“On its own terms this project is almost perfect.” Rowan Moore, Architecture Critic, The Observer
“We didn’t just want a functional pool, but a place designed such that the pupils would really want to go in it. If we were going to do it, we had to do it right. The architect understood our needs and responded with enthusiasm and creativity.” Jinna Male, headteacher, The Observer
“It commands its situation with quiet intensity, much like a gymnast bent on making a complicated procedure look like the easiest thing in the world.” Ellis Woodman, The Architectural Review
“We originally had a very different project, but then we stumbled on the idea of pitched roof, with geometries defined by the roof of the main school building. It seemed to make sense at once.” Joe Morris, Architect
