The client intended to build a 3-family house with an annex for garages and recreation room. The upper two floors should be able to be used as an apartment for some time.

A two-story addition was planned on top of the existing building of about 20 x 25 m floor area. The existing building - an approximately 30-year-old object with a flat roof consisted of reinforced concrete columns in a grid of and 3 x 5 m and glulam beams placed above.

The tithe barn was one of the oldest preserved buildings in the city of Thun. After a fire in 1999, it had to be renovated in cooperation with the preservation of historical monuments of the canton of Bern.

The municipality of Oberlangenegg decided at the beginning of 2000 - it was the time when Lothar raged - to build this project in wood. With a supply center that should be deliberately dominant and quickly recognizable, Schwarzenegg gets a village center that represents and enlivens the village image.

At the parent farm, a replacement new building in wood was created, which, in addition to apartments for the younger generation, should provide additional apartments for the purpose of sale/rent. In addition, 2 apartments are used as a retirement and nursing home group.

The existing building in the center of Thun was converted into business premises and apartments. On the 1st floor, three high reinforced concrete girders were installed, which protruded from above about 70 cm into the clearance gauge. The planned store was to be column-free with a smooth soffit. The existing beam layers were to remain unchanged.
