Will Gamble Architects frames Ribbon House extension with weathered steel

Weathered steel shaped like a "pressed ribbon" frames the rear extension of this Victorian townhouse in London, renovated by local studio Will Gamble Architects.

Named Ribbon House, the original home was expanded into a five-bedroom dwelling through the addition of both loft and rear extensions, and the overhaul of its existing interiors.

The client's wish for a palette of "earthy tones" informed Will Gamble Architects' use of Corten steel to frame the extension.

Inside, this was complemented by terracotta tiles, brass fittings and green-toned carpentry alongside reinstated Victorian features.

"The design is influenced by the use of natural materials, and the client's desire to introduce earthy tones," founder Will Gamble told Dezeen.

"This approach started with the natural patina of the Corten-steel opening, the angular folds of which recall a pressed ribbon, simultaneously delicate and strong," he added.

"Subsequently, it influenced the material palette internally – terracotta tiles, oak flooring, microcement worktops and a medley of greens were used throughout the house."

Within the rear extension, a skylit living, dining and kitchen space is flanked by two walls lined with built-in storage, including full-height cupboards finished in a pale shade of green and more open display spaces and shelving in oak.

A lounge area sits beneath a skylight lined by timber slats and overlooks the garden through full-height sliding glass doors that open onto a paved patio.

At the back of the space, Ribbon House's kitchen is organised around a microcement island with curved corners.

Above the worktop, a section of terracotta tiles introduces the earthly palette into this area, carried through into a terracotta-toned pantry tucked into one corner.

"The joinery plays an important role in the spatial organisation of the space whilst providing ample storage," Gamble explained.

"Floor to ceiling cabinetry, with vertical fins, is broken up by oak inserts that help demarcate the key zones within the open plan space – these zones include the informal sitting area, dining space, and kitchen," he added.

The oak and green timber finishes have also been introduced into the existing home, including in a pale green "library wall" in the living room that conceals a small bar.

Alongside these additions, elements such as ceiling roses, cornicing and skirting have been reproduced to match their historic appearance.
