Abstract
The purpose of this study is to examine and clarify the residents' adjustment behaviors in reference to the process of self-built improvements they made into their dwelling units as in the case of the Medium Rise Buildings (MRBs). Three MRB sites in Metro Manila (two in the City of Manila and one in Quezon City) were investigated. A chronological account of the residents' self-built improvements was investigated together with two parameters (the household structure growth and change and the profession change). In the analysis, we combined the self-built improvements with the two parameters, and as a result, there were eight typical patterns of transformation found in these samples. In addition, we further analyzed these patterns and there were three cases (A,B and C) that described the characteristics and relationships between the self-built improvements and the two parameters. In B case, the self-built improvements were influenced by the two parameters, while A and C cases were not affected by them.
