About this home
This magnificent Georgian Colonial, set on 12+ acres in the heart of Westwood’s estate area, was designed by Johnson, Craven & Gibson and inspired by William Lawrence Bottomley’s Milburne in Richmond, VA. The stunning entry hall with its sweeping staircase is flanked by exquisite formal living and dining rooms, a classic library, and a wonderful breakfast room, all overlooking the south-facing bluestone terrace and grounds beyond. Additionally, there is a spacious kitchen, a butler’s pantry, and 2 wings offering separate living areas for family and guests. Upstairs is a large primary suite with separate baths, 2 ensuite bedrooms, and another bedroom and bath on the 3rd floor, for a total of 6 bedrooms and 6.5 baths. The spectacular grounds include a long private drive bordering the Dedham Country & Polo Club’s 18th fairway. The amazing back lawn is framed by a breathtaking conservatory-greenhouse, a lovely pool and cabana, a peaceful walking path, a tennis court and woods beyond.
