The first passive house (Minergie-P) in Switzerland that has been realised using Steko is located in Neunkirch / SH. The stately, traditional single-family house has got the highest possible heating insulation value (u value 0.13W/m2K). The exterior wall construction is insulated with 160 mm Steko, outside further 220mm wood fibre insulation have been added in two layers. The wood casing and the partial plaster panels on the outside work as weather protection. In addition to the high insulating value particular importance was placed on outstanding air tightness.
The passive house standard (Minergie-P) requires an autonomous building concept, which is orientated towards the low energy use. The new standard Minergie-P means high requirements regarding the comfort offer, the economical value and the aesthetics. This is because the required comfort also includes the good and simple operability of the building or the technical installations. The following five requirements must be met:

• specific thermal output requirement
• thermal heat requirement
• weighted energy benchmark heat
• air tightness of the building skeleton
• domestic appliances

The architecturally successful single-family house was built using the Steko construction. The interplay of the plastered building parts and the wood cladding, which is painted in light blue, gives the house specific suspense. The simple roof form of monopitch roof and flat roof is reflected in the generous interior. The design and execution are from the architectural office of Sandro Imbimbo in Gerzenbach.
The company Mader Holzbau AG, which is located directly near the new building, erected the wood construction in 2003. The good collaboration of the planners and executing companies involved paid off in a smooth and fast building process – to the delight of the principal.

Since 2002 the house, which was built in 1981, has been a two-storey building with a fully developed roof storey. Only the surrounding parting line in the plaster between the ground floor and the upper floor indicates the different walls, which are behind.

The architectures D. Guex-Joris and M. Tasnady, Meilen with their special interest in Feng Shui developed a creative solution using Steko. The elegant roof arch, which is also visible in the interior, allowed for a roof story, which can practically be used as a full storey due to its shape.
The former roof storey was dismantled to the ceiling of the ground floor, which remained occupied during the entire building process. The carpenters of the company Stamm Bau AG then erected all exterior and interior walls using the Steko module system.

In Greenland STEKO is used for buildings.

„Grönländisches Familienhaus Jahr 2000“ was the title of an architectural competition in the Nordic countries. The architects Schmidt, Hammer & Lassen from Denmark won this competition with an ecological, economic and artistically intelligent and exemplary project. The modular Steko wood construction carried out also meets the high requirements in extreme climate regions. The floors, walls, ceilings and roofs were pre-fabricated and mounted in the shortest time possible.

STEKO holds its ground in extreme climate regions and against the strongest international competitors.

The design of the house of H. Schmid in Schaffhausen emerged in the workshop of the architect Patrik Jeuch. The lines in the interior of the house are continued outside. Due to these shapes flowing transitions from interior to exterior emerge..

On the ground floor the Steko walls are clad with plaster panels. On the upper floor the Steko modules remain natural. Together with the suspenders and beams of laminated timber they show the clear bearing structure of the building. The building was erected in the winter/spring 2000.

With their house high above St. Gallen and Lake Constance family Kühne demonstrates that a house can be particularly attractive and modern in its building and décor not just on the outside but also on the interior. Their Steko house was planned in the architectural office Frei & Gmünder, St. Gallen and was built in 1999.
The Steko walls are visible and varnished in white so that the wood grain is still clearly recognisable.
The inserted cube in the roof floor with its sheet façade is clearly distinguished from the remaining façade of a vertical, red casing. The sustainable energy household is achieved with the well-insulated exterior skin and the sun collectors on the southern roof.

Above the village centre of Beringen on a steep hillside there is the Steko house of the family Widmer. The architectural office Reich & Bächtold, Schaffhausen was responsible for the design.

The overall responsible entrepreneur was the wood building company Vögeli AG, in Göchlingen, which can already look back to successful and manifold experiences with Steko.
The light exterior and interior cladding and the large window areas allow for a lot of light coming into the building. The access to the house via the road is from the upper floor. The garage is located above the kitchen. A relevant roof construction of wood prevents the sound and oscillation transmissions.

A well-insulated wall construction with a u-value of 0.22 W/m2K helps to save heating costs.

This house was built in 1999. The architectural office Reich & Bächtold developed this house. The light-blue areas of the façade are horizontal upend casings. Plywood was inserted in the pediments. The colouring of these plywood boards is continued with the windows and doors. In the interior the walls are mainly plastered. The bottom ceiling and roof views are of large visible three-layered panels.

As common with all Steko houses this house stands out for its above-average heat insulation. In the winter the solid Steko wall works as a heat reservoir for the warmth, in the summer it keeps the room pleasantly cool. In connection with the high, generous rooms an incomparable and healthy living climate has been achieved.

Single person and two-people households are the trend. Why not design a house for that? Ruth Schwarzenbach, an interior architect, personally realised her own idea. She lovingly calls the two houses "Einerkiste" and "Zweierkiste" (one-person and two-people box). Discretely and still a unit the two "boxes" are attached to one another.

Despite the small exterior measurements of the house the rooms are generous due to the clever room partition. Daylight floods through the wall-high window areas into the bright rooms. The view from the living room through the window areas into the garden with seating and a pond allows for the holiday ambience to develop.

For the minimum energy house Reich in Salez only the renewable energies sun and wood are used for the generation of heat and warm water. The two buildings have got a volume of 1,250m3 and are equipped with controlled ventilation with heat recovery, which leads 80 percent of the exhaust air heat back to the house via fresh air. The sun collector area of 24m2 on the roof is also part of the sophisticated energy concept of the house as is the wood stove with heat exchanger and a warm water reservoir with an integrated boiler of together 3,170 litres in contents.
The good heat insulating qualities of Steko are effectively used. The vapour diffusible wall consists of the Steko modules filled with cellulose and an exterior insulation of 12 cm in thickness.
Ueli Rhiner, an architect from Zurich is the planner of the Salezer Steko house.

At 1800 m above sea level in Arosa there is the Steko house of the architect Georg Pfister from Zurich. The engineering office Josef Kolb AG, Kesswil, which disposes of huge experiences in calculating Steko buildings, had to consider huge snow loads. In order to increase the load bearing capacities of the Steko walls solid wood thresholds were used.
The exterior appearance reflects the traditional Bünden building style in combination with new elements and materials. The window chucks that are wide open towards the outside are very typical. The façade cladding consists of three-layered treated larch panels, which have been laid horizontally.
Despite the extreme climatic strain the vapour diffusible wall construction has stood the test. This is a reference object for the good building structural qualities of the Steko wood building system.

Right in the centre of the town St. Gallen there is an extraordinary Steko wood house. A long, narrow cube, slightly trapeze-shaped in its floor plan it is well embedded in the difficult basic conditions. The plot is narrow and steep.

The horizontal direction of the long walls is emphasised with the lying, open larch casing and the long window areas. The roof is greened. The object is a classic example for the modern architecture in wood construction. This also includes the use of the most modern house technology. The house, which has been designed and planned in the architectural office Haas in Arbon, demonstrates new perspectives in today's urban apartment construction.

Art and architecture

Modern and open is the exterior appearance of the single-family dwelling of the family Niklaus in Gächlingen (CH). The house was built in 1997 and is thus one of the first Steko buildings.niklaus1
The house was planned in the architectural office Reich & Bächtold, Schaffhausen, where many other Steko houses were built and which now disposes of huge amounts of experience.

Generous window areas in the southern façade allow light and warmth to flow into the outstandingly insulated house. The horizontal wood casing has been treated with a yellow, bright colour. Within only 2 days the wood construction was erected.

For years, one of the first Steko buildings has proven the good qualities of Steko.

The Villa Schmidhalter is located high up in the Swiss winter sports centre Crans Montana. The huge snow loads mean particularly high requirements regarding the load bearing capacities of the construction whilst the extreme climatic conditions presuppose the impeccable building structural qualities of the wall and roof constructions. Both requirements could be met perfectly using Steko.

The house with its chalet style was planned in the office Schmidhalter & Pfammatter AG in Brig. The Steko walls were kept visible in the interior. The façade consists of a crude crown-moulding casing of larch. The large porch is typical for the building style in the Swiss Alps. The carpenters Hermann in Albinen erected the house in 1997. It is remarkable how quickly Steko also appealed to people in such a traditional wood construction area such as the Valais Ð a chalet in Steko construction

.

Interesting combinations of materials and colours characterise the semi-detached single-family house, which was built in 1997 and planned in the architectural office Frei & Gmünder of St. Gallen. The façade consists of blue, back-ventilated, cement-bound wood chipboards. The roof clearly distinguishes itself from the building skeleton. The simple, modern architecture is expressed recognisably and at the same time brings advantages for comfort and budget.
According to the ecological, sustainable construction no oil is used to heat the house, but only wood.
