This is a collective house for eight families, whose peculiarity being its depth-wise length (18m par household). There are three approaches derived from this length.
1:Long and curved walls make the air in this house so ambiguous and amorphous. In addition color of white on floors, walls and ceilings is useful for this image. Vacant air that is scentless and colorlessness is easy to get 'coming' atmosphere. The space is always waiting for transformation.
2: To make the 18m wall a 'continuous curved surface' so it turns itself into a device generating landscape. (=conceptual image, red) And painted mortar material of the walls emphasizes the 'continuity'.
3: To insert three exterior = voids along its length to the swelling part of curved walls(=conceptual image, green) * three voids pierce through four levels of the building * they also provide natural lighting and ventilation to the long, deep residences
Such approaches would realize a living space with a feeling in every room that the exterior is close and familiar, even with is the multileveled collective housing.
