Cork House

This south London property was previously positioned 1m higher than the garden level. To connect the spaces, the homeowners chose Nimtim Architects to develop an extension and renovation scheme. The team created a stepped internal layout, which had the added benefit of forming defined zones for different uses within the revised floorplan. The addition itself is clad internally and externally with cork, chosen because it complements the existing brickwork on the original dwelling and will weather to a silvery-grey over time.

The material achieves good U-values without the need for any additional foam insulation. It also absorbs noise internally, is breathable, free from synthetic resins and harmful chemicals, and is fully recyclable.

Aesthetically, the extension features a simple pitched roof with a large glazed pivot door that frames views of the garden beyond. A slot window on the rear elevation aligns with the rooflight over the side extension to bring in plenty of light and views. Pink window frames provide a pop of colour against the cork, and a pale grey resin finish covers both the flooring and the worktops for a clean and modern look. The house has been shortlisted for the AJ Small Projects award 2019.
