Home additions in Knoxville

An addition gives you more house without leaving the neighborhood you chose. We build new rooms, second stories and extended footprints that match the house they join.

What the work involves

An addition is new construction attached to an existing house. It starts with the ground: footings or a foundation, then framing, roofing and the tie-in to the existing structure. From there it gets the same work as any finished room, including insulation, drywall, flooring, windows, trim and the plumbing, electrical and heating and cooling it needs.

The hardest part is usually the joint between old and new. Rooflines, floor heights, siding and trim all have to line up so the addition reads as part of the house rather than something bolted on.

Signs it is the right project

How we run it

We walk the property with you, look at where an addition could go and how it would connect to the house, and come back with a written estimate. No work starts until you have signed off on the scope and price, and the contract sets the scope and schedule in writing.

Your project team sends progress updates every week through foundation, framing, dry-in and finishes. When the work is done, we do a final walk-through together, and nothing is finished until every punch list item is closed.

What drives cost

Size is the starting point. After that, the foundation type, how the roof ties in, and whether the existing structure needs reinforcement matter most. A second story asks more of the house below it than a ground-level room. Adding a bathroom or kitchen space means running plumbing, which costs more than a bedroom or den. Finish choices, windows and exterior materials matched to the existing house all play a part.

Permits and inspections are part of the plan for any addition, along with site work. We discuss each of these in the estimate.

East Tennessee lots

Many lots around Knoxville, Powell, Karns and Blount County are sloped, and that shapes an addition from the ground up. A slope can mean a taller foundation wall, a walk-out lower level or extra attention to how water drains away from the new work. In our humid summers, keeping water out of the foundation and the tie-in to the old roof is a big part of building an addition that holds up.

How long it takes

It depends on scope, the site and inspections along the way. Your schedule is set in the contract, and weekly updates keep you current on where the build stands.

What the work covers

Common questions

Should I build out or build up?

It depends on the lot, the structure and what you need the space for. Building out needs yard and setbacks; building up needs a structure that can carry the load. We look at both when we walk the property.

Will the addition match the rest of my house?

That is the goal of every addition we build. Rooflines, floor heights, siding, trim and windows are planned to line up with what is already there.

Are permits needed for an addition?

Yes, additions involve permits and inspections. They are handled as part of the plan for the job, and we go over what yours requires in the estimate.
