Interior Space and Exhibition Design Casa Calma Residential House by Paradox Studio Casa Calma is a residential interior design for a three-generation family. The home covers 360 square metres on one floor, with two private elevators at the centre and windows on four sides. A double-height terrace faces the mountain view. A 2.8 metre tall rotating door divides the plan into two areas, so the bedrooms can be closed off from the living room when guests visit. During private family time the house can be circulated as a loop. Mineral coating and a bronze-toned ceiling line guide daily movement through the space.
