Abstract
The Century Housing System (CHS) is one of the early systems applied to newly-built houses for their long-lives. It is 15 years since the first CHS house was built. Some interviews were held about 6 CHS houses and questionnaires sheets for dwellers were distributed at two of them. This paper is made mainly of the questionnaire statistics and the interviews are used to refer to some related problems. The openings for inspection are not used very frequently and estimated by more frequent users like building managers. The long-life of the structure and the effectiveness of the plan flexibility and the building component part changeability are not sufficiently proofed because of the short term after the completions. The problems on the long term maintenance of building components and information for the dwellers on the CHS are brought up through this research. Especially for multi-family dwellings, the long term maintenance of the common building components and space should be considered to realize their total long-lives.
