Looking for home addition contractors near you in Fairfax Station? Vision Custom Build & Remodel is a licensed Class A Fairfax County contractor that designs and builds bump-outs, second-story additions, primary suites, sunrooms, and in-law additions across Fairfax Station and the surrounding area.
Why Fairfax Station homeowners pick Vision Custom
Fairfax Station homes are typically 1980s and 90s custom colonials on half-acre-plus wooded lots — which means every addition has to be designed around the actual floor plan, foundation, and roofline of your house, not a generic template. Fairfax Station lots are big and heavily treed, so additions and sunrooms are very achievable — but Resource Protection Area setbacks near Pohick Creek matter. We check RPA mapping before a single drawing is made.
We serve every Fairfax Station neighborhood including Crosspointe, South Run, Hampton Forest, and Barrington — across ZIP codes 22039.
Permits in Fairfax County
Every home addition in Fairfax Station requires sealed architectural and structural drawings plus permits through the Fairfax County Land Development Services.

Fairfax Station Reviews
“Crosspointe home, and part of our lot is in a Resource Protection Area. Vision Custom checked the RPA mapping before designing anything, which two other contractors never even mentioned. Addition approved and built without a single hold-up.”
