The task at hand was to build a 900m2 urban villa in Taichung. Taichung, a city where neon-lights and commodifications are so overwhelming, that one in fact would like to leave the plot untouched, have it be only a haven of calmness - a place to breath and retreat.The proposal - an indoor open space. The spatial experience develops through a series of indoor and outdoor atriums that are visually linked through the slits between the folding plates and physically linked through the gaps within the folds.The interior atrium is a living room around which spaces of various degrees of privacy are experienced, foyer - living room/kitchen -dining - reading room – bedrooms. The degrees of privacy are not defined with solid wall elements but with ones accenting positions - from the disclosures to the enclosures. The exterior atrium is a courtyard that separates the parents’ living quarters from the children’s - a request of the clients to preserve an appropriate privacy in the family. A conventional courtyard house is applied as a model of dwelling and flipped 90 degree vertically to fit into this long and narrow plot. It is a building of infinite circulations, a building of a plate folds down in segments to become ceilings then walls then split-level floors inside out and outside in. The split-level changes of these folding plates are what provide the complex viewing possibility weaving through this indoor open space, giving it its own internal referential reality, a reality that had composed a silent sense of belonging - home.
