UBS «Anfos»
Urban development in Solothurn
The site at Zurmattenstrasse 34, 36 and 38 in Solothurn is noticeably underutilized and has potential for urban development.


The UBS «Anfos» real estate fund is therefore planning to erect two new buildings on either side of the existing high-rise. The project will not only double the living space, but also improve the quality of life and energy efficiency in the development. A corresponding project has been under development since 2020, which forms the basis for a new design plan. Participation in the project began in mid-August 2024.

For years, the neighboring plot of land was reserved for the planned “central western bypass”. After the road construction project was abandoned, UBS «Anfos» was able to take over the additional area, which consequently became available for neighborhood development, with a 10-year purchase option.
Housing supply almost doubled

The plan is to build two multi-family units to complement the existing high-rise, which was completely renovated between 2008 and 2010. This will nearly double the current supply of just under 60 existing apartments. Consequently, the two existing single-story buildings will be demolished and the underground parking garage will be expanded on the site where the new buildings will stand. The new construction will include two new four- and five-story buildings with over fifty new apartments, including numerous small apartments.
This will leave plenty of open space and green areas despite the densification. The start of the construction project is planned for 2026.

The new buildings will be equipped with a sustainable heating system, based on renewable energy, with solar cells to generate electricity. The open spaces across the entire area will be renewed and planted with numerous native trees and shrubs. A new playground is also planned. The improved walkways and greenery create added value for the residents of the entire area, as the green spaces are more accessible.
