"They added a 600 sq ft master suite off the back of our home and the seam between old and new is invisible. Hit every milestone, no change orders."
"We interviewed four contractors for a second-story addition. They were the only ones who showed up with a real sketch and a real timeline. Worth every penny."
"Built a full in-law suite above our garage for my mother. They handled the HOA review, permits, and finished a week early. The crew was respectful and clean every single day."
Most additions in our service area run between $225 and $400 per square foot, depending on finishes, whether the addition is single-story or two-story, and how much new mechanical work is involved (HVAC zones, new electrical panel, plumbing runs). We provide a fixed, written price after a free in-home consultation so there are no surprises.
From signed contract to move-in, a straightforward bump-out typically takes 10–14 weeks. A second-story addition usually runs 5–7 months. Design, permitting, and HOA review (which is heavy in many NoVA communities) account for roughly half of that timeline, so starting early always pays off.
For most additions — no. We seal the work area from the rest of the house, maintain access to your kitchen and bathrooms, and schedule the most disruptive phases (cutting openings, HVAC tie-ins) for minimal impact. For whole-house or second-story projects where the roof comes off, temporary lodging is sometimes recommended.
In Northern Virginia's market, well-designed additions typically recoup 65–85% of their cost at resale and often more in high-demand ZIPs like McLean, Great Falls, and Vienna. A master suite, second-story bedroom addition, or expanded kitchen tends to deliver the highest ROI.
