The renovation and extension of this 1930s duplex by Virginia Kerridge Architect saw a double height box added behind the building extending the lower floor apartment. The contemporay space provides a kitchen dining area above and an intimate sitting area that opens to a pool. "The concept behind the scheme was to leave the existing building in close to original condition with the addition being treated as a “box” for living in..." Please Santa. I've been a good girl this year. Could you leave an extension just like this behind my house this Christmas morning?
