Renovation of Silvia Gmür's house in Riehen

In this building, completed in 1978 on a steep slope, the importance of the connection to the outdoor space is evident – a feature that would become a defining element of Silvia Gmür’s work.
The basement, constructed using solid masonry, supports a timber structure that is visible throughout the house across several levels. 
On the ground floor, the individual living areas flow into one another, creating a spacious layout that interlocks visually and spatially with the outdoor space in various places. Large glazed areas and skylights provide optimal natural light, as well as views of lush greenery or across the city of Basel.
The horizontal flow of space is complemented by an open vertical network of spaces. Voids, galleries and individual structural elements are highlighted, allowing for glimpses and views through, and creating a spatial complexity.

In contrast to the spacious areas for daily family gatherings are the more compact bedrooms and children’s rooms, which are intended more for retreat than for spending time in. 

The house was upgraded to improve its energy efficiency and refurbished in 2025. A PV roof with blue cells, combined with heat pumps, enables the house to operate as an energy-positive building. The interior has been restored in accordance with heritage conservation principles; the result is a timeless building that meets the latest energy efficiency standards for new builds without compromising its visual appeal.
