Y house by Beijing Matsubara and Architects
This residence in Beijing by Beijing Matsubara and Architects was built around a smaller house that was already on the site.

Called Y House, the project involved encasing an existing two-storey house with pitched roof inside a larger three-storey structure to provide more space on either side of the old building.

The original pitched roof is visible inside the top storey with a flight of steps installed on each side.

The architects intend the clients to use the north part of the house, which has natural ventilation, during the summer and the south side, equipped with basic heating systems, during winter.

This is not a new construction but the renovation project of the old concrete structure house that was built 5 years ago.

We proposed the sustainable lifestyle using this largeness. In the summertime, habitants live at the north part of the house with natural ventilation.

In the wintertime, they live at south part of the house equipped with the basic heating system.

For keeping the comfortable inner circumstance, we do not provide the high-spec air conditioning for all interior space, but provide the minimum equipment for adequate place.
