Home Additions in Falls Church, VA
Commonwealth Home Design has been designing home additions for Falls Church families for 40 years. Falls Church is really two places: the independent City of Falls Church with its own permitting process, and Falls Church addresses that fall under Fairfax County. Every addition starts with confirming which side of the line the home sits on, and we handle both.
Falls Church has a housing story that spans nearly a century, from Broadmont and Hillwood inside the compact City to Fairfax County neighborhoods with mid-century ramblers, brick colonials, and postwar Capes. Homeowners here want additions that make the good bones work for today’s families without erasing the character that drew them to the home in the first place. Here is what Falls Church homeowners ask us for most:
- Kitchen & Family Room Expansions. Opening up mid-century floor plans and postwar Cape layouts to create the connected kitchen, family, and dining flow modern life calls for.
- Second-Story and Bump-Out Additions. Falls Church’s smaller ramblers and Capes often have room to add up rather than out. A second story doubles the living space without changing the footprint.
- Primary Suite Additions. A dedicated owner’s suite with the closet, bath, and quiet most older Falls Church homes weren’t originally designed to include.
- In-Law Suite Additions. Independent living space with a private entrance, designed for multigenerational families in Falls Church’s established neighborhoods.
- Sunrooms & Screened Porches. Three-season and four-season rooms that extend usable living area without the scope of a full structural addition.
From Our Falls Church Portfolio
Our Whole-House Remodel and Garage Addition project reflects the kind of transformative work Falls Church’s mid-century and postwar homes often need: reconfigured floor plans, expanded living spaces, an updated exterior, and a new garage addition tied cleanly into the existing architecture.

Why Falls Church Homeowners Choose Commonwealth
- Design and construction under one roof. Architects, permitting, and construction stay integrated from concept through completion. No handoffs between designers and contractors, and no gaps between drawing and building.
- Two permitting systems, one process. The City of Falls Church has its own building department and its own code. Fairfax County uses a separate system. We know both and handle whichever applies to your project.
- Detailed estimates before construction begins. Design and pricing are settled before demolition so there are no month-three surprises when it’s too late to adjust.
- Daily onsite presence. A dedicated project manager owns the schedule, and a member of our team is onsite every day of active construction.
Building Additions in Falls Church
Falls Church has two permitting authorities, and we work with both.
Falls Church is really two places. The independent City of Falls Church covers about 2.2 square miles and has its own government, its own permitting office, its own zoning code, and its own review timelines. Neighborhoods like Broadmont and Hillwood sit inside the City. Properties with a Falls Church mailing address that fall outside city limits are governed by Fairfax County, which uses a completely different permitting system through Land Development Services. We confirm jurisdiction at the start of every project and handle all permitting, plan review coordination, and inspection scheduling regardless of which side of the line your home sits on.
Frequently Asked Questions: Falls Church, VA Home Additions
How long does a Falls Church home addition take?
Most Falls Church additions run 3 to 6 months of construction once permits are issued. Design and permitting add another 2 to 3 months on the front end, and City and County timelines can vary. Every project gets a written schedule at the start.
What permits do I need for a Falls Church addition?
It depends on which side of the line your home sits on. Properties inside the City of Falls Church go through the City’s own permitting office. Falls Church addresses in Fairfax County go through the county’s Land Development Services. Both systems have their own timelines, codes, and requirements. We confirm jurisdiction on day one and handle all permitting from there.
Can I stay in my home during an addition?
Yes, in most cases. We plan construction phasing to keep your home livable throughout, working from the exterior and finishing rooms in stages. Second-story projects may require short temporary relocations, which we flag upfront.
How do you match the addition to my existing home?
Our architects study your home’s roofline, materials, window rhythm, and proportions before drawing anything. In Falls Church, that might mean matching a mid-century rambler’s roofline, blending a colonial’s brick pattern, or working with a Cape Cod’s proportions. The addition should read as part of the house, not an obvious add-on.
