ABSTRACT
Of all the influences on mankind, the environment is one of the most bearing on him. The environment, as defined by psychologists ranges from one's immediate physical surroundings, e.g. buildings, walls, colour of walls, to relationships with other people. How one perceives and reponds to these eventually moulds his character. Hence the objective of this thesis is to invetigate into the effect of the prison environment on convicted offenders with particular reference to Nigeria. In view of these, an attempt was made to discover a more humane architectural approach to prison design that would meet the requirements of the society i.e reintegration and reformation of the inmate so as to protect society. An extensive analysis of architecture features, influences and effects of prison on inmates psychologically, with the hope of designing a prison that aids reformation.
