Looking for home addition contractors near you in Annandale? 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 Annandale and the surrounding area.
Why Annandale homeowners pick Vision Custom
Annandale homes are typically 1950s and 60s ramblers, split-levels, and brick colonials on generous lots — which means every addition has to be designed around the actual floor plan, foundation, and roofline of your house, not a generic template. Annandale's mid-century ramblers were built with load-bearing center walls, so opening the kitchen to the living room almost always means a beam and column detail. We engineer that up front so the budget never moves mid-project.
We serve every Annandale neighborhood including Broyhill Crest, Camelot, Sleepy Hollow, Ravensworth, and Hillbrook — across ZIP codes 22003, 22042, 22044.
Permits in Fairfax County

Annandale Reviews
“Our Broyhill Crest rambler had the original 1962 kitchen. Vision Custom removed the center wall, engineered the beam, and gave us one open space from the front window to the back door. They were the only Annandale contractor who explained the structural plan before quoting instead of after.”
Grace P.
Annandale, VA · Kitchen Remodel
“Two full baths gutted in our Sleepy Hollow split-level. New tile, new vanities, and they replaced the old galvanized supply lines while the walls were open — which they flagged honestly instead of covering it up. Fairfax County inspections passed first time.”
Danny T.
Annandale, VA · Bathroom Remodel
“Finished our Annandale basement into an in-law suite for my mother — bedroom, full bath, and a small kitchenette. Permits, egress window, everything handled. The crew was respectful of my mom being home during the day.”
