## Description

### Agent Description
Discover classic Colonial elegance combined with comfortable, modern living in this spacious 4-bedroom, 3-bath 1-attached garage and 1- stand free garage home with a full basement set on more than a half-acre of beautifully landscaped grounds. Inside, enjoy bright, well-proportioned rooms filled with natural light and timeless architectural details. The layout flows easily from formal to casual spaces, making everyday living and hosting effortless. Three full baths add convenience and comfort. Outside is a true private retreat: a resort-style backyard with mature plantings, manicured lawns, and multiple areas for dining, relaxing, and play. Whether you envision summer pool parties, quiet morning coffee, or large outdoor gatherings, this yard delivers. The generous lot also offers room for additions, a garden, or recreational amenities. Don't miss this rare opportunity to own a home that blends traditional charm, adaptable living space, and an exceptional outdoor environment.
