    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.

    What We Do

    Rear Extensions

    Expand toward the backyard for larger kitchens, family rooms, or open-concept living.

    Second-Story Additions

    Add bedrooms, bathrooms, or home offices above your existing footprint.

    Sunroom & All-Season Rooms

    Four-season rooms with impact-rated windows, HVAC extension, and matching rooflines.

    In-Law Suites & ADUs

    Self-contained living spaces with kitchenettes and accessible bathrooms.

    Hurricane-Rated Construction

    Wind-bracing, continuous load paths, and coastal-grade engineering for storm resistance.
