Property Description

Set on a beautifully landscaped, nearly half-acre property on a quiet cul-de-sac, this gracious four-bedroom, 2.5-bath home offers timeless architectural character, generous living spaces and exceptional modern comfort. Thoughtfully updated and meticulously maintained, extensive improvements beginning in 2020 have enhanced the home while preserving classic details—including wainscoting, panel molding and hardwood floors. Nearly 3,000 square feet of above-grade living space features an inviting foyer, elegant living room with wood-burning fireplace and built-ins, formal dining room, comfortable den and sun-filled eat-in kitchen. Sliding doors from the den open to a Trex deck, creating wonderful indoor-outdoor flow. A powder room, custom pantry and laundry room complete the main level. Upstairs, the exceptional 750-square-foot primary suite provides a serene retreat with walk-in closet, linen closet and spacious en-suite bath featuring a spa tub, separate shower, dormered ceiling and dual vanities. Three additional generously sized bedrooms and a full bath complete the second floor. The finished lower level offers an additional 450 square feet of flexible space, ideal for a media room, gym, office or playroom, plus 650 square feet of unfinished storage and utility space. Additional features include Pella windows, recessed lighting, custom window treatments, California Closets, an in-ground sprinkler system and a two-car garage renovated in 2026. Outdoors, the expansive, level backyard is a true highlight, with mature trees, perennial gardens, sweeping lawn and a large in-ground pool creating a vacation-at-home setting. Recent pool improvements include a new sand filter, super pump, heater and underwater light. The deck’s electric retractable awning provides comfortable outdoor entertaining space. Ideally located within walking distance to West Windsor-Plainsboro South High School and Princeton Junction Train Station with express service to NY Penn Station, and just an eight minute drive to downtown Princeton’s historic charm, cultural institutions, fine dining, elegant shopping and remarkably walkable downtown.
