Large penthouse flat with bedroom, dressing room, study/guest room, two bathrooms, relax/gym, terrace, living room, open kitchen and dining room. Existing lift is extended up to the new penthouse floor. The stairwell’s stairs are extended up to the mezzanine joist.

Area: 196 m² + 15.5 m² (alt. 32 m²) mezzanine joist

In terms of area, a large flat with a relatively complicated space to make into a residential flat. A large portion of the load-bearing wood constructions need to be demolished to free up space and must be replaced with a less bulky steel frame. The existing wooden floor joists are not dimensioned for the housing loan seen from today’s norms. Our job is to ensure that the floor joists meet both load-bearing and sound requirements.
