Interior Space and Exhibition Design Profoundness of Structures Residential by Chong-Yi Chen Profoundness of Structures is a five-floor residence and art exhibition space in Tainan, Taiwan. Architectural grilles bring daylight and fresh air into the house and help control the indoor temperature. The grilles reduce the heat absorbed by concrete structures in the subtropical climate and save energy. Fair-faced concrete, steel, wood and track lighting form a minimal interior that highlights the paintings on the walls. Grass pavers at the entrance improve the water retention of the soil. A fish pond and a corridor of terrazzo and cobblestones create a natural setting.
