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.

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.
