Renovation of an apartment into a house for a family of four: a proposal to look for future housing

・A 21-year- old, two-story wooden quadruplex was purchased.
・The two households on the 90-square- meter second floor were joined and renovated into a house unit.
・The two households on the first floor were kept and continued as rental properties to secure income.
・A house unit was obtained in a short building period of two months at a low cost.
・A large 36-square- meter space was secured for the living room, dining room, and kitchen.
・The column was moved and a wide, open space with a ceiling height of 2.9 m was created with the exposed beams.
・Thermal insulation made from mineral wool was used for the floor, walls, and ceilings, and the windows were double-glazed for heat and sound insulation.
・Diatomaceous earth was used for the finish of the interior walls to control humidity conditions and for its deodorizing capabilities.
・The pale-green marble floor creates an impressive space.
・The exterior of the building was retained, with no renovation, to emphasize the difference between the interior and exterior.
・Apartments destined for “scrap and build” were converted.
