First time on the market! Curb appeal and great location! Welcome to this spacious 5-bedroom, 2 full-bath expanded colonial (over 2,500 sq ft) in the heart of Plainsboro! This custom-built home features hardwood floors, ceiling fans, built-ins, and a bright, inviting first-floor sunroom with windows all around. The first floor also provides a functional and well-designed layout, including 3 bedrooms, 2 full baths, a kitchen, side entry/mudroom with pantry, laundry room, and formal living and dining rooms, both with hardwood floors. Upstairs, two additional bedrooms and a large landing also feature hardwood floors. An unfinished basement provides ample storage space and includes the water heater & furnace. A brand-new A/C system was installed in August 2025. In 2011, a significant addition (over 900 sq ft) expanded the home, creating a sunroom (200 sq ft) and two large bedrooms at the back of the house—one with a full en suite bathroom and walk-in closets. Set on a beautifully landscaped, level lot with mature trees, shrubs, and flowers, the property offers a front porch, side patio and entrance, and a back door off the sunroom. A long driveway leads to the detached, expanded 2-car garage, and the deep backyard includes a storage shed. Ideally located, just steps from parks and Plainsboro Center (library, Township Center, shops, restaurants, and health care), with the bus line two blocks away and NJ Transit’s Princeton Junction train station less than 5 miles from the home. Students attend the acclaimed West Windsor-Plainsboro public schools, with the elementary school across the street and middle and high schools just a few blocks away. A wonderful opportunity to make this home your own!
