Edward Suzuki Associates design a prefab to bring the outside in
Xevo EDDI is an extension of EDDI’s House, the first case of an industrialised house in Japan (and perhaps in the world) designed by an architect and built by a major housing manufacturer, Daiwa House Kougyo, in a collaborative effort.
Pre-designed, pre-fabricated and sold as a ready-made 'product', the buyers' characteristics, lifestyles, site conditions, etc. are not known at the time of design. As such, the architect has opted to design under the assumption that the site on which the house would be placed is not surrounded by environmentally friendly conditions, as has been so proven more often than not through the architect's experience over the years, and that the house should look not outward but inward.
As a result, the design concept for a typical type is 'outside inside', meaning that the typical house has an outside patio at the centre of the house onto which each and every room looks out. Furthermore, a balcony is placed above and adjacent to the central patio overlooking it in such a way that this combination of open spaces creates an 'interface' between the outside proper and the inside that acts as a filter, a buffer, or a cushion between the two zones. In this way the design is such that the house does not need to depend on the contextual conditions in which it is to be situated. No matter how unfavorable the surroundings may be, the house would function comfortably within the mini-cosmos of its own boundaries.
The house, with its central patio, is designed to allow as much direct natural sunlight and cross-ventilation as possible to provide for optimal energy efficiency. Xevo EDDI now boasts 5 basic types of plans with 57 variations to accommodate as broad a range as possible of varying site conditions and characteristics.
