Casa 3S is located in Austria. One of the main ideas was to incorporate the natural surroundings into the rooms of the house, which is why the design washes away the frames between the house and the garden, creating the intersections of light and a large open floor plan of the house under a flat roof. The shape of the roof is designed to create a terrace that looks very unique. The interior is kept in a modern and minimalist style; The walls are painted in light colors, mostly wide, to make the room look bigger. The rooms are not really separated in order to achieve the same goal. The materials are mostly natural and environmentally friendly. The house looks very modern and comfortable.
