Housing Construction in Chinese cities greeted a new upsurge since 1949,the floor area of housing construction approximately amounted o half of the total floor area of the new construction, China so took the first position in housing construction in the world. However, generally speaking, the standard of housing construction in China is still low, it seems that the technology in housing construction in isn't well prepared while it is in large scale, especially in the living and use performances which can't meet the daily growing requirements of material and spiritual lives. In view of this situation, a regulation was promulgated, that is Commodity Building Performance Confirmation.One of the important content in the Regulation is the principle of plane and space layout. Among the building performances, the plane figure for housing is the base and frame in showing its essence and also the base of architectural design, the probe and research to housing types are the first for housing design. The problems on construction function usually are reflected concentrately in plane design, in which the main content of the space compose is done too.This paper proceeds from the principle of plane and space, researching if the housing function and quality demanded in the Regulation and the residenters' living standard are well coordinated, and if they are well done in suiting their living style and things like that.The paper starts with the basis theory of architecture, combining the other relative theories and available results of research, paying a visit to the thirteen selling built commodity housing estate, getting the opinions and data faded back from investors and households, it then discusses the problems existing in the available housing and the developing trend in housing design. After comparing these problems with the rules in the principle of plane and space layout required in the habitability in the Regulation, the paper discussed if the Regulation adapts to the real situation in Xi'an city.The purpose of writing the paper is to hope to propose the original and potential ideas in design by comprehensive research in forms and functions of different housing types, the more proofs to the foundation and the result mentioned in the Regulation, and the discussion to the part of the provisions of the Regulation.. |
