Planning contract
Engineering of the timber structure, including development of details and execution of design.

Project description
The Wisdome is an extension of the Tekniska Museet in Stockholm, with an innovative free-form roof. Due to sponsorship, the main material for the timber structure was LVL and CLT from Stora Enso. The roof structure is a bent-on-site timber gridshell, constructed out of five crossing layers supported by pre-tensioned timber columns and spans with a maximum lenght of about 47 metres. The layers each consist of five lamellas of LVL, which were bent info shape on site and held in place by wooden dowels and screws, enabling loads to be transferred via contact. Another part of the Wisdome project was the inner dome, which has a diameter of approximately 20m, is completely made of CLT panels and will house a 3D cinema.

Project description
In a private Indian home, the free-form timber structure stands in an atrium and supports a custom-made glass roof. Due to the elliptical leaves, it appears as a sun-flower with dimensions of approx. 15.00m x 7.80m.
The structure is made of steam bent ash glulam beams to meet the high aesthetic requirements.

Project description
The new headquarters of the watch manufacturer Swatch is located in a kite shaped 11’000m2 facade, which is supported by more than 2’000m3 free formed glulam beams. The beams were already formed into their individual shape during the gluing of the lamellas, which significantly reduces the volume to be cut off.

Project description
In urban space – close to the port – an up to 7 storey high office building in timber-frame construction method emerged. The joints are put together with wooden Baubuche-dowels. Impressive is the atrium-like inner courtyard (Lobby) with swung staircases which are also made out of wood. The stability of the building is achieved through 4 central service cores made out of concrete. The building has an extinguishing system and the fire resistance of the structure is 90 minutes.

Project description
The curved roof shape is resting on top of 24 single columns with spans from 6.6m up to 12m and is „floating“ above the building. At the, to the coast pointing front facade, the roof structure is cantilevering 5.5m beyond the
building. The roof surface measures about 26m x 62m in plan view. The bearing structure consists of primary beams made of beech and oak wood with single-curved secondary beams made of spruce wood spanning between the primary beams. A highlight is the partly double-curved edge beam made of oak wood enclosing the roof.

Project description
On Seine-Island there is an outstanding concert hall with a shell of wood and glass. The freely shaped wooden supporting structure measures 45x70m and spans freely up to the roof at a height of 30m. The glulam blanks were glued in 3-dimensional curves and all surfaces were precisely milled over with NC technology. Settlements in combination with brittle structures such as glass are an enormous challenge for concept and dimensioning. At the same time, architect Shigeru Ban demands connections that are as steel-free as possible.

Project description
As part of a research project at ETH Zurich a new type of roof construction was developed. As a result, individual, small beams were laid with a robot to form a framework and nailed together. This meant that each beam could be joined together in a slightly offset manner, resulting in this full-surface supporting structure and undulating roof.
