The 'Wohn- und Geschäftshaus am Herrnstrasse' in the old centre has a strong interaction between opening and closing. Every second element in the floor-to-ceiling glazing is a sliding door. The anthracite-brown galvanized window frames give the inner layout a maximum flexibility - and together with the wave-shaped sunscreens, the building has an ever changing appearance according to the weather. On the roof top an intimate wooden penthouse is placed, with large windowsills, made out of oak wood. The underground car park can be reached by an auto lift.
