This study examined the quality and the factors which contributed positively and negatively to the quality of some selected students residential facilities in Nigeria. A user-perspective approach was adopted. The quality of the selected facilities was examined at three levels of environmental interaction and from architectural and social dimensions. Twenty purpose-built halls of residence were selected from four Universities in Nigeria and two thousand students were selected from these halls using the stratified method of sampling. The results revealed that students' halls of residence were perceived to be below average in overall quality and the attributes which contributed the most to this low level of quality were the socio-physical characteristics. Out of the three levels of interaction examined, the bedroom was the only level that was assessed as poor in quality. The results further showed that the social unit size defined at the level of the bedroom as well as the bedroom for studying were the factors, which contributed most negatively to overall quality, signifying their importance. Finally, the implications of the findings for planning and designing future residential facilities were highlighted. (Contains 10 figures.)
