A Brick and Glass Extension Telescopes Out Across the Roof of a London Home

Houses We Love: Every day we feature a remarkable space submitted by our community of architects, designers, builders, and homeowners.

Project Details:

Location: London, England

Architect: Andre Kong Studio

Photographer: Luke O’Donovan

From the Architect: "Andre Kong Studio has extended a Victorian terraced house in southeast London by extruding a series of stepped brick volumes hosting a new bedroom, study, and bathroom."

"The brief emerged out of two significant post-lockdown changes for the family: the arrival of another child and a shift to permanently working from home. Suddenly the family were outgrowing their house and needed more space and a refuge from the rest of the busy youth-filled household.

"Echoing the original plan of the house, the massing follows its L-shape, breaking down an otherwise imposing mass. This is achieved with volumes that step down like a telescope, pulling out of each other, articulating clerestories for light filled rooms.

"The grey brick cheeks of the outrigger, which blend with the roof color, follow the same stepping logic, creating a tapered and textured effect. The sizes of the stepping brickwork define the form. The dimensions of the materials also inform the scale and proportion of the lighter brick portals from which each smaller volume is drawn out of.

"Instead of using full bricks, which would have been heavy and would have required unsustainable and costly structural steel upgrades to the existing house, Andre Kong Studio opted to use brick slips on a lighter insulated timber structure to create the same effect whilst also achieving a better thermal performance for the same thickness of wall. The existing roof tiles were retained and reused to minimize waste.

"The light-filled interiors feature natural materials such as natural wood and stone, exposed timber rafters and the original brick walls, celebrating the stepping brickwork of the chimney stacks to reinforce a relationship between the inside and out, between old and new."
