Introduction
RPBW was asked to prepare a design for the new
restaurant on the roof of Nemo.
A new inclined glass roof will substitutute the existing roof entrance, allowing daylight to come into the
restaurant and make it into a primary place to visit
and to enjoy.
In our concept design for the entire roof (July 2012),
we proposed a tensile structure, but a glass structure
will be an even better match.
The circulation and lay-out of level 5 will need to be
defined and approved before we can proceed with a
final design.

Nemo will work with a retail specialist for the branding and interior design of the restaurant.
RPBW would like to be involved in the this process,
to make recommendations to the client in order to
guarantee the integrity of the architecture of the Museum.

In 2013 Nemo established a green roof on the roof of
the existing restaurant according to our concept design, with new planter boxes and a variety of plants
that flower in different seasons.
The garden on the upper roof will set the stage for
rest of the Nemo roof, an integrated design of elements of green, light and education to make the roof
into to one successful experience.
The green roof will increase the thermal buffer capacity of this roof, and temperatures are to be expected to be significantly lower in the summer.

On the lower part of the roof new exhibitions are being studied, inspired by the four elements.
This design will hopefully become an integrated part
of the whole Nemo roof, which will attract many new
visitors in the future.
page 5
One of the strong architectural elements of the sloping Nemo roof are definitely the horizontal lines,
made by the terraced concrete steps, the waterbasins and the new planter boxes on the upper roof.
The new design for the restaurant will work well with
this framework, as orientable louvres on the new volume will be read as part of the same language.
page 6
The roof of the new extension will need a certain
height and having the same inclination as the roof of
Nemo, the extend in plan is liminìted by the proportion of the the roof in elevation.
The elevations have been studied with great care, to
maintain the balance of proportion in the facade.
The proposed roofline of the Restaurant incorporates
the volume of the lift tower and balances the roofscape even more.

Design
RPBW’s design is based on the concept of creating a contiguous and luminous space on floor 5, and
transform the existing entrance into the best place to
sit, eat and enjoy the view to the city of Amsterdam.
Especially in the warmer seasons, the terrace in front
of the new glass house or “Serre” will provide a lot of
additional seating and opportunities to use the roof
of Nemo as a real Piazza, as originally intended.
The new design will have a flexible lay-out, allowing
for the use of various patrons, from school groups
and parents with their children, to commercial gatherings and parties after opening hours or in less
crowded times.
The glass roof will be spectacular from inside as well
from outside and the appeal of the new space will
rejuvenate the image of the public roof piazza. The
Exhibits on the roof, which are in development, will
connect seamless to the terrace of the restaurant
and the green upper roof.
The louvers on the roof will blend perfectly in the
“stepping geometry” of the roof, reinforcing the integrity of the roof as a whole.

Design Steps
1. The disembarking of the lifts towards the roof
and the view, is architecturally interesting, but occupies the best space of level 5 for the circulation of
the visitors.
The existing sanitary volume behind the lifts, uses
prominent floor space and takes away most of the
light coming from the south.
By moving the toilets, the elevators can arrive directly in the restaurant space and allows a much better
use also of the avalable space.
16.950+
2. The arrival of the stair from level 4 in the current situation, makes the circulation space consuming and the access control to the museum complicated.
Combining the new stair from level 4 with the lifts
in one area, will allow to control the access to the
museum efficiently with a minimum amount of space
and personnel.
3. The newly created space for the restaurant
towards the roof will be entirely glazed to open the
view, while the (inclined) glass roof will flood the
space with light. Louvres on the glass will protect
from exessive sun radiation and reduce the thermal
heat loss of the space during the night.
page 10
4. The new location for the toilets is above a
technical space on the floor below, makes the central
space more flexible and more luminous.
The visitor will be able to orient easily in the open
space and can enjoy the view towards the city from
every table.
5. A special dining\meeting room is created in the
west side of the restauarant.
A glazed movable wall allows to separate this space
from the main space, usable for private functions,
also during museum hours.
page 11
6. No windows will be blocked on the west facade
as the toilettes are positioned partly in the void to
level 4.
The existing “McKinsey” stair will thus need to be
eliminated, also because a stair in this position would
mean a complicated access control problem.
page 12
7
Green around the terrace will greatly improve
the ambiance, but needs to be integrated in the step
design of the roof, instead of made with individual
vases of different shapes and colors.
Maybe some of the proposed modular planters proposed in the concept design for the roof could be
used to add to the terrace.
Slender vertcal elements work quite well in the composition of the design.
The existing flagpoles are very elegant and also the
large fabric umbrellas are definitely to be kept in
some fashion in the final design.
8. As the glass Serre will be larger than the existing entrance, the terrace needs to be enlarged, or at
least be used more efficiently.
page 13

page 14
9. The cantilevering glass of the Serre will provide an area protected from the rain.
The water feature will need to be slightly reduced
(leaving the flat area for seating) but a new water
exhibit can be placed at the top basin for children to
play.
The two stepped areas to the east and west of the
terrace, are cannot be used for seating and because
of safety provisions, are actually impeding views
from the restaurant.
Eliminating the sloped parts and extending the terrace in these locations will provide 65m2 extra terrace and open the view from Dining II to the City.

page 16
Organization of level 5
A new control area will be established in the place
of the former toilets. The lifts will open towards the
north and the open stair from level 4 will be moved
and arrive in the same place.
The kitchen remains where it is, but there may be
possibilities to make the kitchen more efficient and
use the extra space to the north side.
The self-service food distribution will be laid out
adjacent to the kitchen and will allow a view into the
preparation area.
Dining I
A flexible table arrangement along the glass wall
facing the void to the exhibition space on level 4,
will satisfy as well museum visitors with families and
school groups.
From here the roof and the view to the city can now
be appreciated.
Dining II
Towards the Westside of level 5, a dining\function
area has been created, with views to the roof and
towards the center of Amsterdam.
This room can be separated from the rest of the
restaurant and will have its own conditioning. Further
possibly overhead projection with screen and for
example a bar.
Dining III
The new glass house, the Serre, will be a spectacular seating area.
The space is separated form the rest with a glass
wall, but always visually connected. If desired, a flexible dibìviding can be studied here.
In the warmer seasons the space overflows into the
generous terrace facing south.

Access Control
Lifts and stair from below meet in a Control Zone,
from where the access to the rest of the museum
can easily be checked with turn styles. The entrance
tickets will need to have a magnetic strip and the
presence of a museum person during busy hours
may be necessary.
Visitors coming up the roof can freely enter the restaurant and stay on the terrace. If interested in visiting the museum, tickets and should be for sale in the
restaurant.

intermediate stops) and thus allow visitors to come
to have lunch without having to go through the museum. The large elevator remains at the service of
the paying visitors.

Access after hours
Already part of the original design for the building,
the restaurant was supposed to be able to work
when the museum was closed, using the lifts currently in the project, accessible from a lobby on the
groundfloor.
In the evening the museum one or both existing lifts
can be programmed to connect the groundfloor directly with the restaurant..

At lunch time: the smaller existing elevator could be
dedicated to access from outside to the restaurant
(no intermediate stops) and thus allow visitors to
come to have lunch without having to go through the
museum. The large elevator remains at the service
of the paying visitors.
page 21
Glass House
The Serre will be similar to a green house, a place
full of light.
Our office is a glass house and RPBW has made
quite a few buildings that feature spaces that make
people feel to be outside, but at the same time protected.
Sometimes the exterior is nature or the sea, but in
Amsterdam it will be the sky and the city, which can
be experienced visually, but also physically trhough
the glass or just stepping out on the terrace.
Low Iron glass and a structure made of dsteel will
make the experience of lightness even stronger.
Light and Views
The proposed organization will allow a lot of daylight into the restaurant, which will make the space a
much better place to be. The views from the all the
dining areas will be greatly improved.
The central staircase and liftcore will be a clear reference for orientation, around which the activities will
develop.
page 22
Program of Requirements
Some requirements in the POR seem to be conservative, in relation with the minimum by code, but
also compared to the parameters used in the original
design of the building. In particular the ventilation
factors and allowable temperatures.
A critical look at the climatic and space requirements
may be of interest to see if these are realistic from a
design point of view, but also economically.
Building physics
The “Serre”, the glass extension, measures about
215m2 in plan, and its volume is roughly 900m3. The
façade area is 149m2, with a roof area of 240m2.
The glass roof (double glass) will be covered with
(orientable) louvers and the façade will be equipped
with exterior rollershades.
The glass will be low-iron glass with a good low-E
coating, to avoid the discoloration of the light coming
into the dining space.
Steel beams protruding through the façade will need
to be thermally interrupted to avoid condensation on
the beams in the winter.
Acoustics
The acoustical performance of the existing restaurant space will depend on absorbing material in the
space and under the roof.
However, for the Serre this will be more of a challenge, as opaque absorbing surfaces are almost
impossible. We propose to revisit the requirements,
as the space is obviously not a normal space: a
louder ambiance noise is to be expected and can be
accepted.
The choice of furniture should be guided by a positive contribution to the acoustic performance. We
are proposing acoustic roller blinds in front of glazing
higher in the space.
page 23
Air conditioning
The restaurant north of gridline 4 will be conditioned
with air, as before as the envelope does not change.
The routing of the ducts will be changed. For Dining
room II a separate system will be required as the use
is different.
The Serre, will be air-conditioned, but in addition to
this we propose for the colder season floor heating
and open (fin) radiators along the glass façade, to
reduce the cold air drop.
In the Summer we use the tubes in the floor for cooling, in combination with natural ventilation of the
space, to top off the temperature on the warmest
days.
Electrical
Electrically I believe that the current situation has to
be reorganized, as the restaurant space was adjusted for offices while the Serre will need a completely
new design.
We want to investigate the use of LED fixtures and
power saving movement detection in the space.
Photovoltaic cells were already considered in our
concept design for the roof, used as steps on the
roof, substituting the concrete elements. Maybe this
could become reality for a small area, adjacent to the
Serre, used as an exhibition?

Structural comments
The existing entrance and roof (south of grid 4) will
be demolished and substituted with a glass house
with an inclined glass roof and aluminium louvres on
top.
The structure will be a steel structure and primary
and secondary beams will need to be welded together in the same plane to make the roof as compact as
possible and gain more usable space, as the height
of the roof is fixed.
The roof will cantilever generously and the steel
structure needs to be structurally continuous between inside and outside.
A void will be created in front of the lift for the new
stair and the existing void will be closed.
The lift doors are to be moved to the north side of the
shaft, so openings in the concrete lift wall will need
to made for this purpose.
Fire Safety
The lay-out as described has been discussed briefly
with the Fire consultant.
The new organization is feasible without the need of
significant adjustments.
We assume that the steel structure of the Serre can
be protected with slightly heavier profiles or if needed with intumescent paint.
page 26
Wind protection
After study have introduced a revolving door in the
restaurant façade to eliminate the draft issues experienced by Nemo in this very exposed location.
other geometries are possible, but use more space
or do not work as efficient.
As this element will be quite visible in the façade, the
detailing should be as light as possible.
A full, single glass typology is needed to reduce the
impact to a minimum.
When the wind is not strong and the temperature
allows, also the normal swing doors can be used to
enter and exit the Restaurant.
page 27
Maintenance and Cleaning Glass roof
The louvers on the glass roof are organized in panels, which can be operated separately.
Each panel is hinged on one side and can be lifted
(like a door) to access and clean the glass below.
A simple piston will be used to lift the panel and catwalks (with safety cable provision) will allow access
over the roof.
