Tokyo’s Yamazaki Kentaro Design Workshop recently unveiled House in Kashiwa, aka “Unfinished House.” This modern, flexible structure maximizes space while allowing ample room for creativity. The unit’s open floor plan is flanked on all sides by rectangular additions, each two stories high and divided into four cubicles. The center of the building serves as the natural meeting area, and lower level cubicles function as bedrooms, an office, and the kitchen. The upper cubicles have all been left untouched, so that the house's inhabitants can transform them using their own creative powers. This blank slate approach to architecture and interior design lets the owners really make the house their own.
