Architecture and decor in the project by Fritz Haller in Solothurn


The origins of the USM modular system are reflected in this house built in Solothurn in 1976-77, commissioned by Edith Hafter-Kottmann to Fritz Haller, who took inspiration from the “mini-construction in steel” of the USM systems, in an adaptation of the Maxi, for the construction of single-family homes, pavilions and ateliers.

After light refurbishing, the architecture firm Branger moved its headquarters here in 2015, and today the 450 square meters of space host a team of 20 people.

Just as forty years ago the system offered a combination of modern works of art, antiques and USM Haller furnishings, today the geometric structure of the house is reflected in the modular composition of the shelving and tables by USM Haller.

Branger has not only conserved the history of the house, but has also expressed a sense of continuity in its furnishings. The basic structure of the building has been restored, and to some extent reconstructed, together with new portions. In the structure the materials and colors correspond to the white and pale gray of the USM Haller shelving, and the pearl gray of the USM Haller laminate tables, with panels, supports and a suspended ceiling.

The black USM Haller cabinet, in a central position, generates the first impression: it embraces the base of the staircase, recreating the U-shaped form of the upper gallery that frames the space at the center of the ramp.
