Interior Space and Exhibition Design Tranquility Residential Space by CHEN HUNG-CHOU Chang Kai-Hsien Lights is a residential interior design for a five-story house in Taiwan shared by three generations. Each floor is planned around the taste of its users. The first and second floors use the high ceiling and large windows to create a bright and spacious area for guests. The third and fourth floors hold bedrooms in a simple style with industrial details. The fifth floor is a studio and display area finished with oriented strand board for sound isolation. A new spiral staircase, lit by LED lamps set behind the steps, connects all levels. Natural wood and marble are used throughout.
