This Grade II listed building is a Georgian end-of-terrace house within the St John?s Wood Conservation Area in London, first appears on OS maps in the 1830s, but was intermittently updated and expanded as a reflection of its use through the centuries, with two conservatories added in the 1980?s and 1990?s. As a result of this piecemeal development, by the 21st century, any coherence in circulation or materials had been lost. Robert Dye Associates were asked to re-establish the coherence in circulation, layout and materials as required by a home for a modern single family. As a listed building within a conservation area, significant demolition was a challenge to justify at planning. Westminster Council officers were persuaded to restore the order of the original proportions of the house, supported by coherent modern additions. The 1980?s/1990?s conservatories are replaced by a simple, clean extension which sits as a ?base? to the rear elevation. A brown roof spans the width of the house, reusing demolition material and improving local biodiversity; the entire wall to the garden is glazed with minimal frames. The extension houses a new kitchen and dining room, the heart of the family home. Full-width clerestory glazing to the kitchen ?floats? the modern kitchen addition away from the old house. Flank walls inside and out to the terrace are faced in reclaimed London Stock Brick to provide continuity with the garden walls and house. A new gallery and stair connects the Upper and Lower Ground Floors, detailed with traditional and contemporary materials to allow maximum light into the family rooms behind via an upper level glass box.. Parts of the rear elevation were restored to original proportions. This involved building on an existing flat roof to complete the 3rd storey extension, and replacing a large balcony with a ?Juliet? balcony to match the original on the neighbouring building.
