This thesis is aimed at formulating a theory of the generation of rectangular single storey house plans using minimum space standards. Its purpose is to eliminate unused space in the design process in order to generate a range of house plans from which architects, planners or future occupants might make a selection appropriate to specific needs. In this study theoretical and methodological aspects which underlie the establishment of a quantitative area/dimension relationship are investigated. Generally in rectangular geometrical arrangements, problems arise in architectural design in the fitting or packing together of rooms into a plan within a certain range of shapes and dimensions. These problems are further complicated by the need to satisfy within the geometrical arrangement, certain required topological relationships between rooms. The method places emphasis on two aspects; first, the interdependence of minimum room dimensions and house plan for different family sizes and with varying degrees of functional segregations; secondly, the possibility of a change in the occupant's requirements necessitating flexible room arrangements or the adjustment of the size and configuration of the plan to arrive at an optimum solution. The investigation takes account of important cultural differences between the U.K. and Korea. It is possible to derive the overall plan outline - the shape of a building's perimeter - in two distinct ways. Either the building is designed from the inside outwards, rooms are aessmbled according to specified criteria, so that the final building shape is merely the end result of this process. Or else the external form of the building is determined first on quite different grounds, and then, like an empty container is filled up with rooms. In this thesis, I considered systematic generation of the minimum space, standard house plans in conjunction with the above two approaches.
