The house structure is a RC frame structure widely used in Vietnam. The partition walls are very few in order to keep interior fluency and view of green façades from every point of the house. During the day we get the varying light with the time of day trimmed by the top-light in the center. In the morning and the afternoon, the sunlight enters through the amount of leafs on both façades, creating beautiful shadow effects on the granite walls, which are composed of strictly stacked 2cm stones.
