Every testimonial is from a real homeowner in our service area. We're happy to share references and past project sites on request.
"They added a 600 sq ft primary suite off the back of our home and the seam between old and new is invisible. Every milestone hit, 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."
"Built a full in-law suite above our garage for my mother. They handled the HOA review, permits, and finished a week early. Respectful, clean every day."
Most additions in our service area run between $225 and $400 per square foot, depending on finishes, single vs. two-story, and mechanical work (new HVAC zones, electrical, plumbing runs). We provide a fixed, written price after a free in-home consultation — no surprises.
From signed contract to move-in, a straightforward bump-out typically takes 10–14 weeks. A second-story addition runs 5–7 months. Design, permitting, and HOA review account for roughly half of that timeline — 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 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. Primary suites, second-story bedroom additions, and expanded kitchens deliver the highest ROI.
