The already existing structure of the bank was extended by adding an elevated annexe acting as an office space. A seemingly floating sail facing the sun was also constructed, providing space for photovoltaic elements (32 kWp). The ensemble of old and new fits into the market town’s centre with ease. Even more so, the urban space can now be taken in easier due to the new elevated construction built alongside the road. Moreover the elevated annexe creates an areaway that invites social interaction and communication. For the outer walls, the ceilings, the roof, well as all constructive elements of the annexe, wood was used. Furthermore, the wood stays visible both on the inside and on the outside in the building’s weather-protected areas. This allows the architectural technique to be taken in by the general public. The street facing façade will be covered with by vertical greens – wild wine – during the warmer seasons. This will not only affect the building’s visual impact but also improve its microclimate. A construction reminiscent of a sail, which is attached to the roof ridge, not only acts as a photovoltaic system but also creates a weather-proof and light flooded pathway leading to the market square.
