Home Additions in McLean, VA

We build room additions, second-story additions, sunrooms, screened porches, kitchen expansions, and family room additions. We also handle garage additions and outdoor living structures like covered patios. Whether you need one extra bedroom or an entirely new floor, we design and build the addition to look and feel like it was always part of your home.

Yes. We obtain and manage every permit required for your project: building, electrical, plumbing, and zoning compliance. You don’t need to coordinate with Fairfax County at all. We submit the applications, pay the fees, schedule the inspections, and handle any follow-up. This is especially useful for additions, which typically require more permitting than interior remodels.

Additional costs vary significantly based on size, type (single-story vs. second-story), foundation requirements, and finish level. We offer a free initial consultation where we’ll discuss your project and give you a realistic sense of what to expect. Our fixed-rate contract means the number we quote is the number you pay.

That’s the goal, and it’s something we plan for from the first design session. We match or complement your existing architecture, align roof lines, coordinate exterior finishes, and continue your interior design language into the new space. We also handle grading, drainage, and landscaping restoration after construction so the exterior looks finished, not patched together.

Timelines depend on the scope and size of the addition. Additions involve foundation work, structural framing, systems integration, and complete interior finishing, all of which require careful sequencing. We provide a specific timeline before construction begins, and we maintain it through active project management.

We assist with HOA approval as part of our standard process. Many McLean and Fairfax County neighborhoods have active HOAs with specific requirements around exterior changes, materials, and setbacks. We prepare the documentation needed for your HOA submission and can work directly with your HOA if questions come up. We’re also experienced with zoning compliance verification and will flag any setback or lot coverage issues early in the design process.

Yes. Before construction starts, we produce photorealistic 3D renderings showing your finished addition from both the exterior and interior. These aren’t rough concepts. They show actual material colors and patterns, how light moves through the space, and every detail down to fixtures and finishes. What you see in the rendering is what you’ll get in the finished space, which gives you real confidence before any work begins.

Most clients do. We contain the work area, maintain daily cleanup, and protect unaffected areas of your home throughout the project. For additions specifically, most of the early work (foundation, framing, exterior) happens outside the existing footprint, which reduces disruption significantly. We’ll talk through the phasing during your consultation based on the scope of your specific addition.

It’s rare, but it happens. If we discover something like unexpected structural damage after the demo begins, we stop work, explain exactly what was found and why it needs to be addressed, and provide clear pricing before proceeding. That’s one of the only situations where our fixed-rate contract changes, and we handle it with full transparency, not a surprise line item after the fact.

Schedule a free consultation at our McLean showroom at 1389 Chain Bridge Rd, or contact us to arrange an in-home visit. We’ll assess your space, listen to what you’re hoping to build, and give you an honest picture of what’s possible for your lot and budget. There’s no obligation and no hard sell. Most clients leave the first meeting with a much clearer sense of direction than when they arrived.
