Journal of Nigerian Institute of Architects (2010) series 1 Golden Jubilee edition, 36-42 SEQUENTIAL HOUSING DEVELOPMENT; A VIABLE STRATEGY FOR LOW INCOME HOUSING DELIVERY IN NIGERIA Jolaoso B.A., Bello N.A. & Jolaoso R.A. Abstract Sequential housing development is an informal programme adopted by the low-income households, whereby housing unit is completed by housing sub unit’s construction method in time phase, through individual efforts to complete housing unit. Housing delivery is a collection of production, regulatory and administrative devices by which housing services are provided to the consumer. This has either been taken up by the government that is unable to cope with it at the macro-level or has been left to the individuals themselves at the micro- level. The consequence as response to the failed government housing policies and programmes has been the emerging development of dwelling units in a shelter-like manner through self-help efforts. It is against this backdrop that the paper appraised sequential housing development for low-income housing delivery, using the development scenario at Akobo Ojurin area of Ibadan as a case study. Data collection is from primary sources, informal interview and field observation, through the use of questionnaire survey conducted by stratified sampling technique within a selected sample frame of 41 houses in the study area. Data collected were analysed using descriptive and inferential statistical methods. The paper makes some recommendations towards achieving success and concludes that sequential housing development is a viable strategy for low-income housing delivery in Nigeria; this needs encouragements through symbiotic relationship among the Government, non-government organisations and relevant professionals. 1.0 INTRODUCTION Housing or shelter has been widely and globally regarded as one of the basic of human needs for existence.

It is a common knowledge that organised human society always makes efforts at placing high premium on the provision of houses for its members through a system of careful policy formulation, planning and implementation in terms of the character, structure, location or neighbourhood of such housing. Agbola (2005) posited that, the house is an institution created for a complex set of purpose beyond provision of shelter. He further posited that, it is a social unit of space where every human being should be housed, irrespective of age, sex and status difference. And that, Housing delivery has either been taken up by the
