Effect of Design Deficiencies on Building Maintenance of Residential Buildings: A Post Occupational Evaluation of Residential Buildings in Enugu Urban, Enugu State, Nigeria

Provision of housing and its quality are two issues, which remained the subject of research and interest to researchers' and designers'. Whenever a designer completes a project, they are not fully aware of the consequences of their design. Only through post occupational survey, the designer usually realizes the shortfall they have made during the design process. Unfortunately, such unforeseen conditions are the part of daily life for the end user of residential buildings in developing cities. The main purpose of this research is to understand and identify the causes of design tribulations and their effects on residential buildings at post occupational stage. This research circumscribes the issues and problems faced by the users of private housing at post occupational stage, which results in because of poor design. These problems affect the users through unplanned maintenance to major repairs leading to danger of collapse. In order to evaluate these effects on buildings, case studies were conducted in housing of metropolitan areas of Enugu State. The finding reveals that the housing is experiencing common building defects for housing such as dampness, facade deterioration and sanitation problem.
