This elegant 1930's era home received a 3,500 sf addition and renovation that is truly seamless, inside and out. The addition includes a second kitchen, an exercise room with changing room and bathroom, and a loft-style home office that overlooks the new landscape from a private balcony. Other touches include seamless integration of existing materials, from the stucco and specialty doors and windows to the reclaimed slate roof that was painstakingly matched to the existing. The overall result is an expansion that is indistinguishable from its original, as though it was always there.
