BLÄSIRING, BASEL, 2025
The objective of the vertical extension at Bläsiring 15b was to carefully densify a heritage-listed ensemble while preserving the commercial use of the ground floor in the inner courtyard. In close coordination with the heritage conservation authorities, a concept was realized that made the preservation of commercial use a mandatory condition to counteract displacement by residential space.
Amidst the green courtyard setting, the existing structure was complemented by a timber-frame extension and a delicate layer of balconies. As we carried out all timber construction work ourselves during the eleven-month construction period, this dual role as designer and craftsman resulted in numerous precise details developed directly on-site, while our continuous presence enabled close collaboration and direct exchange with the other trades.
