Home Extension Contractors Wilmington NC
Rear, side, and second-story extensions that blend seamlessly with your existing home. 500+ projects completed with 20+ years of coastal construction expertise.
Need more space but love your neighborhood? A home extension lets you expand without moving. At Swanson Construction, we design and build extensions that integrate seamlessly with your existing architecture — matching rooflines, exterior finishes, and interior flow. Our coastal expertise means proper wind-bracing, hurricane clip systems, sandy soil foundation engineering, and moisture barriers built in from the start.
