One Team, One Process

From initial architectural drafting to structural framing and final walkthrough, every decision flows through a single coordinated team. We eliminate miscommunication between separate architects and builders, keeping your home addition on schedule and within budget.

VA Class A Licensed Contractor

We hold a Virginia Class A General Contractor License (#2705177340). This ensures your home addition meets all structural engineering standards, load-bearing requirements, and local zoning/building codes in Alexandria and Fairfax County.

In-House Crew on Every Job

Most contractors subcontract critical framing or foundation work and disappear. We self-perform the core phases of construction with our trained in-house crew, ensuring structural integrity, job site safety, and consistent quality from excavation to roof tie-in.

Clear Pricing, No Surprises

Before groundbreaking begins, you receive a detailed itemized estimate and a structured construction schedule. You get fixed-price transparency with clear milestone timelines so you know exactly what your expansion costs at every phase.

Built for Alexandria Homes

Based right here in Alexandria, VA, we have deep, practical experience navigating Northern Virginia property setbacks, lot coverage restrictions, and local architectural requirements. Every addition is engineered to blend seamlessly with your home's existing structure.

Consultation & Vision

We start with an in-depth consultation regarding your family's space requirements, budget, and property limits. Our team visits your home in Alexandria or Northern Virginia to evaluate lot setbacks, existing foundation conditions, structural framing, and zoning feasibility for ground-floor or second-story expansions.

Design, Zoning & Permitting

No need to hire a separate architect or structural engineer. We develop full 3D architectural plans and engineering drawings in-house. We handle the entire permitting process with local building departments in Alexandria, Arlington, and Fairfax County—securing zoning variances, building permits, and environmental reviews before work begins.

Structural Construction

Our Class A team handles heavy construction: excavation, footings, foundation pouring, floor framing, load-bearing beam installation, exterior cladding, and roofing tie-ins. Once the shell is weather-tight, our licensed trades complete rough-in plumbing, electrical, HVAC extensions, drywall, and custom interior finishes.

Final Walkthrough & Warranty

We conduct a thorough final inspection together, ensuring every structural detail, insulation layer, exterior transition, and cosmetic finish meets our strict Class A standards. Your investment is protected by our comprehensive Workmanship Warranty and structural warranty for total peace of mind.

How much does a home addition cost in Alexandria, VA?

Most home additions in Northern Virginia run between $150 and $550 per square foot, depending on whether you're building out (a ground-floor extension) or building up (a second-story addition). Building up typically costs more because it requires foundation reinforcement, roof removal, and staircase modifications. We provide a detailed, itemized estimate after a full structural evaluation of your home, not a generic per-square-foot guess.

Why do home additions cost more in Alexandria than the national average?

Northern Virginia carries a 25 to 40% premium over national averages due to skilled labor shortages, dense clay soils that require reinforced foundations, and some of the strictest building codes in the country. Older homes also often need hidden upgrades (panel updates, plumbing rerouting, structural tie-ins) before an addition can even begin.

What "hidden" costs should I budget for beyond the square footage price?

Tying a new structure into an older home's frame, roofline, electrical panel, and plumbing typically adds $15,000 to $25,000 to a project regardless of size. This is especially common in the older housing stock of Del Ray, Rosemont, and Old Town, where original framing and wiring rarely meet current code. It's why we walk every home in detail before quoting, so you don't get hit with surprise change orders mid-project.

Do I need a permit for a home addition in Alexandria?

Yes. Any home addition requires a full permit package, including Building, Electrical, Mechanical, and Plumbing, submitted through the City's APEX permitting system. We manage the entire submission and inspection process for you, so you're never left navigating city departments on your own.

How long does the permitting process take?

Depending on scope and current department workload, permitting typically takes 8 to 12 weeks. If your home falls under historic review or an HOA architectural committee, add another 2 to 3 months on top of that. Starting design in the off-season (fall or winter) is the best way to be ready to break ground by spring.

Is my home in a zone with extra restrictions, like FAR, setbacks, or historic review?

Possibly. Alexandria enforces Floor Area Ratio (FAR) limits and minimum setbacks from property lines citywide. Homes in Old Town and Parker-Gray carry the added layer of Board of Architectural Review (BAR) approval for any exterior change visible from a public street, while narrower lots in Del Ray and Rosemont often bump against setback limits on second-story additions. We calculate your lot's FAR and setback limits and handle BAR applications as part of our design process.

My neighborhood has an HOA. Do you handle that approval too?

Yes. Communities like Cameron Station, Parkfairfax, and Kingstowne have their own Architectural Review Committees with their own timelines and material requirements (Cameron Station's ARC, for example, meets monthly). We prepare the full drawing and material package your HOA requires and manage the approval process alongside your city permits.

Will I need to move out during construction?

In roughly 90% of projects, no. We isolate the work zone with temporary partitions and dust barriers so the rest of your home stays livable, whether that's a rambler in West End or a townhouse in Old Town. For projects involving a full second-story addition or a complete roof removal, we'll walk you through exactly what to expect before construction starts.

How do you prevent the "change order" surprises I've heard about?

Before we sign a fixed-price contract, we conduct a full structural and code-compliance audit of your existing home, checking framing condition, wiring, plumbing, and foundation. This is how we catch what a surface-level estimate misses, so your price reflects the real scope of work, not a lowball number that grows once demolition starts.

Is a home addition a good investment compared to moving?

Given current mortgage rates and Northern Virginia's tight housing supply, expanding is often more cost-effective than trading up, especially in sought-after areas like North Ridge, West End, and Kingstowne. Additions like a family room or finished basement typically recoup 60 to 75% of cost at resale, while a second-story or in-law suite adds substantial value and lets you keep your existing mortgage rate and neighborhood.

Do I need to hire a separate architect, or do you handle design in-house?

We handle architectural drafting, structural engineering, and construction under one roof. This design-build approach means you deal with a single accountable team instead of mediating between an outside architect and a separate contractor, one of the most common sources of delays and finger-pointing on addition projects.

What happens after construction? Is there a warranty?

Every project ends with a detailed final walkthrough covering structural work, insulation, exterior tie-ins, and finishes. Your addition is backed by our workmanship warranty, so any issue that surfaces after completion is covered, not something you have to chase down on your own.

Every lot in Alexandria and Northern Virginia has unique zoning setbacks, height limits, and structural requirements. Whether you are adding a second story, building a main-level primary suite, or planning a custom room addition, we deliver complete clarity from day one. Schedule an in-home consultation with our Class A design-build team to review your lot boundaries, architectural options, and project budget.
