This drawing is best viewed in tandem with the plan of Hallfield School (PB868/3 (3), also included in the Study Room resource box. Through looking at these drawings together, we can get some idea of how Lasdun generated his ideas for the design of Hallfield school in Paddington. Classrooms were imagined as leaves branching off a stem which functioned as the corridor linking the teaching spaces together.
Exactly how well Lasdun managed to transform this idea into reality, and more importantly perhaps, how significant the concept was for those children who used the building is debatable. However, if you underlay this drawing behind the ground floor plan it is possible to see how well the idea of biomorphic forms fits the plan of the building as it was eventually built.
