The Otake house is located in the West of Hiroshima prefecture, on a high plateau that neighbors the Kamei Park of the Kamei Castle Ruins. We created a design fitting to these two contrasting and beautiful scenes. We thought of the North side as the type of scenery you take in and savor, and the South side as the type that you place yourself in. By covering the entire building with water proof material used in ship construction we made a unique and detailed building that doesn’t require sealants or tiling. By considering views about execution from the planning stage on, we discovered water proof materials previously unknown to us. By rethinking standard practices and personal opinions about structure,utility,form,materials, interiors,and exteriors, we think we can find new possibilities for materials,the relationship of form and space,and the building and its surroundings, in a planning environment that opens up new wonders not found in traditional buildings.
