The Mirror Window

The Mirror Window is a minimalist interior design located in Tokyo, Japan, designed by Kosaku Matsumoto. A partial renovation of the office area within a building complex that hosts a workshop space, an office, and a contemporary art gallery. The project was completed after designs and constructions made during three months of the architect’s on-site residency. The existing window with the dimensions of two by two and half meters – the first sight for visitors as they enter the space – had a barren view of an adjacent house. It was clear at first glance that changing this window would determine the nature of the new space. The idea was to abandon the use of this window would determine the nature of the new space.
