The existing rear extension and part of the rear wall of the existing building were demolished to add a new rear extension, loft extension, and basement. We created five self-contained units of residential accommodation. The proposed new additional flats to involve extending the existing three-storey dwelling. The basement and ground floors are designed as two three bedroom family-size duplex flats with access to a private garden. The first, second and third floors are arranged in to three two bedroom flats, two of them are duplex with roof terrace. Four lightwells, two in the front and two in the rear, offer high levels of light to the basement. Extension is cladded in high-quality Siberian larch softwood with a vertical pattern to accentuate a visual slimness to the extension when viewed from afar, which it is a natural and sustainable material that has strong traditional roots to complement the historic building. It will weather over time to a grey-brown patina, which is consistent with the colour palette of the area. We have utilised this material to complement on the weathered brick of the existing dwelling and create a design that is contextual yet striking.
