A portable bathroom is a city furniture, which should be both an art-piece and a well-functioned, environment-friendly urban necessity.

However, how to create a portable city furniture that would suit not only the historical surroundings but also modern city districts? How to create a form which is not aggressive and responds to materials from the surrounding built environment, beyond the change of time and site?

My concept mainly develops from these two ideas. With research on the scale of the sphere and the network of the surface, the envelope turns out to be a sphere with a panoramic reflective surface. As well, the organic interior follows the exterior surface, covered with less reflective resin material.
