ARII IRIE architects crowns japanese house with elevated roofs in hamamatsu

this private residence by tokyo-based ARII IRIE architects is located in hamamatsu, a city on the southern coast of central japan known for its warm climate. the house is a detached extension of an existing one built in 1983. through this project, the studio aims to create one whole building structure, bringing old and new together rather than emphasizing the contrast between the two.

ARII IRIE architects has conceived a familiar wooden construction in a rather unfamiliar manner. linear volumes are stretched in the east-west direction, spread over the site, leaving spaces in between which are the terraces and gardens. meanwhile, an elevated group of roofs relate to the existing house configuration, creating a sense of continuation. indoors, sliding windows and doors are found in between furniture units and can fully open — thus connecting the detached interior spaces with the original house. the roof is lifted up with beams, making the indoor somewhat like a covered outdoor space.
