Description of project

The former hotel was redesigned to serve as an apartment house after the alteration and attachment of new building parts.

We had to analyse the complete existing structure in order to achieve the merging of rooms with as little investment as possible.

A special challenge in a structural point of view was the evaluation of the existing structure to find out, which load capacity existed so that the reinforcement measures could be calculated and planned accordingly. All floors and the roof truss were part of the modification.

Furthermore the building was expanded on the south-west side with a carport, which consists of exposed concrete. Beside its regular utilisation this car park works as a retaining wall against the superstructed slope behind it. The carport consists of eight parking lots, a storage yard and a stairway leading to the main building.

On the north-east side of the existing building a subterranean extension was built, which contains a woodchip storage, a laundry, a boiler room and a garbage room. The excavation support was another challenge, as there was hardly enough space for batters. However the local situation demanded a batter of about 6 m - 7 m height. We solved the problem by using excavation sheeting, which was made of a shotcrete nail wall and temporary ground anchors.
