Home Additions in Reston, VA
Commonwealth Home Design has been designing home additions for Reston families for 40 years. Reston is unusual in Northern Virginia. Its planned community structure, seven villages, and Reston Association design review mean every addition needs a design that reads the community’s architectural language and gets through DRB review the first time.
Reston’s housing story spans six decades. Contemporary and mid-century clusters around Lake Anne. Split-foyers and colonials through South Reston and Hunters Woods. Larger colonials in North Reston. Wooded lots, cluster properties, and single-family homes with unique remodeling considerations that come from a planned community. Here is what Reston homeowners ask us for most:
- Sunroom & Screened Porch Additions. Three-season and four-season rooms that take advantage of Reston’s wooded lots and trail-adjacent settings. Popular on both single-family and detached cluster homes.
- Family Room & Kitchen Expansions. Opening up 1970s and 1980s floor plans where kitchens and family rooms sit in separated boxes. Reston homes benefit enormously from expanded, connected main living space.
- Primary Suite Additions. Dedicated owner’s suites in homes that were built with modest primary bedrooms. Often paired with private outdoor space that Reston’s wooded lots make possible.
- In-Law Suite Additions. Independent living space with a private entrance, designed for multigenerational families in Reston’s larger detached homes.
- Second-Story and Bump-Out Additions. When a rambler or split-foyer has good bones on a good lot, adding upward or expanding at the back can transform the home without a full whole-house remodel.
From Our Reston Portfolio
Our New Sunroom project shows the kind of addition work Reston homeowners ask for most: a bright, light-filled room built around a dramatic wall of windows that brings the wooded setting inside. Reston’s mature canopy and lakefront properties make sunroom and screened porch additions especially popular here. Get the full project details.

Building Additions in Reston
Reston additions go through two reviews, and we handle both.
Reston is unincorporated Fairfax County, so building permits, mechanical, electrical, plumbing, and site work all run through Fairfax County’s Land Development Services and Building Division. Reston also has the Reston Association Design Review Board (DRB). Any exterior modification visible from common areas, additions included, needs DRB approval before construction can begin. The DRB reviews for compatibility with the neighborhood’s architectural character and Reston’s covenants. For homes in cluster communities, individual cluster covenants may add another layer. Working with a firm that knows both systems means the design gets approved and built without wasted revisions.
Frequently Asked Questions: Reston, VA Home Additions
How long does a Reston home addition take?
Most Reston additions run 3 to 6 months of construction once permits are issued. Design and permitting typically add another 2 to 3 months on the front end, and DRB review can add time depending on the queue. We start the DRB submission early to keep the overall timeline on track.
What permits and design reviews do I need for a Reston addition?
Reston additions need Fairfax County building permits and Reston Association Design Review Board (DRB) approval for any exterior work. If your home is in a cluster community, individual cluster covenants may add additional requirements. We handle the full permit and design review process end to end.
Can I stay in my home during an addition?
Yes, in most cases. We plan construction phasing to keep your home livable throughout, and Reston’s cluster and single-family homes are usually straightforward to work around. Extended relocations are rare but sometimes needed for major roof or foundation work.
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 Reston, that means matching the specific vocabulary of the era and village your home came from, whether that’s Lake Anne’s contemporary lines, a Hunters Woods split-foyer, or a North Reston colonial. The addition should belong in the neighborhood.
