Description of project

The annex at the hotel Sarotla in Brand (A) consists mainly of two structures and a suitable connecting building at the existing part.

In the northern, 5-story construction component are located: an underground parking, a new reception, a lobby, a seminar room as well as 27 new rooms and a penthouse flat. Due to the hillside situation an underground parking (first basement floor) and a plant room (second basement floor) were built on the west side as solid constructions. A solid ceiling stretches over the seminar room on the ground floor. At the top of it the hotel room modules are situated on the first floor and on the second floor the penthouse flat is built as a cross laminated timber construction. On the east side four prefabricated hotel room modules made of cross laminated timber are stockpiled. The required fire protection posed a special challenge in the up to five floors high timber construction. The room structure had to be interrupted in the lobby area. Therefore, it was necessary to provide the room modules with load bearing shear walls, so the systematically arranged supply and disposal lines were not touched.

The annex on the south-eastern side contains the 2-story spa area with indoor swimming pool on the upper level and the spa (including plant rooms) on the lower floor. The roof is used as a terrace for the dining room.
