situated in a residential area of tokyo, away from the highrises and busy streets of shinjuku is ‘house Y’, a small dwelling on a corner site which has been conceived to accommodate two families. the exterior is composed of a 120mm thick shell of concrete, with the material applied on the interior as well, where it forms the 300mm floating structural floors which extendoff of a central foyer. this entrance hall serves as a communal area between both homes, while also dividing them. it has been openly designed so that the rooms of each residence–kitchen, bedroom, living and dining areas–situated on opposite sidesof this shaft, have views into the four-storey void. in designing the shared space, hiroyuki shinozaki architects wanted to make it ‘adjustable’,taking into account the changes in family life with each of the rooms having been made to increase in size.
