Archmongers has turned a section of walled garden in a 1980s house in south London into a living space with sawtooth roof, earning it the dinosaur-inspired name Stego.
London-based architectural studio Archmongers, headed by architects Margaret Bursa and Johan Hybschmann, refurbished the house in Kennington to create a more practical layout.

The end-of-terrace property had two bedrooms upstairs and a cramped ground floor containing all of the living areas. It also featured a freestanding garage with its own access.
Archmongers opened up the ground floor by adding a single-storey extension that occupies part of the house's underused walled courtyard garden.

The extension connects the existing house with the converted garage and is topped with a saw-tooth roof that is visible above the outer wall. The vertical protrusions evoke the plates on the back of a stegosaurus, which gave the project the name Stego. The house's brick facades and boundary wall are treated with a dark stain to distinguish it from the rest of the terrace and ensure the old and new sections have a unified appearance.

"The planning authorities were very supportive and were happy to see something that was convincing and gave this type of property some real character," Bursa told Dezeen.
Stego also involved updating the building's exterior by replacing an existing wooden porch with a new addition that breaks up the facade and provided much-needed storage space.
