| Abstract |
The purpose of this study is to trace the change in the lower public space of high-rise office buildings since 1960's. To analyse the office buildings due to density properly, this study goes through analysis related to the lower public design factors. In this study , the lower public space means that it contains floors directly connected ground level. The results of this study are as follows; Firstly, the development density of the high-rise office building is determined by the zoning code(building coverage ratio/floor area ratio/height of building)and the physical conditon of site(size, form, slope, road). As the building coverage area is related deep with the exterior composition regulation like landscape and public open space regulation, the floor area ratio and height codes become more powerful determinant than building coverage ratio. Secondly, the development density of high-rise office buildings rose up in process of time and the demeand for the lower public space was increasing as the space of gathering potential clients. Thirdly, the size of the lower public space shows steady growth and composition of tenant get the high level of diversity. But the non-profit space is decreasing or changing into the similar-but profitable tenant in pursuit of profitability. Fourthly, the visual openness mount up with the increase of vertical void space and lobby directly connected with exterior. and physical accessibility also goes up, increasing the number and length of entrance. |
