This is a residential and office space is created by Eastern Design Office which was completed in Takarazuka, in the Hyogo prefecture of Japan. The development takes the full advantage of the sloped, 330 meters high hill by not flattening it. This results in a beautiful view of the breathtaking Osaka plain from the perspective of the building. The foundation is raised, 15 meters-deep hard bedrock that creates two heaps of soil. This makes it invisible from the upper side of the road, affording a privacy. The design area is on the upper story, right above the residential area leading to the entrance and the main road. Eastern explains that the main theme is something like the beginning of voyage of a ship across wavy oceans. What you get from being inside this architecture is some feeling of floating ship deck. The L-shaped floor accentuates the protruding edge to a large degree from the slope which is cleverly hidden to the settler by structural columns and walls.
The framework of the upper floor is of steel while the first floor is constructed of reinforced concrete. This has enabled the upper floor to serve as something like a deck that “floats” gently above the slope. Design by EASTERN Design Office
