kubo tsushima architects renovates and extends ‘edoyu’ spa in tokyo – Designboom

kubo tsushima architects has renovated and extended edoyu, a spa and bathhouse facility in tokyos kamezawa district. as the site is located in close proximity to the sumida hokusai museum an institution dedicated to katsushika hokusai the design of the spa is inspired by the work of the famous artist. while staying true to hokusais world, in our design, we also tried to emphasize the concept of the word yu in edo-yu, which means freely wandering and enjoying, explains the design team.

externally, kubo tsushima architects added a faade to the building that is reminiscent of bathhouse curtains blowing in the wind. this entrance to edoyu is made up of four tall aluminum panels that hide the junction between the existing building and a new annex that doubles the spas floor space. the panels have been punctured with a seigaiha pattern that gradually disappears as the elevation ascends. passing through the curtain-like faade symbolizes the transition from the city to the spa retreat.

thanks to its reinforced concrete structure, the annex has no columns or beams. this gave the architects more freedom in determining the interior layout. we designed small spaces through the use of bathtubs, furniture, finishing materials, ceilings and differences in lighting environments all so that they would form a continuous sequence, says the design team. although the spa can accommodate up to 400 visitors, the architects designed the spaces so that all guests can find their own private areas.

the womens bathing area has been designed to evoke the feeling of floating in the clouds. the tubs are set at different heights, while apertures cut into the ceiling take the form of clouds. other areas of the scheme, including a co-working space and a restaurant, are contained within the previously existing building. while our inspiration derives from hokusais world, our goal was to construct the edo world from a modern, or perhaps even near future, perspective, say the architects. read our interview with hideaki kubo and yumi tsushima here.
