This is a reinforced concrete structured house for a family of 3. This house was required to respond flexibly to changes of their lifestyle and the store they own. 

At two diagonally placed corners of the house, large wall pillars have built which seems to be out of proportion compared to the scale of the house. These wall pillars enclose private functions which doesn’t require big windows, such as entrance, bathroom, toilet, storage, and pipe space. 

The floors and roof outside of these wall pillars are not connected to additional foundation or pillars, instead they are cantilevered from the two wall pillars like branches and leaves. The wall pillars and slabs are in a relation like a tree trunk and leaves. 

The interior space has a straight circulation that leads to more private spaces as it goes further in. Just like birds hop between branches, this plan allows people to spend time wherever they want by moving between the pillars and floors. 

The two concrete wall pillars placed in checkered pattern and cross-sectionally displaced floors create a sense of distance. This let people to perceive the sense of “other side” from any room they are in, and this sense is extended to the outside by opaque glass of the exterior wall. While each room goes beyond its purpose and meaning by been interrelated with each other, it separates the whole space, and expands outside. It is a simple cubic building, but it is an architecture with rich interior space that has depth and an exterior that corresponds to it.
