* * OFFER DEADLINE August 17th noon * * Welcome to 290 Upper Gulph Road, a spacious Colonial set on over an acre in Upper Merion Township. With four bedrooms, two and a half baths, approximately 2,497 square feet, and a private, established setting, this home offers the space and flexibility buyers are looking for. The main level features a traditional Colonial layout with generously sized living spaces, two fireplaces, a functional kitchen, dining area, and convenient powder room. The layout provides plenty of room for everyday living and entertaining, while large windows bring in natural light throughout the home. Upstairs are four bedrooms, including a comfortable primary bedroom, along with two full baths. The additional bedrooms offer flexibility for guests, a home office, hobbies, or other lifestyle needs. A full basement provides excellent storage and additional potential, while the attached garage and driveway provide plenty of off street parking. The home features natural gas heating with an electric heat pump for backup, along with central air conditioning for year round comfort. Outside, the over one acre lot is a standout feature, offering space to garden, entertain, relax, or simply enjoy the privacy that comes with a larger property. There is plenty of room to create your own outdoor retreat. Location adds another layer of convenience. The property is approximately six minutes from a SEPTA regional rail station, making commuting and access to the greater Philadelphia area more convenient. Major roadways, shopping, dining, employment centers, and the King of Prussia area are also easily accessible. If you have been looking for a Colonial with four bedrooms, a larger lot, garage, basement, and room to make it your own, 290 Upper Gulph Road is one you will want to see.
Gulph Mills, located between King of Prussia and Villanova, is a residential and wooded Radnor Township neighborhood with a creek-cut ravine and winding hillside roads. The neighborhood’s character concentrates around the Gulph Mills Road and South Gulph Road junction, where stone bridges, rail lines, and traffic rhythms frame a distinctly Main Line gateway feel. Large stone colonials and mid-century homes sit back from the road behind mature trees, with pockets of newer builds tucked into cul-de-sacs. Gulph Mills Golf Club and the historic Gulph Mills Station anchor local identity. Valley Forge National Historical Park and the Schuylkill River Trail shape the outdoor cadence, while SEPTA’s Norristown High Speed Line keeps commutes practical.
