About

An empty concrete shell when purchased, this former water tank space has been converted into a one-bedroom, duplex penthouse on top of the Grade II* listed Keeling House, Bethnal Green.

The existing plywood cladding to the East and West elevations was replaced with full-height glazed screens, with sandblasted glass louvres being provided to prevent overlooking. Working at height, one of the key challenges was the 3-storey extension of the existing stair core to provide access to the new flat on the 16th, 17th and 18th floors.

The flat is oriented on an East-West axis so the full height glazed screens flood the space with natural light without overheating. The views of the sunrises and sunsets across the London skyline are exceptional.

The concrete structure has been insulated internally with walls, floors and ceiling all being upgraded thermally. An internal layer of oriented strand board (OSB) provides flexibility and future adaptability in terms of supporting shelving and storage units.

Maximising storage space was a key concern. The bedroom has a raised OSB bed with a child’s bed at one end, a built-in wardrobe underneath and deep drawers within the steps up to the bed. There are cubbyholes along each side of the bed and a trap door at the top of the steps provides valuable storage for larger items.

The built-in bed faces east so you can lie and watch the sunrise whilst an opening roof light overhead allows you to stargaze at night time. Sunsets can be enjoyed from the bath.
