Extra storey, Klarastrasse in Zurich

We used our modular construction system to add an extra storey to the existing residential building on Klarastrasse in Zurich, creating two new one-bedroom flats with balcony[JT1] . The work included extending the lift shaft into the additional storey. The two apartments are finished to a high standard, including large roof terraces measuring around 30 m² with wooden pergolas. Häring AG performed all the extension work as the complete contractor.
