Abstract
This study aims at analysing the relationship between housing and external space on the basis of Le Corbusier's houses and his 'Five Points of a New Architecture'. As applications of the external space in housing are diversified, the boundary becomes unclear and the external space alters ways of using the internal space. The transformation of housing style that was set off by social problems from the start of the modern architecture enhanced the roll of the external space in housing. The technological improvement at that times increased the relationship between living space and light, ventilation, and the outside air. The premodern housing style that had separated the internal space from the external by walls was overcome in the modern housing transformation. The Five Points of Le Corbusier had a great influence on history of architecture and became a basis for the transition into the contemporary housing. By analysing the Points in regards with external space, the followings will be understood: the background of the interpenetration of the interior and the exterior and the roll of external space in each Point. This will explain the alteration of the boundary in housing and extend availabilities of the external space. To achieve this, this research evaluates each Point closely in regards with Le Corbusier's houses. In addition it reveals that the external recognition which is implied in Five Points can be disclosed. This study is also dedicated to explore 'Five Points and the notion and features of external space', 'the formation methods of external space within housing' and 'the relationship of external features within Five Points'.
