255 Park Avenue Nestled on a generous .34-acre corner property in the highly sought-after town of Allendale, this spacious 4-bedroom, 1.5-bath Colonial offers endless potential to create your dream home.

The first floor welcomes you with an inviting entry foyer leading to a bright living room and an eat-in kitchen that opens to a dining area - perfect for everyday living and entertaining. A large four-season sunroom provides additional flexible space and was thoughtfully constructed to support a potential second-story addition, offering exciting opportunities for future expansion. A powder room and direct access to the attached garage complete the main level. Upstairs features a primary bedroom, three additional bedrooms, and a full bath. The full unfinished basement offers excellent potential for a recreation room, home office, or gym. Additional highlights include a standby Generac generator for reliable backup power. Situated on a nearly 15, 000 sq ft lot, this property is ideally located near Allendale’s charming downtown, top-rated schools, and convenient transportation options.
