Bump-outs and single-room additions: the entry point
A bump-out extends one room — two to ten feet for a kitchen eating area, a bay, or the closet-and-bath space a primary bedroom always needed. Because the roof and structure changes are modest, bump-outs sit at the bottom of the range and deliver an outsized quality-of-life return. A full single-room rear addition (family room, sunroom, home office) adds a foundation, a roof tie-in and full systems, landing mid-range depending on finish.
Rear additions and primary suites: the Maryland favorite
The most common big project we build is the rear addition carrying a family room below and a primary suite above — or a ground-floor suite for aging in place. Two levels of finished space on one foundation is the most cost-efficient square footage in the category. Kitchens inside additions push the number (plumbing, cabinetry, counters), as do masonry exteriors matched to an existing brick house.
Second stories: when the lot says no
Where setbacks, lot coverage or a beloved yard rule out growing sideways, we grow up. A second story needs structural verification of the existing framing and foundation, a temporary roof plan, and stair geometry solved early. It is the most engineering-heavy type and prices accordingly — but in land-tight neighborhoods from Berwyn Heights to Catonsville it is often the only way to double a home in place.
What moves any addition price
Foundation conditions, how the new roof marries the old, the systems the addition carries (a bath or kitchen inside costs more than a bedroom), and finish level. Permit and design come first in our process, so the fixed price we sign reflects your lot and your house — not a per-square-foot average.

Frequently asked questions
Is an addition cheaper than moving?
In most Maryland cases, yes — once you count agent commissions, moving costs, transfer taxes and the price difference of the next house. An addition also keeps your lot, schools and commute, which is why most clients choose it.
How long does a home addition take?
Typical construction runs 14–22 weeks after permits, depending on size and whether a kitchen or bath is inside. Design and permitting happen before that, on their own written schedule.
Do I need an architect for an addition?
Our design-build process includes the drawings and engineering your county requires for permit. For highly custom architecture we can also build from your architect's plans — the permit package is handled either way.
