The project
The basement and first floor are built in cast-in-place concrete, the three upper floors above are pure timber construction. The supporting structure consists of beech columns and beams with solid spruce ceilings above. In the roof, a truss was formed with the beech girders, which dictates the shape of the roof. Insulated hollow box elements are stretched over the trusses. A back-ventilated wooden formwork forms the facade cladding. The stairwell and elevator shaft walls were constructed with CLT panels. The slabs are all formed into slices, which transfer the forces from wind and earthquakes into the bracing walls. The stairwell and elevator core walls, as well as individual exterior wall elements, were used for bracing.

The construction
The columns and beams in beech (grid 4.0 x 5.0 m) with spruce solid wood floors above allow for an economical and efficient construction method. The supporting structure also immediately forms the visible surfaces inside the building and gives the building its own character. The three-meter cantilevered canopy was created using a TS3 CLT panel (wooden panel supporting in both directions) and suspended from the building with tie rods. The same type of construction (TS3) was also used to create the roof for the container spaces, which is supported at certain points.

The challenge
The three upper office floors are connected to each other via an open area inside the building, so that an RWA (smoke and heat exhaust ventilation system) had to be planned. A fan in the roof will extract the smoke gases in the event of a fire.
