Ashburn addition remodel FAQs

How long does a home addition take?

Most additions run 3 to 6 months from groundbreaking. Two-story additions and additions requiring structural work on existing foundations land at the longer end.

Do you handle the architectural drawings?

Yes — our in-house design team produces stamped architectural and structural drawings, then we manage the permit submission directly with your county.

Will you match my existing home's exterior?

Yes. We source matching brick, siding, trim profiles, and windows so the addition reads as original construction, not a bolt-on.

Vision Custom built our rear addition and kitchen bump-out at our One Loudoun home in Ashburn. The design-build process meant one team from drawings through final punch list — no finger pointing, no surprises. They matched our existing brick and trim so well that visitors can't tell where the original house ends. Couldn't be happier with the result here in Ashburn.

Added a 600 sq ft family room and primary suite to our Ashburn home in One Loudoun. Vision Custom handled the architect, structural engineer, permits, and build under one roof. The new addition matches the original 1990s brick perfectly — you genuinely cannot tell it wasn't part of the house.
