    Home Additions for Plaistow Homeowners

    Plaistow is our home base — Ryan & Greene Construction has been headquartered at 23 Plaistow Road since the early days, and we've remodeled more homes within ten miles of Pollard School than anywhere else on the map. From the colonials off Sweet Hill Road to the newer subdivisions near Westville, we know the housing stock, the building department, and the contractors and suppliers who serve this corner of Rockingham County.

    Plaistow's housing mix runs from 1700s antiques near the town center to 1980s splits and capes off Old County Road, plus newer construction in the Westville area. Most kitchens and baths we touch here are tucked into homes between 1,500 and 2,400 square feet with the original layouts still in place. That context shapes how we approach a home addition in Plaistow — the layouts we recommend, the materials that hold up, and the timeline we can hit. Most of our Plaistow additions clients come to us by word of mouth from a neighbor we've already worked for.

    Neighborhoods we work in: Westville, Sweet Hill, North Avenue, Old County Road, Main Street corridor.
