A courtyard extension of a canalside house in Islington, London

The aim of the project was to convert a small disused courtyard belonging to the property into a two-storey extension of the main house.

Situated in the Islington conservation area it was originally the lock keeper's house with the small unused courtyard bounded by an industrial unit on one side, a listed boundary wall to adjacent properties and the main house.

The project was particularly difficult due to the listed wall coupled with the constraints to the main elevation which could not have windows overlooking neighbouring properties.

The design involved underpinning all the adjacent walls and digging down 3m to lay foundations to keep the roof level below that acceptable to the conservation criteria during which the discovery and survey of Victorian drains served to prolong the construction programme.

The result is an interesting pendentive wall clad in matching stone with 600mm high strip windows that at ground level shedding light and ventilation into the lower bedroom. A new front door was installed accessing both the extension and house, and a sun room with a moving glass roof.
