Bevaring og integrasjon av bygning

The project involves the comprehensive excavation of the economic part of the historic Bollingerhaus structure while preserving all facade walls except for the south facade. The existing natural stone walls were underpinned to stabilize them, and a new building, including a basement, was integrated into the area using solid construction techniques. The load transfer of the existing truss structures was managed via a new concrete floor.

Rekonstruksjon og isolering

Construction included the reconstruction of the residential part and securing of the vaulted cellar. Wood-concrete composite ceilings were built, and new perimeter insulation was added to the roof and walls, along with new exterior wooden cladding. The detailed construction services involved the assembly of wooden structures according to BKP 214 guidelines.

Bevaring av romersk murer

One significant challenge was the discovery of 1700-year-old Roman fort masonry and a defense tower during the reconstruction. Preserving the ancient entablature and ensuring new load transfers in cramped conditions without damaging the existing structure was critical. Additionally, elements were inserted while meeting fire protection requirements.
