 The Pre-school centre is a classic example of the 'Melbourne Regional style' of the 1950s, with its boldness in structure, geometry and colour.The Burwood Pre-School is a single-storey building, comprising a large central playroom with a distinctive zig-zag roof.Framed up with diagonal steel members in a scissor-like configuration, the zigzag roof essentially comprises three contiguous butterfly roofs, forming three small gables with an upward-sloping skillion at each end.
