“Just add a family room” is the most expensive sentence in Lower Bucks after “while you’re here, open the kitchen.” Additions in Fairless Hills, Levittown, Morrisville, and Newtown share a climate and a labor market. They do not share lot lines or inspectors.


AI Home Renovations prices additions from Fairless Hills, PA, within about 25 miles.


2026 planning numbers


  • Bump-out (4–8 feet, existing roof logic): $40,000–$75,000
  • Ground-floor room, new foundation: often $150–$350 per finished square foot
  • Second story over an existing footprint: structural engineering plus living in a noisier house for months

    • Kitchen or bath inside the addition is not “included in the box.” It is a remodel stacked on a building addition.


    What townships care about


    Falls Township setbacks on Fairless Hills lots. Bristol Township vs. Middletown on Levittown sections. Morrisville Borough lots that look deep until you measure rear yard. We confirm the parcel before anyone falls in love with a 16-foot rear bump-out that violates coverage.

    Frequently asked questions

    How much does a home addition cost near Fairless Hills?
    A small bump-out often starts around $40,000–$75,000. A full room addition commonly runs $150–$350+ per square foot depending on foundation, kitchen or bath ties, and finish. Second-story additions are their own structural bid.
    Is a Fairless Hills addition cheaper than Newtown or Yardley?
    The dirt work and finishes dominate, not the town name. Setbacks and lot coverage in Lower Makefield or Newtown can add design time. Mileage from our Fairless Hills shop is not the driver inside 25 miles.
