Situated in western Austria, the hotel consists of a heterogeneous accumulation of buildings of different dates. It was to be extended by a further bedroom tract with a hall for various events. Since the hotel is in use almost year round, a very short construction period was necessary. The solution was found in a series of prefabricated containers that could be stacked on top of each other. The 7.50 x 4.00 m boxes are self-supporting, so that no primary structure or additional bracing were required. Services were laid in the voids between the cells. Only the glass bathroom walls and the wood furnishings had to be installed subsequently. The boxes and roof were erected in two days, and after only a month, the extension was ready to receive guests.
