First stage Attisholz with UBS investment
Mit der Pensionskasse der UBS als Investorin steht die Zukunft des Attisholz-Areals fest. Das historische Gebäude «Kocherei» wird in Zusammenarbeit mit der Halter AG zu einem modernen Wohn- und Geschäftsgebäude umgestaltet, ein entscheidender Schritt zur Entwicklung eines lebendigen und nachhaltigen Lebensraums.
The Attisholz site in Riedholz is being given a new lease of life thanks to an investment by the UBS pension fund. The “Kocherei”, once a central location for cellulose production, is being extensively remodelled. The winning project by Burckhardt Architektur from Basel envisages around 150 rental flats and 4,000 m² of commercial space, which will breathe new life into the historic building.
Collaboration between UBS and Halter AG
The UBS pension fund, which acquired the 73,000 m² core site back in 2022, has now also confirmed its investment in the “Kocherei”. A work contract was signed between the UBS pension fund and Halter AG on 28 June 2024. While the UBS pension fund will act as investor and owner, Halter AG will be responsible for the planning and realisation of the project as overall provider.
First stage of the site development
The development of the Attisholz site, which is to be transformed into a sustainable living space over the next 25 years, begins with the first stage. In addition to the “Kocherei”, this also includes the “Lagerhaus” and publicly accessible open spaces. The design plan for this first stage is currently being drawn up in collaboration with the municipality of Riedholz and the canton of Solothurn and will soon be submitted for public consultation and approval.
Sustainable and vibrant future
The transformation of the Attisholz site into a vibrant and sustainable neighbourhood is an important project for the region. The revitalisation of the “Kocherei” and the creation of residential and commercial space are central components of this vision. The realisation of the projects is planned for the period 2025 to 2028 and will contribute significantly to the upgrading of the entire area.
With the UBS pension fund as a strong partner and Halter AG as an experienced developer, the transformation of the Attisholz site will be driven forward swiftly and professionally in order to create a new, sustainable living space for the municipality of Riedholz.
