Custom Home Additions Across Northern Virginia
Timeless Builder Group designs and builds home additions that look like they were always part of your house, matched rooflines, seamless siding, and finishes that flow from the original structure into the new space. As a full-service home remodeling and custom home building contractor, we handle everything from the first sketch to the final walkthrough, so your project stays with one accountable team from permit to punch list.
Whether you need more room for a growing family, a first-floor suite for aging parents, or a bright new space to gather, a well-planned addition is one of the smartest investments you can make in your Northern Virginia home.
Types of Home Additions We Build
Room & Bump-Out Additions
Add square footage where you need it most, an expanded kitchen, a larger primary bedroom, or a dedicated home office. Bump-outs are a cost-effective way to gain space without the footprint of a full wing.
Second-Story & Multi-Room Additions
When lot size is limited, we build up. Second-story additions add bedrooms, baths, and living space while preserving your yard.
In-Law Suites & ADUs
Private, code-compliant living quarters with their own entrance, bath, and kitchenette, ideal for multi-generational households or rental potential.
Sunrooms, Garages & Living Space
Four-season sunrooms, attached garages, and family-room expansions that extend how you live in your home year-round.
What a Home Addition Costs in Northern Virginia
Home additions in Northern Virginia typically range from $50,000 to $150,000 or more, depending on scope. A modest bump-out sits at the lower end, while a full second-story addition or a complete in-law suite with its own kitchen and bath reaches the upper range. The main cost drivers are square footage, foundation and structural work, whether you are adding plumbing and mechanicals, and your choice of finishes.
Because an addition ties into your home鈥檚 foundation, framing, and systems, an accurate quote starts with a site visit. After we review your goals and the existing structure, you receive a fixed, itemized proposal, and financing is available if you would prefer predictable monthly payments.

Frequently Asked Questions
How much does a home addition cost in Northern Virginia?
Most additions range from $50,000 to $150,000 or more. A bump-out is the most affordable option, while a second story or a full in-law suite with a kitchen and bath costs more. Square footage, structural work, and finishes drive the price, and we quote a fixed number after a site visit.
How long does a home addition take to build?
A room addition or bump-out usually takes about 8 to 12 weeks, while a second-story addition or in-law suite can run 3 to 5 months. Permitting and engineering add time up front, which we manage for you.
Do I need a permit for a home addition?
Yes. Additions require county permits, structural engineering, and inspections. We handle the permitting and engineering so your new space is fully approved and code-compliant.
Can you build an in-law suite or ADU?
Yes. We build private, code-compliant in-law suites and accessory dwelling units with their own entrance, bathroom, and kitchenette, ideal for multi-generational living or rental income.
Will the addition match my existing home?
That is our specialty. We match rooflines, siding, trim, and interior finishes so the new space blends seamlessly with your original architecture instead of looking bolted on.
Do you offer financing for additions?
Yes. You can check financing options in minutes and turn a large project into a comfortable monthly payment, with 0% introductory plans available for qualified homeowners.
Is your workmanship warranty transferable?
Yes. Our 2-year workmanship warranty transfers to the next owner, which adds value if you sell your home after the addition is complete.
