This is a renovation project in a plot facing a main street in Tokyo. The client had decided to renovate their aging residence and the project started.

The mission was to secure maximum space in this extremely small and oblong recessed site surrounded by 3 sides of buildings. We adopted massive steels for the fire proof and external walls without outer scaffolding.

The exterior symbolizes as a reversal of alphabet “S” . Part of the site is used for the stage of the Sansha festival and thus a bench is arranged at the root of pilotis. The annual fireworks festival of Sumida can be appreciated from the rooftop thus it is being planned to turn it into a green roof.

The interior sets a home elevator to assist the vertical slant in this extremely small area. The top floor lays a salon of 5m ceiling height to capitalize its core. Keeping favorable distance from the buildings and making maximum use of this of this extremely dense environment, both the interior and the exterior has many innovative characters. Although compact, the lifestyle with spacious and noble space would be in SERPIENTE.
