Looking for home addition contractors near you in Merrifield? 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 Merrifield and the surrounding area.
Why Merrifield homeowners pick Vision Custom
Merrifield homes are typically mosaic district townhomes, 1950s ramblers, and infill new construction — which means every addition has to be designed around the actual floor plan, foundation, and roofline of your house, not a generic template. Merrifield mixes brand-new Mosaic District townhomes with 1950s ramblers a block away. The older homes usually need panel upgrades and cast-iron drain replacement alongside the remodel — we price that honestly instead of discovering it later.
We serve every Merrifield neighborhood including Mosaic District, Dunn Loring, Providence, Luther Jackson, and Woodburn — across ZIP codes 22031, 22042, 22116.

Merrifield Reviews
“Mosaic District townhome kitchen. Tight access, no driveway, and they still managed deliveries perfectly. Cabinetry quality is well above what the builder installed originally.”
Chris A.
Merrifield, VA · Kitchen Remodel
“1950s rambler off Gallows Road. They found cast-iron drain lines behind the wall and gave me a written change order with photos before touching anything. That kind of honesty is rare.”
Laura B.
Merrifield, VA · Bathroom Remodel
“Basement finished with a guest suite and wet bar. Permits through Fairfax County went smoothly and the inspector complimented the framing. Would use them again without hesitation.”
