japanese architects takeshi and yuka komada have extruded and carved a home and studio out of a single concrete mass. named for its curvaceous form, ‘frill’ accents the dense urban fabric of tokyo’s suburbs. the design began with a single serpentine line; as it progresses, spaces are enclosed. every corner is given a gentle radius, but some are carved away to create passages between the rooms. s one proceeds through the house, the perception of the disjunct interior changes based on how it is framed. looking along narrow corridors, the small dwelling seems spacious, but when doorways open to a solid wall, the volume becomes fore-shortened. unified by white concrete walls and square windows, the complex series of spaces informs different uses within the residential program.  on the ground floor, the large studio opens to the outdoors and can double as a gallery. upstairs, the bathroom is enclosed and encompassed by a hall that also functions as a library. off of this corridor are the main living and sleeping areas, and a stair leading up to the rooftop.

the first floor studio, opening to the back yard, can also be used as a gallery
