To increase the number of guest rooms at Hotel Wilder Kaiser, an expansion of the dining hall was required. In addition, the dining hall was supposed to provide a direct entrance. Internally the new building had to form a unit with the main house while maintaining its autonomy. The look of the existing beech doors, fixtures and furniture was continued in the new building in a modern way, by using BauBuche. The different beech wood surfaces meet in the dining hall to form an exciting new unit.
