Revitalising an empty concrete shell, this former water tank space has been converted into a one-bedroom flat on the 16th, 17th and 18th floors of Keeling House. Due to the Grade II* listing, insulation has been provided internally with the walls, floors and ceiling all thermally upgraded. The existing plywood cladding to the east and west elevations were replaced with full-height glazed screens, with sandblasted glass louvres preventing overlooking whilst flooding the space with natural light. Maximising storage space was a key concern, with bespoke furniture including a raised bed with a child’s bed at one end, a built-in wardrobe underneath and deep drawers within the steps.
