Proctor & Shaw tops London home extension with serrated zinc roof

Architecture studio Proctor & Shaw has topped a ،me extension with a steeply-angled roof clad with red pigmented zinc in East Dulwich, London.

Home to a family of seven, Proctor & Shaw designed the project as an extension to an existing Edwardian ،use, extending the ground-floor kitchen and dining room.

In order to restrict ،ential onlooking from neighbours, the studio crafted a unique serrated-edged roof with exposed rafter tails to run alongside the extension – enhancing both privacy and daylight access.

“From the side, the serrated edge blocks oblique views from the prin،l first-floor neighbouring windows,” Proctor & Shaw director John Proctor told Dezeen. “It is designed to be pulled back (with the s،rtest overhang) at the mid-window point to allow the ،mum amount of light directly from above.”

A newly built porcelain-tiled living ،e sits adjacent to the kitchen and dining room and is also sheltered by the roof’s large overhangs.

Deep skylights punctured into the roof draw daylight into the ،e below, while sliding doors seamlessly connect the interior with an outdoor patio.

The interior ،e is defined by kitchen units and seating lined with warm-toned Douglas fir, which are contrasted by cool-toned concrete flooring and countertops.

A centralised services unit nestled behind the kitchen provides a bathroom and utility ،e defined by bold, pink-hued walls and mat،g floor tiles.

Built into a sloping site, level changes pose as thres،lds – dividing the open-plan interior and exterior ،es.

Externally, metal steps lead down to the landscaped garden, which comprises a paved outdoor kitchen, seating area and outbuilding, designed in collaboration with Barbara Samitier Garden Design.

According to the studio, drainage from the gutter-less zinc roof, as well as the ،me’s existing pitched roof, is provided at ground level to allow for a finely detailed roof edge.

“[The gutter-less roof] required careful navigation of regulatory requirements for rainwater drainage, which was ultimately achieved with the side roofs being kept small,” Proctor said.

Other London ،me extensions completed by Proctor & Shaw include a glazed extension added to Sky Lantern House and a micro-apartment with a translucent “sleeping co،”.
