By taking advantage of the different site levels, Collins was able to reduce his excavation to a minimum. If the road is higher than the garden, then the rear of the house lowers itself to garden level. If the garden is higher, the rear rooms are reached by a few steps, or the whole front of the house is raised, with a flight of steps in the front garden and the cellar door almost level with the front garden. Each house rises or falls according to the site and this produces the varied roof lines.

A typical Birchwood Avenue house.
