Room Additions in Nashville & Brentwood

What happens, and in what order?

An addition goes through four stages with us, and you know which one you’re in at any point.

Consultation and designDarryl comes out, measures, listens, and draws the room onto your house.
Blueprints and the permitPlans drawn for the codes office, and the permit pulled before any digging.
The buildFoundation, framing, the glass, heat and air where it’s needed, then the finish inside.
After the installWe stay the number you call once you’ve moved in.

What can an addition be for?

A den, a bigger kitchen, a bedroom on the main floor, or something more particular. One of ours holds an indoor swim spa. The addition sits on a stone base with windows on three sides, and the spa is set into a raised slate surround with steps up to it, so the family swims and soaks in January the same as in June.

Is it a sunroom or an addition?

To the codes office, an all-season sunroom on a new foundation is an addition. It’s permitted, inspected, insulated and heated like the rest of the house. The difference is how much of the wall is glass. If you want light most of all, read about sunrooms; if you want a room that looks like the rest of the house from the street, it’s an addition, and we draw it to match the brick or siding, the roof pitch and the windows you already have.

Who handles the permit?

We do. The plans and the permit are part of the job, and nothing is opened up until the permit is in hand. The City of Franklin’s records, for one, show an addition of ours permitted in August 2022. If what you really want is a separate building out back, that’s a detached ADU, and the rules for those depend heavily on your city.

Room addition questions

What steps does a room addition go through?

Four: consultation and design, blueprints and permitting, the build, and care after the install. The build runs foundation, framing, glazing, heat and air if needed, then the finish inside. We design and build, so one company is answerable for every step.

Is a sunroom an addition?

An all-season sunroom on a new foundation is a room addition in every way that matters to the codes office: it is permitted, inspected and conditioned like the rest of the house. The difference is mostly glass. We build both and draw whichever one the space needs.

How much does a room addition cost in Middle Tennessee?

It depends on the square footage, the foundation, the roof tie-in, how much glass, and heat and air. A two-story glass room costs differently from a one-story den. We price from the design after a free consultation at the house, never from a per-square-foot guess.

Do you handle the heating and cooling for an addition?

Yes. The addition is tied into your existing system or given its own ductless unit, decided in the design. Insulation goes in to match how the room will be used, including spray foam where the construction calls for it.

Will the addition match my house?

That is why it is drawn before anything is built. The brick or siding, the roof pitch, the trim and the window style are taken from your house and put on the drawing, so you see how the new room meets the old one and change it there, not after the walls are up.
