accommodating enough room for two generations, the internal divisions of ‘house at komazawa’ by japanese firm atelier hako architects are stacked vertically on top of one another. sharing a common entrance and bathroom area, different ceiling heights help to define the separate spaces. the site is located in komazawa, setagaya ward, tokyo in a zone where single-family houses and apartments are mixed. the shape of the house is in response to the height limit of the building standards law, which made it necessary to have a slanting roof. the future of the surrounding environment is uncertain – in order for the occupants to be able to live comfortably without being too affected by any dramatic changes – the main openings are set up around the stairs as a buffer zone between the exterior and interior. in addition, the living area on the upper floor features horizontal, panorama windows that stream natural light across the entire room. the unusual size and shape allows for a level of privacy from neighboring properties and creates fragmented views of the outside environment.
