I thought that we should not create something completely new in the residential area where old communities still exist.The typical shape of house with aging paint on the outer layer made it as if it had been there for a long time.To create an image of everything is equivalent,OSB plywood was used for the floor,wall,and ceiling to have seamless space inside.Expanding corridors and the low ceilings high gave enough space to have rooms and to sleep at night.The house was created based on the residents’ life style,and the design allowed only 70㎡ to have 5 people living together just like a nest.
