Interior Space and Exhibition Design Low Key Luxury Residence by Wei-Li Chen Low Key Luxury is a residential interior design for a duplex apartment of 165.2 square meters in Taiwan. The layout holds four rooms, a living room, a dining room and four bathrooms for a family of four. A long foyer acts as a buffer zone and features a marble wall edged in titanium plated metal, with built-in shoe cabinets and seating. Wide openings between areas let natural light reach the far end of the space. Wood flooring, layered grilles and warm autumnal colors create a calm and modern home.
