Japanese studio ON design partners has recently finished the private residence titled 'what categorizes the city and me' in chofu, tokyo, on the threshold of a dense park with a small shrine. the archetypical house typology in section is divided into a mosaic of stacked spaces, extruded to create shelf-like structures that are completely open to the front and back of the house, forming a slightly differing relationship between the user and the town in each room.the entry level is set below grade and contains the studio and coat room, with access to the back yard. the first floor has a bedroom, kitchen and a section characterized by tatami mats. the final storey is a mezzanine level looking out over the kitchen area and houses the children's room, with access to the rooftop terrace. the structure consists of stacked masonry concrete block, beveled at the ends and capped with large glass panels that show the delineation of each room on the exterior. the interior is coated in smooth neutral-toned plaster contrasted by dark wood floors, wall panels, and furniture.
