Hidden behind an understated façade on one of Newton’s most private and prestigious roads, 99 Baldpate Hill Road is an architect-designed, custom-built estate set at one of the city’s highest residential elevations, with sweeping treetop views and unforgettable sunsets. Spanning over 9,100 square feet across four levels, the home features soaring ceilings, walls of glass, custom millwork, and elegant spaces for both everyday living and grand entertaining. Five bedrooms, all with en-suite baths, provide comfort and privacy. The private owner’s level includes an approximately 1,500-square-foot primary suite, executive office, and private terrace. A walkout lower level offers a home theater, recreation space, fitness room, wine cellar, and second kitchen. Set on nearly three-quarters of an acre, the expansive, beautifully landscaped grounds feature a pool, spa, pool house, and multiple outdoor terraces, creating a secluded resort-like retreat just minutes from Boston.
