An addition is the one project where zoning can stop you before design starts. We are a licensed contractor in Virginia (Class A #2705183185) — we pull the permits through Fairfax County Land Development Services, coordinate the licensed trades, and hand you a written line-item scope before demolition starts.
An addition starts with zoning, not construction: setbacks, lot coverage and height limits get reviewed before a building permit is issued, and in some neighborhoods there is a stormwater or historic review on top. Then come the footing and foundation inspections, which have to pass before backfill. This is the longest-lead permit of any project we do, and it is why we start the paperwork while the design is still being drawn.
Your McLean permit goes through Fairfax County Land Development Services. We pull it under our license and we hold the inspection schedule — you do not chase inspectors and you do not sign the application.
What we find in McLean homesMcLean is large-lot housing — 1950s–1970s ramblers and colonials alongside substantial newer construction and rebuilds. On the original houses, additions are common and usually worth doing properly: matching roofline, siding and HVAC capacity so the addition does not read as an add-on. Many neighborhoods also carry HOA architectural review.

Most McLean projects land in the $180 – $340 / sq ft range. That is a planning range for Fairfax County, not a quote — your written price comes after a free on-site walkthrough.
Yes. The walkthrough and the written scope are free and yours to keep whether or not you hire us. There is no design fee and no consultation invoice.
The build is rarely the long part — permitting and zoning review are. Expect the approval phase to run in parallel with final design, and expect us to give you a schedule that names the permit milestone rather than hiding it. We will tell you at the walkthrough if your lot has a setback or coverage problem, because that changes the whole conversation.
