Looking for home addition contractors near you in Clifton? Vision Custom Build & Remodel is a licensed Class A Town of Clifton / Fairfax County contractor that designs and builds bump-outs, second-story additions, primary suites, sunrooms, and in-law additions across Clifton and the surrounding area.
Why Clifton homeowners pick Vision Custom
Clifton homes are typically victorian historic-district homes and large-acreage custom estates — which means every addition has to be designed around the actual floor plan, foundation, and roofline of your house, not a generic template. The Town of Clifton is a designated historic district, and many surrounding properties sit on wells and septic on multi-acre lots. Additions here need health-department review for septic capacity — we handle that filing with the county.
We serve every Clifton neighborhood including Historic Clifton, Balmoral Greens, Clifton Point, and Kincheloe — across ZIP codes 20124.

Clifton Reviews
“Three-acre lot on septic, and our addition needed health department sign-off. They managed that filing plus the county permits and kept us informed weekly. Finished the sunroom addition ahead of schedule.”
