Evaluating housing projects is an essential task to determine the effectiveness of these projects and to provide a useful feedback to the projects’ initiators - be it the public or the private sector. The evaluation could be on a number of different bases. Reports the results of research work aiming to compare the quality and effectiveness of three housing projects initiated by the Yemeni government in the capital - Sana’a. The basis chosen for evaluating the public low-income housing schemes is the housing quality measurement technique. This technique is used for measuring quality under widely different housing standards. It is a way of assessing the environmental quality and hence evaluating the success or failure of a particular housing project. Satisfaction of residents has also been evaluated and reported in an earlier paper (Al-Abed and Mustapha, 1996).
