Nope, I'm not blogging about another tree house, instead this is a grounded residential home named Tree House, by Mount Fuki Architects Studio. :)
On a hill in northern Tokyo, Tree House sits on a site that is completely encased by the adjacent homes. The two floor levels spiral gently upward, around a central “trunk.” The resultant differences in floor and ceiling heights define the different uses of the home’s space, which draws its form from the quadrant format found in traditional Japanese homes. For example, the darker area with the lower ceiling is for sleeping, and the bright, high-ceilinged area with a large window is for dining. On the second floor, the spiral allows for large windows for the loft space, roof terrace access, and a view of the open sky to the east, as well as of a neighbor’s greened roof.
