Inside, most maisonettes display open-tread cast terrazzo staircases projecting from the party walls as a cantilever. This, and the fact that the bedrooms are suspended, structurally speaking, without supports over the living rooms gives very compact planning with a surprisingly spacious feel to small flats, in spite of the fact that they were built under the severe Government building restrictions of the post-Second World War period. The engineer was Felix Samuely. Some maisonettes retain their hour-glass shaped hot-water radiators, visible in windows.
