About this home

Prominently sited, this six-plus bedroom Colonial Revival has been stunningly updated with flair and panache while maintaining much of its 1896 design. Rich in detail with modern simplicity, this home has it all! Designed for gracious living, the grand entry foyer leads to a sun-filled main level with spacious formal rooms, including a fire-placed dining room with built-in seating, a living room with a gas fireplace and French doors to a covered terrace, and a family room with palladian windows and French doors to the outdoors. The original butler’s pantry connects to the kitchen with premium appliances, a dining area, and French doors to the deck and private yard. A mudroom, home office, and half bath complete this floor. The second floor offers six-plus bedrooms, two bathrooms, and laundry. With oversized windows, gleaming wood floors, high ceilings, central AC, and updated systems, this home is ideally located near the Brookline Reservoir, schools, and the medical area.
