In this paper we present the findings of an investigation into the ways in which the discourses and practices of school design produce educational spaces which influence the discourses and practices of teaching and learning when the building is occupied. It expands notions of post occupancy evaluation (POE) research by exploring how the objects/motives of an educational vision which informed an initial school design, those of the final build, and those of the people who occupy that building interact in a way which influences experiences of the end users. Crucially we looked at the social interactions that arose within a building as it was used over time. The focus is on the changing relationships between design and practice through time.
