What are like one-storied houses in the center of urban cities? The surroundings and privacy matters, or how to use the outer space of the house. We pursed simplicity and richness the most. By decreasing the number of the rooms as many as possible, we made it possible to use the other space as rich and spacious materials. Furthermore, take away unnecessary stories,and take in the natural sunshine instead. This house is designed for a retired couple, proposing a new style of one storied house, which is located in the center of Osaka city. There is a concern about "eye" from the park and the apartments nearby, or "eye " within the site to the outside buildings. We solved it by proposing to encircle the entire house with wall. You could see a beautiful color contrast in green from planting within the site and in blue from the sky. We created a s-lined garden across the house, as you could enjoy it anywhere, and it is as if you were in the forest, watching a river(garden) running ! This one-storied house, which is surrounded with lined-up condominiums, has created a new concept of richness, in the concept of no need to be chained of thoughts that how large the ground space is, or how convenient it is.
