Abstract
In Brazil, since informal and self-managed construction projects are compromising the individual and collective scale of multi-story apartment construction, this study aims to clarify the nation's support and infill (SI) system division, as well as its implementation requirements, in terms of housing demands, national laws, and the development level of the housing industry. To accomplish this, 16 remodeled apartments were examined and interviews were conducted with a number of Sao Paulo real estate developers and managers. The results showed the following: 1) self-managed adaptation is not only related to infill, but also to support level decisions; 2) local building legislation, condominium bylaws, and the available building systems are unresponsive to actual user demands and the decision-making processes.
