Tokyo and Hiroshima-based practice NAF architect & design have recently completed Glass House in Hiroshima, Japan.
“This building is based on a simple system to stack large concrete blocks of 1.0 mx 1.0 mx 1.5 m as building blocks on top of each other to get a structure with a large wave as breakwaters or wave absorbing blocks. These large concrete blocks manufactured at a cement plant in Etajima city, Hiroshima, at a very low price as excess cement is re-used and often used for surface retaining wall or anchor on rafts of cultured oysters.
Total composition of the house consists of the roof and clear glass to enclose the interior space with the aforementioned concrete block structure. There is no roof over concrete blocks. Therefore, the sun’s rays pour over the blocks, and reflection of light shines inside the house. In addition, the vines of flowers planted along the block, change the breakwater-like structure to a hill flowers and greenery in the future. Mass of stacked large concrete blocks are too large as a structure of a building, and the silhouette is far from ordinary. The building also has a feature of the landscape that controls the wind, light, and green, leading these factors decor and give freedom to the inner space that exceeds the form of conventional architecture.“
