There are 26 two-level houses. The houses have individual main doors which you reach by going down some steps from Willoughby Highwalk at podium level, or by taking steps up from the underground car park. Once inside, you go down stairs to the living area and the kitchen, which are on the lower level.

In the outer houses 1 to 10, and 23 to 26, the staircase between the two floors is a traditional one, and the living room is split level. Most of the floor, including the back half of the living room, is elevated above ground level, but you take a few steps down to the front half of the living room nearest to the lake outside. These split level flats have a storeroom below the living room. (Most owners have converted these storerooms into extra bedrooms, with the Corporation’s permission).

The middle units, 11 to 22, have a spiral staircase, a single level living room and no storeroom.

Every house from 1 to 26 has a bedroom at the front overlooking the lake. The even numbered houses in addition have an extra bedroom at entrance level, at the back. The “evens’” extra bedroom is achieved by stealing some of the “odds’” space next to the entrance corridor.

Nos. 1, 3, 5, 7, 9, 23 and 25 have one split level, living room with a storeroom underneath, and one bedroom (Type 118). Nos. 2, 4, 6, 8, 10, 24 and 26 are the same but have two bedrooms (Type 120). Nos. 11, 13, 15, 17, 19 and 21 have one normal living room and one bedroom (Type 119). Nos. 12,14,16,18, 20 and 22 are the same but have two bedrooms (Type 121).
