Northern Ireland studio McGarry-Moon Architects has renovated a historic house in west London, and added a contemporary timber and concrete extension connected by a glass-lined corridor (+ slideshow).
Warren Cottage is a Victorian property situated within the Coombe Wood conservation area in Kingston upon Thames.
The house is heritage-listed due to its former role as a gatehouse to Richmond Park, the largest of London's Royal Parks.
McGarry-Moon Architects ? which previously converted an old stone barn in Ireland into a contemporary home ? was tasked with refurbishing and extending the cottage to create a more spacious home.
A lack of maintenance had left the cottage in a dilapidated state, so a restoration process was undertaken.
This involved improving the building's thermal performance by adding modern insulation and slimline double-glazed windows.
Rather than seeking to mimic the traditional look of the cottage with the extension, the architects chose to adopt a more contemporary aesthetic.

The new additions comprise a two-storey extension with glazed walls, connected to a more compact lounge contained in a board-marked concrete volume.
A separate concrete structure houses a garden room looking out onto a small pool.
"The form of the extension seeks to contrast the ornate and traditional nature of the cottage whilst acknowledging that it is from a different time," added Currie.
"This is also echoed through the contrasting use of materials"
