Originally built in 1937, this renovated 4 bed, 4.5 bath East Coast Traditional residence in Windsor Square pairs beautifully preserved character with an exceptionally livable floor plan, offering approximately 3,410 square feet on a fully fenced, private corner lot within the coveted Third Street Elementary School boundary and just moments from Larchmont Village. Designed by architect W. George Lutzi, the two-story home is rich in original detail, with ornate ironwork and hardware, hardwood and brick floors, gracious millwork, extensive built-ins, and oversized windows framing the surrounding greenery. Mature hedging and established landscaping envelop the property, creating a remarkable sense of privacy, while generous interiors open naturally to a pergola-covered brick patio and lush backyard designed for entertaining, with room for a pool. A classic center-hall entry and grand staircase introduce the main level. The formal living room is anchored by a brick fireplace flanked by custom built-ins, while an adjoining sitting room with brick flooring and built-in bookcases opens directly to the rear patio. The chef's kitchen features Carrara marble countertops, a six-burner Viking range, Sub-Zero refrigerator, farmhouse sink, abundant cabinetry, and shuttered windows, flowing into a bright den with additional built-in storage. The adjacent formal dining room features beautiful millwork and bay windows overlooking the garden, while a floral-wallpapered powder room adds a playful finishing touch. Also on the main level, a flexible guest suite, office, or playroom includes a Murphy bed, built-in shelving, a large closet, full bathroom, and direct patio access. A separate laundry room provides additional storage and its own exterior entrance. Upstairs, the expansive primary suite occupies its own side of the home and includes a separate sitting room or office, along with a large walk-in closet featuring custom wardrobes and a window seat. The primary bathroom is finished with dual vanities, Zellige tile, and a freestanding clawfoot tub set within an oversized shower. Two additional bedrooms with generous closets and charming built-ins share a Jack-and-Jill bathroom, while a separate hall bathroom makes a statement with emerald-green Zellige tile. Outside, mature hedging and established gardens create a private setting on the corner lot. A wide brick patio beneath a classic white pergola offers ample space for lounging and al fresco dining, complemented by a built-in outdoor kitchen with Lynx grill, refrigerator, and prep space. A grassy yard, mature trees, climbing greenery, and layered plantings complete the garden, while the detached garage offers convenient access from the side street and potential for future ADU conversion.
