HANSE HAUS can today look back on over 80 years of experience in the construction industry and more than 30,000 completed houses. With 360 permanent employees – some from their families‘ third generation of HANSE HAUS workers – and around 30 apprentices, the company has unrivalled knowhow in prefabricated house construction. The Schörghuber Group Putting faith in a reliable construction partner When choosing a construction partner, it pays to play it safe. HANSE HAUS is a subsidiary of the Schörghuber Group, which operates successfully in the hotel industry as well as the fields of aircraft leasing, beverages, property and construction, both in Germany and internationally. Many of the family-run group’s building projects, including the Arabella Park in Munich and the current redevelopment of Berlin’s Zoobogen, have had a major influence on the urban development of several German cities. Sustainability and energy efficiency – even on a large scale One of the largest projects for the Schörghuber Group’s property and construction arm is the m.pire in Munich. This imposing landmark on the north of the city is unmissable and unforgettable thanks to its unique combination of light, glitter and transparency. At the same time, it constitutes a modern emblem of sustainability and energy efficiency that the German Society for Sustainable Construction certified in advance with its Gold Seal of Approval. 5 6 Bespoke design, whatever the size, whatever your needs We build houses OUR CUSTOMERS want and so we never build the same house twice. At HANSE HAUS we realise that all of our customers are different people with different ideas of how they want to live. There are commonly a multitude of questions that will arise as soon as one begins to imagine building their own home; What kind of house do I really want to live in? How should the house be designed to suit my family now and in the future? Will my dream home be received well by the local planning department? Will my budget match my ideas? We always aim to deliver the house YOU really want and are able to help you at every stage of the process. We will happily take your ideas and transform them into the highest technical design. The following designs are meant as EXAMPLES only. They are able to outline some variations in styles, living space and design features. 2 storey 4 bedroom house Approximate floor area – 116m2 2 storey 3 bedroom house Approximate floor area – 152m2 2½ storey 5 bedroom house Approximate floor area – 362m2 7 HANSE HAUS: Where every home is high efficiency UK Building Regulations are there to protect us and ensure that any new home is built to a required standard. The Government has set a route map for the continued improvement of sustainable design and construction of new homes. There is a requirement that by 2020 all new build homes must be near to Zero Carbon standard. A house from HANSE HAUS is typically three times as energy efficient as the current UK minimum requirement. To achieve this, HANSE HAUS pays particular attention to the building envelope of your home, delivering external walls, floor build-ups, roofs and windows with superior thermal u-values than would be used in typical UK construction practices. HANSE HAUS are also experts in the construction of exceptionally airtight homes. This is a specialist process developed over the 80 years HANSE HAUS has been creating low energy homes. For more information, please contact your local agent and allow them to advise you on the latest requirements, as definitions are changed regularly.

So let your imagination be our guide and let us to make your dream home a reality. *As determined by German energy performance assessment standards HANSE HAUS 15kw Passivhaus HANSE HAUS Passivhaus The Future of Energy Saving In a Passivhaus, there are a multitude of technical construction details which have to be taken into consideration and have to inter-connect. Particular attention is paid to the airtight construction of the building envelope - the shell - to ensure that no heat can leak out through joints or gaps. Thermal bridges and any areas around the building where heat can be lost, are reduced to a minimum. In a HANSE HAUS Passiv Haus, the entire construction process and the individual structural elements, such as the walls, windows and roof are verified by the Passivhaus-Institut in Darmstadt, Germany. This Passiv Haus certification provides official confirmation that the building is built to the correct specification. For more detailed information on Passivhaus, please ask your agent for our brochure or visit www.passivhouseinternational.org HANSE HAUS are proud to be a Certified Passivhaus builder 9 HANSE HAUS Visitors and Sample Centre, Oberleichtersbach, Germany 10 Pre-build specification enables fixed contract sum Customised service packages Market Leading brands By choosing the requested services, our customers can select between two different service packages ‘STARTER’ and ‘TURNKEY’.

In the past buildings were ‘leaky’, and much of the required ventilation was provided by the high level of air leakage and uncontrollable window trickle vents. Modern building regulations however require buildings to be far more airtight. This legislative requirement for new buildings has arisen as a result to conserve fuel and power. The building regulation requirement throughout the UK is that the air infiltration rate should not exceed 10 m3 per hour per m2 at a pressure of 50 Pa. With Hanse Haus, air tightness is a priority from the start of the production line to the completion of the build. Our recently finished Passivhaus in West Somerset achieved an air infiltration rate of 0.45m3 per hour per m2 at a pressure of 50Pa – well in excess of Government requirements.

Heating & Environmental Technology 14 Air Source Heat Pump Ground Source Heat Pump How it works Even cold air is full of energy and air source heat pumps use the freely available heat in the ambient air to provide efficient heating and hot water at air temperatures as low as -25 °C. Because the source of heat – the air – is abundantly available all around us, air source heat pumps have the advantage of low installation costs and minimal space requirements, making them ideal for new build applications. Suitable for either indoor or outdoor installation, air source heat pumps can be used for heating, cooling and to produce domestic hot water and with the relatively mild winter temperatures in the UK, can achieve seasonal co-efficient of performance comparable with ground source, meaning excellent levels of performance can be achieved throughout the year. How it works The earth stores an enormous amount of solar energy from both solar radiation and rainfall, ground source heat pumps extract this freely available energy to provide low cost, low carbon, high efficiency heating and hot water. To extract the energy ground source heat pumps use collectors, filled with a mix of water and antifreeze, buried in the earth, either horizontally or, if available land area is limited, vertically. Although more costly to install than an air source heat pump, with the constant temperatures below the surface of the earth throughout the year, ground source heat pumps deliver high levels of efficiency all year round irrespective of seasonal variations in air temperature. Gas/Oil Condensing Heating System How it works Modern condensing boilers simultaneously generate warmth for heating and for hot-water provision through the combustion of gas or oil. By using the heat that remains in exhaust gas, the energy content of the fuel is used almost in its entirety, making gas-fired condensing technology especially efficient as well as very convenient. These boilers can be wall or floor mounted and an appropriately sized model will be installed depending on the heating requirement of the individual property. Heat Recovery Unit How it works With air tighter new buildings, whole house heat recovery ventilation is the most effective ventilation strategy on the market. Heat recovery continuously extracts humid air from wet areas such as kitchens and bathrooms and using a heat exchanger, transfers the heat to filtered incoming outside air which is redistributed to the living areas and bedrooms. Heat exchangers are up to 93% efficient which significantly help reduce heating bills, plus the effects of condensation are dramatically reduced. Home Technology Rainwater Harvesting Solar Water Heating PV (Photovoltaics) Integrated Technology Rainwater Harvesting works by taking the rain from your roof gutters, filtering out leaves and debris and storing the water in an above ground or underground tank. This water can then be used for non-potable applications such as vehicle washing, irrigation, toilet flushing and washing machines. Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to warm water which is stored in a hot water cylinder. There are two types of solar water heating panels, they are evacuated tubes (like in the picture above) and flat plate collectors. Flat plates collectors can be fixed on the roof tiles or integrated into the roof. An air source heat pump heater can be used as a back up to heat the water further to reach the temperature set by the cylinders thermostat when the solar water heating system does not reach that temperature. Solar PV panels require only daylight, not necessarily sunlight to operate, and they are therefore capable of generating electricity even on cloudy days. Solar PVs will work equally well in urban or rural locations and can be installed on the roof of most homes that can support the equipment. They can easily be connected to a building’s electricity supply and any unrequired energy can be sold back to the national grid. When in use, Solar PVs do not generate greenhouse gases or cause pollution. Each kilowatt-peak (kWp) of electricity produced can save approximately 455 kilograms of carbon dioxide emissions compared with electricity generated from fossil fuels.

We found out, through experience, that HANSE HAUS follow through with what they promise. The actual build was faultless and they worked incredibly efficiently to build us a quality house. The after sales service has also been fantastic.’ Has your new home met your expectations? ‘It’s definitely met our expectations. We love the house and the overall finish is excellent. We took a few months to learn how to ‘drive’ the heating system and now that it’s summer time, it does get hot inside when the sun is shining in. We need to learn a bit further about how to keep it cool. In the winter months, even through the very coldest spell, it was beautifully warm inside. It’s early days still, but we can already see that it costs about a third of our previous house to run which is fantastic. COMPLETE START TO FINISH BUILD TIME – 10 weeks Case study – Nottingham HANSE HAUS customers in Nottingham did some designs for a conventional build but after putting it out to tender they found the costs were way too high and that it was outside of the remit for most traditional builders to build an energy efficient house. It became clear to them that to achieve energy efficiency, the two most important factors were to build a house that was airtight and well insulated so they set about the search for companies that offered this. ‘HANSE HAUS stood out in terms of investment they’ve made in machinery at their plant. We also visited a couple of houses that they’d already built in the UK. We found that HANSE HAUS had the edge in every aspect of technology and we felt their highly efficient manufacturing process would achieve the house that we wanted.’ The Build At 6.30am on the first morning, two lorries arrived from Germany, with our house on board. The construction crew worked incredibly hard and were very nice people. Even having started so early in the morning, they were still working at 8.30pm that night and we actually had to ask them to stop out of consideration for the neighbours! From then on, they worked from 7 ‘til 7 each day. We were on-site virtually all the time just to watch and take photos. The whole build was seamless and in less than 8 weeks the house was completed. 20 Case study – Tewkesbury Has your new home met your expectations? Yes, it has. The house is really lovely and warm (and not drafty) even through the cold winter months. We did light our wood burning stove just once when we first moved in but it quickly became too hot and we found ourselves opening the windows. It’s really unlikely that we’ll need to use the underfloor heating on the ground and first floors at all. The basement is naturally a bit cooler, so it might be needed from time to time down there. We do sometimes turn the ventilation system off as we like to open the windows for fresh air. However, when it’s on, which it is most of the time, the whole house has a really lovely quality of fresh, clean air. Given your experience, can you offer any tips to other self builders? One of the things I would advise someone else to consider is that you need to allow space for all the machinery that is required to run the house. I would advise anyone to build a designated plant room into your design, either into a basement or a small utility room for example. COMPLETE START TO FINISH BUILD TIME – 10 weeks For HANSE HAUS customers in Tewkesbury, the motivation to build their own house came primarily from living in older houses, including a listed building for more than 30 years. ‘They were lovely to look at but had little effective draught proofing and were difficult to insulate properly. Coming originally from countries with cold climates, we knew what it was like to live in a well-insulated draught-free house, feeling warm, even when it was –20C outside. We’d already met the main HANSE HAUS sales agent in the UK and instantly took to his hands-on, can-do attitude. Once our house was delivered, the HANSE HAUS construction crew were fantastic. They took great pride in everything they did. They would start at 8 in the morning and finish at 6pm, or 1pm on Saturdays. They were so keen to get on with the job, they had asked if they could work until 10pm as the evenings were becoming lighter! So, what are your overall thoughts on building with HANSE HAUS? They have given an exemplary service. We feel that, as customers, our best interests have been at heart to the highest level and we’d happily go with HANSE HAUS if we were to self build again. 21 Case study – Braintree, Essex 22 HANSE HAUS customers in Braintree, Essex found a plot of land which was being sold off by the neighbouring house and then began researching how best to go about their build. ‘After researching many different companies, we decided on HANSE HAUS, who offered us the security of building on time and on budget. Given our previous experience, we knew that the efficiency with which HANSE HAUS operate was to be of huge advantage and after visiting the German factory, we knew that the quality of build would be uncompromised. Although 3 of our children have left home, they still spend a fair bit of time here, along with their partners and friends so we wanted to build a large family home where everyone could have their own space. Knowing exactly what we wanted, we designed the house ourselves and submitted plans to the local council. As is usual with planning, there had to be some compromise, and in our case, it was with the exterior appearance of the house needing to fit in with the surrounding buildings. I had to submit my drawings several times before we got it exactly right, and ultimately I would have liked to build a more contemporary house but certainly internally, the house has a very modern feel to it and has, in many ways, exceeded all expectations.’ What are your overall thoughts on building with HANSE HAUS? ‘HANSE HAUS have been incredibly efficient from start to finish. Firstly, and given our previous experience, the benefit of knowing exactly what the build was going to cost before we even started, was invaluable. Secondly, HANSE HAUS opened our eyes to a different, and more effective way of building – they work at the edge of design and use all the latest technologies. They also have an extraordinary level of commitment to the job and find a way to overcome any issues which might arise as well as accommodating changes wherever possible. Thirdly, we felt like we were being looked after, as a valued customer, throughout the entire process. Even when the house was snagged, HANSE HAUS picked up on things that we couldn’t even see, and went that extra mile to meet their own high expectations.’ Has your new home met your expectations? ‘It certainly has, it’s a fantastic house to live in and everything about it, is good quality. Despite the size of the house, we’ve also noticed a vast reduction in energy costs. With all 4 teenagers, and sometimes their partners and friends in the house, we were concerned about the running costs but we needn’t have been. In addition, with the rainwater harvesting system, we’re also paying less for our water. This is obviously a bonus for us, but is also good news in terms of the possible re-sale value of the house in the long term.’ COMPLETE START TO FINISH BUILD TIME – 8 weeks ‘HANSE HAUS picked up on things that we couldn’t even see, and went that extra mile to meet their own high expectation’ ‘We signed the initial contract with HANSE HAUS in July and after another trip to Germany to choose everything from the bathroom suites to the ceramic floor tiles, we came home to start work, with the ground workers, on the foundations and the concrete pad. We did come up against some unexpected problems during the dig out, but the experienced ground workers who were recommended by HANSE HAUS, did a fantastic job of redirecting errant pipework while meeting the differing standards of both UK and German regulations.’ 23 Case study – Certified Passiv Haus, West Quantoxhead Somerset The property owners found out about HANSE HAUS in March 2009 at The National Homebuilding & Renovating Show. After consideration they settled on building a HANSE HAUS Passivhaus, which was to be the first certified built in the UK. The property owners commented that- ‘HANSE HAUS stood out for a number of reasons. We particularly liked the idea that, unlike many other companies, we would be dealing 24 directly with the manufacturer. Having visited the factory and sample centre in Germany in June 2009, the quality of the HANSE HAUS product was evident. It wasn’t just this though; we were also placing our trust, and investing in, the people we were dealing with. Their cando attitude shone through.’ ‘Although energy efficiency and associated low running costs hadn’t been a primary objective when first setting out to build our own house, it became more apparent that these factors did make long-term economic sense. In the end, the fact that we’ve built the house we wanted, which is also a Passivhaus is the icing on the cake.’ What are your overall thoughts on building with HANSE HAUS? ‘The quality and speed of build is excellent. Also, when the house was being constructed, we watched the crew work with great precision and efficiency, even clearing and tidying as they went. The quality of workmanship was paramount. All in all, it’s been a really good experience and we would do it all over again’. on my doormat any more, puts a smile on my face. We had oil-fuelled heating and hot water in our old house which cost a small fortune. Those costs would likely have doubled after the cold winter we’ve just had, and the increase in fuel costs. Our new house feels so much warmer in comparison and that’s without having any heat on at all!’ Given your experience, can you offer any tips to other self builders? Has your new home met your expectations? ‘The house has definitely met our expectations. From paper to the finished version, we have the house that we wanted. We love the big windows which make it a really light, airy house and it’s position means that the sun pours in to every room at some point throughout the day. In the design process, there were some things that we weren’t in control of such as the staircase, although we’re really pleased with it. Like everything, it’s manufactured to a very high quality. The same goes for the windows and external doors, which are really solid and robust as well as being triple-glazed. The house is quite exposed and we used to hear the wind whistling through our old house but it’s so quiet now. Although energy efficiency wasn’t our main concern when we first set out to build our own house, the fact that I don’t have a gas bill landing ‘It’s essential to be fully involved in the design process of a house and pay attention to the details. When we went to Germany for sampling of fixtures and fittings, we’d made a decision on where we wanted everything to be placed but over time, you get to reflect on things like the position of the lighting, for example. Some things have worked out wonderfully well for us but for other things, like the lighting, we had to make a few minor tweaks, as well as a few compromises. I’d also say that, especially if you’re self building whilst also working full time, the Turnkey Service is what you need. We run our own business so although we were very involved with the design and the fixtures and fittings for the house, our involvement with the actual build was minimal’. COMPLETE START TO FINISH BUILD TIME – 8 weeks 25 After struggling to find a home to match their needs, HANSE HAUS customers from Elstree began to look into the possibilities of self building. ‘We started looking for a 4-bed property with a garage, and a kitchen big enough to eat in. We also wanted to be within walking distance of the station and thought we’d find somewhere that needed a coat of paint but not much else. That wasn’t the case! There was just nothing like that available on the market so we started to think about the alternatives.’ The couple started researching for a suitable build partner and found HANSE HAUS along with other manufacturers on the internet. ‘We then went to the Homebuilding & Renovating Show at the NEC and also Ecobuild at Excel where we talked to the various building companies. We showed the sales representatives our own concept design and this is when HANSE HAUS first stood out. Where others took one look at the vaulted ceilings and multi-levelled roof structure and said they couldn’t do it, HANSE HAUS had a can-do approach and invited us to Germany to discuss it further with one of their architects. Their attitude was refreshing and inspiring from the outset and no other manufacturer offered what they did both in terms of the package and costs. The HANSE architect in Germany was able to ‘tidy up’ our design and also suggest improvements here and there.’ Once the plot had been purchased, planning granted and the existing dilapidated 1950s home on it demolished, HANSE approved ground workers started to lay new foundations & drains. ‘A pre-manufactured house can be finished up to 9 months quicker than a traditional build and we had no concerns over budget as HANSE HAUS offered a fixed cost contract, which didn’t even vary with the fluctuating exchange rate. We were able to build a modern, functional, highly energy efficient yet very comfortable home, which is suitable for family life in the 21st Century. Now that we’re living in it, our new home really has exceeded our expectations.’ Case study – Elstree, Hertfordshire 26 Has your new home met your expectations? ‘Yes, the house has certainly met our expectations. We feel a real sense of calm and tranquility here. It’s really quiet and even though there are train lines nearby, we can’t hear them at all. This house is quite a selfish house in that, we designed it especially for us. It works for our lifestyle and felt like our home as soon as it went up.‘ Given your experience, can you offer any tips to other self builders? ‘It’s really important that you know what you’re signing up for from the outset. If you’re hoping that when you move into your new home, you’ll walk in and get your TV to work at the press of a button, be aware that, even with a turnkey service, this isn’t always the case. We had many issues with all the utilities companies (not just BT), which meant days of hanging around waiting for them to arrive with the right team of workers and the right equipment to make the necessary connections. This of course all amounts to extra time and cost. We would also recommend a ‘condition survey’ on neighbours’ houses, especially when you’re building a basement as this can prevent any argument further down the line about potential damage to foundations/ building.’ Coupled with the insulated shell, and the solar panels, the house is very economical to run. There is absolutely no wastage here. In fact, we’re our own little power station. Our project manager was excellent. Despite the problems with the plumbing and electrical work, he did everything he possibly could to assist the process and never once said it wasn’t his responsibility. HANSE HAUS have been a very dedicated company and are determined to leave us with a high standard product. At times this has even meant flying an engineer over from Germany at the drop of a hat, to fit a simple part. All in all, it’s been a really good experience. We would recommend HANSE HAUS and would build with them again ourselves. We placed our confidence in them from the start, and would do that again.’ COMPLETE START TO FINISH BUILD TIME – 20 weeks (including basement) So, what are your overall thoughts on building with HANSE HAUS? ‘From the start, HANSE HAUS stood out in saying that they can build almost anything in terms of design and they followed through on this. They have a can-do attitude, which is very appealing. They also offer a great range of fixtures and fittings – even the standard spec is top quality. We found that the staff at their sample centre gave excellent guidance and were very clear and honest about what was needed and what wasn’t – they didn’t try to sell us anything we didn’t need or want. HANSE HAUS really know what they’re doing when it comes to building energy efficient homes. Although our house doesn’t meet passive standards, (mainly because we wanted so many doors and extra windows) it does have passivhaus features, including the entrance lobby which acts as an airlock, and the heat pump. 27 Before getting started – what other costs should be considered? Building your own house is for most, a once in a lifetime event. Hardly surprising then that the majority of people have little or no directly relevant experience on which to draw to help them make the right decisions or take the right steps at the right time. The first time around most people will see the granting of planning permission as being the point at which their involvement switches to finances and choosing the finishes, fixtures and fittings whilst the rest of the work is taken on by the builder. Funding Funding a self build project can be a daunting and occasionally very complex task. HANSE HAUS partner Mary Riley Solutions have a wealth of experience within the Self Build arena and are able to expertly advise and guide clients through the process, coordinating the professional and financial service providers from A - Z of their build project. Foundations All sites will need a specialist soil investigation to determine the type of foundation needed. In most cases, your new HANSE HAUS will be built on traditional trench fill foundations. An independent structural engineer will need to verify all the information to Building Regulations. Whilst that is fine for the construction of the house itself, the reality is that there are a whole series of other activities on which the house construction is dependent. These need to be undertaken at the right time and in many cases, the right sequence. One can get a reasonable idea of how much time and consideration these activities might take based on how much of the overall project cost they account for.

The accessible ‘Belvita’ showhome was planned in collaboration with two disabilities consultants who are both wheelchair users themselves. The result of this collective planning process is an attractively designed bungalow that offers a high quality of life by meeting the needs of those with or without disabilities in every living situation. Customised solutions for happy, carefree living The daily lives of the disabled can be made easier through a wide range of detailed HANSE HAUS solutions. Not only does the accessibility design tick boxes in terms of living comfort for the disabled but it also allows those of advancing years to continue living in their own homes as they enter later life. Our recommendations during the planning of an accessible home include: Arranging all living spaces, bedrooms and a bathroom on one level, or alternatively installing a wheelchair-adapted lift, as can be viewed in our “Vivario” showhome in Mannheim, Germany or the “Cubico” showhome in Suhr, Switzerland. · Space for manoeuvre with wheelchair turning areas of a diameter of 140 cm · Doors and hallways with a minimum width of 100 cm · External doors without a threshold · A floor-level, wheelchair-accessible shower with shower seat · Wheelchair-accessible washbasin and handles on all sanitaryware · Wheelchair access to the house from the garage/carport · Durable floorings with low rolling resistance, such as laminate floors or tiles 30 Meeting Notes Checklist Plot suitability House design Proposed budget/quotes Timetables Planning permission Sampling in Germany Building Regulations Discuss other costs Site visits – During Construction & on completion Finance & Contracts Notes 31 HANSE HAUS, an expert construction partner for your custom designed home Your partner agent Parent Company: HANSE HAUS GmbH Ludwig-Weber-Straße 18 D-97789 Oberleichtersbach UK Contact: Telephone: 0845 658 9780 (local call rate) [email protected] www.hanse-haus.co.uk HH · 03/13 · Auflage 1 · XX.XXX · P24 Choosing the right construction partner means you avoid compromising on quality, service and reliability.
