ABSTRACT
Introducing flexibility and adaptability in the design of an Expo centre, Abuja is the quintessence of the work. Expo centre, Abuja is a centre where different activities are organised on daily, weekly, bi-weekly, monthly and annual basis. The centre is multi- functional is use. Hence the study aims at examing the concept of flexibility adaptability in architectural design. Various expo centre in Nigeria and abroad were also evaluated in terms of their spatial and functional requirements which were considered as determinants to designing the existing expo centre; as well as showing their various uses in reflecting flexibility and adaptability in application. Quantitative data such an interview document (secondary data) and participant observations were practically exhibited in the methodology. The findings revealed that certain facts that the centre would be use all year round were not known by operators as some structure remained dormant and not in use forgetting that the structure is multidimensional and functional in uses. The study also came up with the design of International Expo Centre which bear a trademark of international outlook as depicted by the study.
