A penthouse in a St. Moritz apartment house is to be converted into an Engadine residence. The result is a cozy and elegant ambience with a strong relationship to the Engadine. A pine wood ceiling from an old ''Engadinerhaus'' in the dining room and antique chairs from the region harmonize.with new pine wood elements. In the living room a lounge was placed around the fireplace, which is slightly lowered and nestled into the floor for more comfort and warmth in the spacious light-flooded room. The level difference in the open space structures the room well. The bathrooms were built with rough Luserna stone slabs. A backlit wall construction designed by Küchel Architects, a wooden lattice made of thin slats, creates a special light play in the entrance areas.
