This project was a renovation type for an apartment in the heart of Tokyo. The client's request was to have 3 existing rooms: 2 bedrooms and an enclosed kitchen combined into one spacious room as LDK. The combining of the rooms was not a challenge, the challenge was how to deal with the now too spacious a room to feel the intimacy of the space. What I did was consult the ceiling to help create temporary territories. The new big space is for living, dining and kitchen; I therefore had 3 light enclaves (what I call the bubbles) in the ceiling that would help define the 3 function elements of the room.  These bubbles about 1.2m in the longest side are visible from any corner of the house. They therefore act as space definers and also as softeners of the rigid architectural walls.
