Redesign in the heart of Thun
Bälliz, a picturesque island between the Inner and Outer Aare rivers in the centre of Thun, is about to undergo a major redevelopment. Four historically valuable properties are at the centre of the project.
Bälliz, located on the south-western edge of Thun’s old town, is home to four properties owned by the Frutiger Pensionskasse. Despite their poor condition, these historic buildings are worth preserving and some are still rented out. The special significance of the Bälliz area is reflected in its inclusion in the ISOS Federal Inventory, which characterises it as a site of national importance. As a result, its characteristic structure must be preserved as far as possible.
Previous challenges
A feasibility study carried out in 2015 was rejected by various federal commissions. A new five-storey building was particularly controversial. In response, a workshop was organised to define new guidelines for the development of the area and prepare a project competition.
A winning concept emerges
Several designs were submitted as part of a 2022 study commission. The team from Baumann Lukas Architektur impressed the judging panel with a design that ideally combined urban and atmospheric aspects. This design honours the historical structure of the region and shows respect for the typical belt-shaped parcelling. It integrates the main houses and outbuildings in a way that reflects the significance of the site. The ground floor will continue to offer areas accessible to the public, while the upper floors will mainly contain flats.
Diversity versus monotony
The design by Baumann Lukas Architektur stands out for its diversity. The design makes reference to the characteristic structures of the Middle Ages and provides for innovative developments, such as the public “Gässlihof”, which retains its authenticity by preserving a historic building. In contrast, other submitted designs were not as differentiated in their proposals and were not able to convince the judging panel to the same extent.
