.” Secretariat Zone : HOD and Government of India Buildings are located between the Secretariat and the Legislature / High Court group. These buildings define the lively “people’s axis” that connects these facilities and leads to Amaravati Square. The spine is animated with retail space and cafes, connected by smaller gardens and platforms that link north to south.

High / medium security zones characterize the extremities of the site, while the central areas are maintained with more open, residential-level security details. The Government sector can be considered autonomous and afforded higher levels of security without impinging on the resident’s freedom.

The Housing zone and Government zones are linked by an internal loop road which accommodates a dedicated bus loop system and bicycle lanes, reducing the demands on the external roads and providing internal, secure transport within the Government City. The development of Capital City should - if possible - occur with development of transportation infrastructure that can support its projected population. It is expected that these demands will first be met via bus systems, but eventually require subways as the population projections are met.

BIKE INTERNAL ROADWAY BIKE PED. 2 LEVEL PARKING HIGH SECURITY ZONE ROAD TYPE II LOW SECURITY ZONE 2 LEVEL PARKING SURFACE PARKING LOW SECURITY ZONE RETAIL “PEOPLE’S AXIS” SITE SECTION SHOWING “INVISIBLE SECURITY” VERTICAL ZONING Security zoning corresponds closely to program blocks. All zones at the perimeter are further secured via their sectional height (+25) above the surrounding landscape. The “People’s Axis” pathways are below this level which allows them to remain open and continuous. Where the public zones are raised to +25 level, continuous water features serve as security zoning demarcation, and the landscape continues uninterrupted, over the Bund Road, and connects to the Krishna River. PARKING ALLOCATION SURFACE PARKING (EL. 23.5 to 25.0) DOUBLE-STORY PARKING (EL. 21.5 + EL. 25.0) PARKING BELOW BUILDING (EL. 21.5) Note: parking numbers have been accommodated in the Master Plan as per revised program received on January 19, 2016. Legislature, High Court, and Secretariat parking layouts are contained in the architectural plan set. Other parking areas are sized on area / car allocation basis. MASTER PLANNING: PARKING AND SECURITY Each of program block is afforded dedicated parking defined via security zoning /control points. Surface parking is utilized where density is not a concern, or where avoiding parking under buildings is the goal. Double story parking (taking advantage of the site section as shown) is used where denser parking is required and security allows. Portions of the HOD and Housing Blocks utilize piloti space below buildings to minimize impact on surrounding green space and maximize convenience. Parking is used as virtual “fill” to allow building plinth level at +25m without massive soilworks. Levels below +25m are considered to be part of a lower security zoning. This easily-maintained vertical security stratification helps promote “invisible” security on site. AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 11 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING MASTER PLANNING: CULTURE AND ART PROGRAMS The daily life of Government City will be supplemented as follows, creating a vibrant, lively atmosphere throughout the day and evening. -The “Culture Meadow” in the People’s Axis contains MICE (Meetings, Incentives, Conferences, Exhibitions) facilities per the Brief. These are supplemented with a public observation tower (overlooking the site, landscape, and Vijayawada) and a historical museum highlighting regional history. These facilities target tourists and visitors who otherwise might not visit Government City. A library for residents can be developed with the Museum, or as a separate facility. -The “Athletic Meadow” houses a gymnasium, tennis courts, cricket ground, and swimming facilities for residents and visitors alike. CULTURAL FACILITIES -A dedicated art program will utilize the art budget not only to purchase iconic works, but to develop a continuing curated program of art events. The People’s Axis will become an outdoor museum for art installations of all types. The ever changing exhibits will draw repeat visitors, and offer a welcome change of scenery for residents and workers. Iconic works can be located around major Government buildings (in their secured courtyards) and other highly visible locations. ATHLETIC FACILITIES RETAIL AND PUBLIC FACILITIES -Food / Beverage / Retail locations utilize the separate and secured ground floor parking level of Government and Housing blocks, spread throughout the complex. These are supplemented by kiosks that add to the variety and texture of the People’s Axis and support daily life at all levels. ART PROGRAM RETAIL / F&B “ART ZONE” PUBLIC FACILITIES TEMPORARY / PERMANENT INSTALLATIONS TEMPORARY RETAIL / F&B KIOSKS PERMANENT INSTALLATIONS (SECURED LOCATIONS) OBSERVATION TOWER Left: A vibrant lightscape for the People’s Axis will be developed to attract visitors in the evening hours and ensure that the neighborhood is safe and lively even after the Government workday is complete. Supplementing standard safety lighting, this will help create a more secure environment “invisibly” . AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 12 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING LIGHTING DIAGRAM MASTER PLANNING: INFRASTRUCTURE / RENEWABLE ENERGY At this competition stage, it is difficult to assess energy infrastructure requirements; feasibility of specific proposals in relation to the coordination required with other disciplines is also limited. Accordingly, the current design is limited to broad principles, which will require confirmation and adjustment in accordance with Government officials and planners following the competition. The projected population for the entire Government City (including the Capital Complex) is over 200,000, with a working (daytime) population of close to 60,000 at the Capital Complex. Roughly 1/4 of the total population will reside within the Capital Complex itself. By this estimate, both the daytime and evening populations of the Capital City are balanced at close to 60,000 people. Under these assumptions, our rough cut consumption numbers are: Water: 21,000 cubic meters / day Sewage: 21,000 cubic meters / day (not including rainwater) Electricity: 201,600 MWh / year Energy, water, IT, and other service infrastructure will be brought to the site via Downtown Road. From this juncture, we are proposing a main looped branch to distribute services north and south. Redundant secondary loops service the Government Zones and the Housing Zones separately; we recommend separate back-up connection capacity be maintained for each (distinct from the Downtown Road mains). Both the main and sub loops will connect to 2 main infrastructure nodes (for electricity, sewage, and water plants). These have been established as clear zones in the Master Plan, but final locations of the required equipment plants will need further refinement as information is consolidated. Sub nodes and block level infrastructure nodes can also be expected as requirements, and will need to be coordinated together to ensure functionality and easy access without sacrificing the continuity of the Master Plan. If 10% of this electrical energy requirement is produced via renewable sources, the requirement is roughly 20,000 MWh / year. If the energy demand can be reduced via best sustainable building practices by 20%, the figure drops to 16,000 MWh / year. While this is a strict target, utilization of the extensive rooftop areas together with a looped storage and distribution system can be proposed to meet this demand. A balance will need to be established between this rooftop energy production, rooftop rainwater harvesting, and green roof insulation systems.

The extensive roof areas of the Capital City Complex offer ample opportunities to utilize this reliable and increasingly efficient technology. Care needs to be taken to ensure proper storage and integration with the available grid systems and avoid wasted capacity. AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 13 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING II - LANDSCAPE APPROACH LANDSCAPE PLANNING DIAGRAMS “PEOPLE’S AXIS” OPEN SPACE AXIS AND GREENERY The proposed “Civic Axis” is redefined as a series of human-scaled open spaces which maintain north-south connections to surrounding landscape while breaking down the monumental scale of this spine. “PEOPLE’S AXIS” WATER CONNECTIONS “PEOPLE’S AXIS” URBAN FORESTS (PLATFORMS / EXTENSIONS) AND PLANTED TREES Proposed waterways also take on a human scale, responding to specific activities, proposed facilities, and the overall network of connections to a proposed canal in the south part of the site. East-West Roadways are characterized by green cross connectors, “Urban Forests”. North-South Roads are sheltered by three rows of trees, serving as both visual and auditory buffers. This greenery provides a sense of arrival, contrast to the surroundings, and visual orientation for visitors.

Future subway stops will also be located in this area. HOD BUILDINGS HOD complex includes double-height corner spaces for waiting / lounge areas. These spaces can also connect or extend departments on different floors, giving the complex a rich programming flexibility in both plan and section. SECRETARIAT DOWNTOWN ROAD MICE FACILITIES CULTURE MEADOW OBSERVATION TOWER AMPHITHEATER DETAILED SITE PLAN: “PEOPLE’S AXIS” Housing blocks are designed to enclose semi-public interior gardens, and to allow for prevailing winds to pass through the block. The blocks themselves are staggered, in order to allow for better integration of greenery and also in response to the prevailing winds. Blocks are lifted at strategic locations to allow for the landscape to maintain continuity and provide a sense of openness in the East-West direction. To the north of the Downtown Road, the landscape is defined by the Secretariat and the Heads of Department (HOD) complex. The staggering of the HOD blocks breaks down their mass, and allows for the introduction of green courtyards that pass through open piloti spaces to create an East-West continuity. Landscaped paths and covered walkways cut across and through the buildings, creating easy connections between different departments and buildings. South of the Downtown Road, the “Culture Meadow” offers a wide expanse of greenery and water for visitors, residents, and Government workers alike. Programmed with the MICE zone (Meetings, Incentives, Conferences, Exhibitions), a proposed Museum / Library complex, and an Observation Tower, this will be an active and open zone throughout the day and evening. The Culture Meadow serves as the transition zone to the Housing areas to the south, where the People’s Axis continues its sequence of gardens, terraces, and pathways through to the southern tip of Government City.

The People’s Lawn provides area for viewing events in Amaravati Square and covers a 500-car parking lot for the Raj Bhavan and Honorable Chief Minister use. It also affords elevated views over the Krishna River. The car park can serve visitors to Capital Riverwalk or Parade viewers when not in dedicated use for a private VIP event. CONNECTION TO CM PEOPLE’S LAWN AMARAVATI SQUARE Above: view from Amaravati Plaza to the north. The Plaza doubles as a parade ground, with the inclined People’s Lawn serving as viewing area for this and other Plaza events. The lawn conceals a car park underneath that serves both the Raj Bhavan and CM Residence. Right: Example of shallow pool with fountain. Left: 1:1000 detail plan of Amaravati Plaza and Capital Riverwalk zone. The parade ground utilizes the East-West Road, lined on both sides with green spectator area, and then spills into the square. The Square is characterized by a shallow water pattern and fountains, but can be quickly and easily drained for parade use or when humidity is high. Both Legislature and High Court are high security zones; however, as there is not much direct back and forth between them, the Square itself remains public and the connection through the People’s Axis to the River can remain open for most of the year.

Considering this tendency to eschew tradition in the search for glitz and glamour, the important question is no longer “what is possible?”, but rather “what is appropriate?” in 21st century Indian architecture. FATEHPUR SIKRI As a fundamental principle of our design, we have adopted the goal of formality rather than monumentality. Monumentality is defined by Merriam Webster as “extreme, resembling a monument or memorial” - in other words, overwhelming and looking backward, rather than forward. Formality, on the other hand, is defined by Merriam Webster as “consisting of the essence of a thing” - in our interpretation, a sense of quality and permanence balanced with a sense of openness and accessibility. It is extremely important that government buildings in the 21st century have this transparency - not in the literal sense of having a lot of glass, but in the sense that they are open and reveal their internal workings to the people. The overwhelming scale of Louis Kahn’s work in Bangladesh, while powerful and memorable, presents a blank face to the world inappropriate for today’s India. Other, older examples from India’s rich architectural history offer better lessons. Indian temples have a sense of formality, but are well-animated by human-scaled walkways, water features, and courts - as seen at Chidambaram Temple in Tamil Nadu. The array of interconnected courtyards and gardens at Fatehpur Sikri is another inspirational model for modern public buildings. Based on these thoughts, the common strategies that guided our architectural design are: - Interplay of verticality and horizontality, giving movement and scale to each structure. - Important programs are given prominence while supporting facilities are lower and more connected to the landscape. FATEHPUR SIKRI - Piloti /open space on ground floor levels create connections and movement across the site to develop a greater sense of intimacy and community across the complex. - Low-tech facade systems admit natural wind and light and cut direct sunlight, creating comfort without dependence on mechanical systems. - Simply, clear forms utilize standard construction technology (RC, pre-cast) to ensure timely and economic delivery. CHIDAMBARAM TEMPLE Amaravati is an unprecedented opportunity to define an appropriate Indian architecture that looks forward while still respecting its past. We believe this chance should be used to its fullest potential, achieving a comfortable, enduring, high-quality environment for the Andra Pradesh government and setting a new standard for India as a whole. AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 22 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING LEGISLATURE: GENERAL PRINCIPLES The design of the Legislature, beyond satisfying complex circulation requirements, is based on the clear expression of its three fundamental spatial types - the Assembly and Council spaces, the surrounding office spaces, and a proposed third connecting public space called the “Agora”. The Assembly and Council spaces are given a distinct, formal quality commensurate with their importance and responding to their highly specific program. Surrounding administration and courtyard spaces are designed as low-rise, easily legible spaces full of greenery and water features. Lower volumes are fitted with extensive exterior shading devices tuned to block direct sun while reflecting natural light to the interiors. The primary cladding material will be white Indian granite, with recessed accent walls in contrasting red travertine. LEGISLATURE SEEN FROM AMARAVATI SQUARE All entries to the Legislature are from the North, with separate access for VVIP, VIP, Administration, and Media / Visitors. Security boundaries are clearly defined and dedicated circulation paths are established for the different constituents.

When Legislature is in session, the Agora is a secure place of dialogue and discussion for members. When the Assembly is not in session, this Agora can be opened for more public use - hosting events, exhibits, lectures, etc. - and connecting Amaravati’s populace to the institution. The Legislature can be seen not as a distant monument, but as a part of city life during these events. AGORA Though seemingly an informal aggregate of interior and exterior spaces, the Greek Agora was actually a sophisticated multi-use complex, serving as a market, event spaces, and community center. Wikipedia describes the Agora as “ . . . a central spot in ancient Greek city-states. The literal meaning of the word is "gathering place" or "assembly". The agora was the center of athletic, artistic, spiritual and political life of the city . . .” PRIENE AGORA, 4th CENTURY BC MEDIA VISITORS SPEAKER CM MEMBERS SECTION A AMARAVATI GOVERNMENT COMPLEX CONCEPT DESIGN COMPETITION - 24 MAKI AND ASSOCIATES ARCHITECTURE AND PLANNING LEGISLATURE: ASSEMBLY AND COUNCIL CHAMBERS The Assembly and Council spaces are composed of dynamic double-ring spaces, formally expressing a sense of optimism and outreach - a complex but fully functional expression of the program inside. NATURAL VENTILATION The interstitial zone between rings houses support spaces and suites for the Honorable Chief Minister, the Cabinet Members, and the Speaker. The Chief Minister is afforded a generous double-height office adjacent to the Cabinet Minsters, while the House Speaker enjoys an expansive lower level office directly behind his chamber seat, with views of the surrounding greenery. DIFFUSED NATURAL LIGHT This double structure insulates against noise and heat, and also houses mechanical /service zones. The inner shape can be tuned and treated for acoustics freely without compromising the exterior, a flexibility that will allow for easy changes and expansions. SUPPORT / MECHANICAL HONORABLE CHIEF MINISTER VISITORS ASSEMBLY HALL The double ring roof structure is mobilized to admit natural light and exhaust hot air, reducing overall energy loading.

HONORABLE SPEAKER SECTIONAL PERSPECTIVE OF ASSEMBLY HALL FLAT SLAB WALL STONE CLADDING EXTERIOR COLUMNS FLAT SLAB FLAT SLAB PRE-CAST SUBSTRATE Structurally, the Assembly uses inclined columns clad in pre-cast panels to form the exterior shell shape. These columns are tied to horizontal flat slabs integrally cast with the inner ring walls. The inner ring walls are solid cast to provide acoustic insulation and lateral stability. Depending on the temporary shoring systems available, it may be possible to pursue the framing of both inner and outer rings simultaneously, saving time on site. Exterior panels can be pre-cast prior to completion of the structure, so that there is no time loss enclosing the building once the concrete frame is complete. Integral pre-casting of panel and finish can also be examined for further time savings.

The Court block overlooks Amaravati Square; Administration and Staff blocks are housed in a series of lower volumes and courtyards behind this main volume. The Court block will be clad in white granite, with a variety of punch openings and screens to allow for air flow while cutting direct sunlight. The Chief Justice’s Courtroom is given added volumetric presence at the center of the block; movements of Advocates throughout the atrium will be visible behind the stone sun shading screens. Administration volumes will use a pre-cast stone clad panel system for sun shading at exterior circulation zones, with offices further sheltered inside these zones. Circulation routes ensure that Judges, Advocates, Staff, and visitors remain within their designated zones and do not cross paths. HIGH COURT SEEN FROM AMARAVATI SQUARE Siting of the High Court ensures that all entries are from the North. Staff, Visitors, and Advocates share one vehicle entry, while the Judges have a dedicated entry. Parking is also kept in separate zones; advocates and visitors share a single zone on separate levels, staff another, and judges cars park in a highly secure underground area.

Movement and activity inside will be visible to the public through stone jali screens, revealing the workings of the Court to the public without sacrificing security. The atrium interior accommodates the Advocate independent circulation and gathering areas. Filled with diffused light from above, the Atrium is characterized by its crossing bridge elements and reflecting pools below, adding to the dynamism. Finishes include high quality light-colored Indian stone and hard wood, with accenting Indian stone for vertical circulation shafts. Honorable Judge Chambers occupy the exterior layer of the Court block, with access to direct and indirect natural light and ventilation through operable windows and screens. Judges circulate via a completely independent circulation system, including a dedicated car approach, below grade secured parking, and entry sequence. Courtroom spaces are sandwiched between the Atrium and the Judge chambers at the perimeter. Natural light and ventilation reach the Courtrooms through continuous “eco-void” (ecological void) openings connecting to all Courtrooms. Natural stack ventilation will ensure that hot air is pulled up through these eco-voids from the building base, drawing out hot air along the way. These natural systems are supplemented by air-conditioning to ensure comfort throughout the year.

Major shared departments consolidate in the front Tower, with other Department groups consolidated in a lower volume to its west enclosing a sheltered courtyard. The siting of the Tower - at the center of Government City and facing the “People’s Axis” - make it clearly the face of the State Government. The Minster’s Suites are located at the top of the Tower, with generous panoramas over the surroundings and the Krishna River. Horizontal stone louvers cut direct sunlight, allowing softer diffused light in but allowing views out. The lower volumes also utilize environmental control louvers to cut sunlight but allow for cooling winds to pass through. The louvers are clad, like the Legislature and High Court, in white Indian granite. SECRETARIAT SEEN FROM DOWNTOWN ROAD Siting of the Secretariat ensures that all entries are from the North. Staff and Visitors share one vehicle approach and drop-off, while VIP (CM, CS, and Cabinet Ministers) are afforded a separate dedicated entry. Parking is shared in a lot west of the building. A separate smaller lot serves the multi-purpose outdoor space for Secretariat employees. VIP ROUTE STAFF ROUTE VISITOR ROUTE The Secretariat’s lower blocks surround a central courtyard bringing natural light and air to the offices and itself filled with greenery and water.

NATURAL VENTILATION WATER COURT ENTRY ZONE TOWER GARDEN AXONOMETRIC TOWER SECTION THROUGH INNER COURTYARD The main Secretariat Tower and lower office zone volumes work with passive technologies to create a comfortable work environment without relying on mechanical systems. The passive systems reduce mechanical loading, enabling smaller mechanical plant rooms and creating a healthier work environment overall. All offices have access to both natural light and air. On the exterior, brise-soliel systems cut direct solar radiation while allowing air and light to pass through. These systems are tuned to orientation and visually help signify the different zones in the complex when seen from a distance. Sheltered zones facing the inner courtyards also benefit from diffused natural light. The atrium itself will create upward drafts of warmer air that help pull air through and across the office spaces. The Secretariat Tower is animated by a series of green / natural spaces that connect upwards throughout the building. The entry-level water court creates evaporative cooling effects for the surroundings. Middle levels include a green terrace at each level, facing a different direction but connected at the corners - creating a continuous “green spiral” at the building perimeter. Upper VIP zones include dedicated inset gardens on each side, allowing for generous views over the Krishna River, Amaravati City, and Vijayawada on clear days. Circulation routes for visitors / staff and VIPs are kept distinct, but all employees enjoy the benefits of the different courtyards and a comfortable office work environment.

This is accomplished through the strategic use of brise-soliel elements that shade direct sunlight, but still allow for indirect natural light and air to penetrate building interiors. VERTICAL LOUVER 4 different systems are mobilized to accomplish this, depending on orientation and program needs: 1. 2. 3. 4. VERTICAL PANEL Each of these systems has been utilized in past projects, and this experience will be mobilized to fine-tune their design and ensure buildability and quality in the Amaravati installations. The location diagrams to the left identify where each type is used on each of the three main buildings in the Capital Complex. HORIZONTAL SHADE WITH LIGHT SHELF Mechanical plant room sizes will be minimized via extensive use of VRV systems for building cooling (where mechanical cooling is demanded); again, best practices will drive the design towards use of passive techniques that obviate the need for mechanical cooling wherever possible.
