Access to flats is via lifts and circular stairwells at regular intervals along the block. Each lift/ stair unit serves a group of six flats clustered round it on each floor. On either side of the lift/staircase are two “large” studio flats back to back. They each take up one half of the depth of the building. In between those four large studios is the lift/stair. But that only takes up about a third of the building width, leaving space on either end for a “small” studio. (Small because they do not back onto each other, like the large ones, but onto the lift/stair unit, which steals depth from them). On the 1st floor there is just a single row of studios. Small or large, they are essentially laid out the same. They have front windows only . Each has a kitchen and a bathroom at the back. There are 66 “large” studios (Type F2a) and 33 “small” studios (Type F1a).
On the top floors are 12 two-room penthouse maisonettes, which have a living room and kitchen on one floor and a bedroom and bathroom above, connected by a spiral staircase, and a roof terrace on top (Type P2a).
