Home Additions
Rear additions, second stories, and bump-outs that match the house
Home Additions in Washington DC, Maryland & Virginia
When there is no room left to reconfigure, the answer is more house. We build rear additions, second-story additions, kitchen and bathroom bump-outs, and enclosed porches — tied into the existing structure, roofline, and siding so the finished addition reads as part of the original home instead of an obvious bolt-on.
Additions are the most permit-heavy work we do, and lot coverage, setbacks, and historic review rules vary sharply between DC, Montgomery County, Prince George's County, Arlington, and Fairfax. We tell you what your lot will actually allow before you spend money on drawings.
What the scope covers
- Rear and side additions on existing foundations
- Second-story additions and dormer expansions
- Kitchen, bathroom, and living room bump-outs
- Foundation, footing, and structural framing
- Roof tie-ins, siding, and exterior matching
- New windows, exterior doors, and trim
- Mechanical, electrical, and plumbing extensions
- Zoning, setback, and permit coordination
Four steps from first call to final walkthrough
Feasibility Review
We check setbacks, lot coverage, and structure to confirm what can be built before you commit to a design.
Design & Permitting
Drawings are produced and submitted, and we manage the review process with your jurisdiction.
Foundation & Framing
Footings, foundation, framing, roof tie-in, and weatherproofing are completed and inspected.
Finish & Walkthrough
Mechanicals, insulation, drywall, and finishes go in, followed by a full punch list and walkthrough.
The difference a careful job makes
Small choices in prep, materials and finish work decide whether a remodel still looks deliberate in ten years — or starts failing in two.
A Finish That Holds Up
Level cabinet runs, tight mitres and tile that lines up across planes. The details that separate a remodel from a repair.
Correct Behind the Walls
Waterproofing, framing corrections and right-sized supply lines. The invisible work decides how the visible work ages.
Priced Before Demolition
A written scope listing what is included and what it costs, agreed before anything is torn out of your home.
A Schedule You Can Plan Around
Realistic timelines with permit review and material lead times built in — not optimistic dates that slip week by week.
Detail-driven from start to finish
Premium results come from disciplined habits, not shortcuts. This is the standard we hold ourselves to on every home additions project.
