Home Additions in Knoxville, TN
Sometimes the house and neighborhood is right and there just isn’t enough of it. Another bedroom. A real primary suite. A kitchen that doesn’t end at a wall. Room for a family that grew.
Gold’s Carpentry builds additions in Knoxville, from foundation and framing through the last piece of trim, with one contractor responsible for the whole thing. We pull the permits, schedule the trades, and stay in charge of the parts that go wrong when nobody is.
And because our own carpenters do the finish work, the new part of your house doesn’t announce itself as the new part. That’s harder than it sounds, and it’s most of the difference between an addition and an addition that looks like one.
Types of additions we take on

Structural work — removing walls, re-framing, re-roofing to tie in
Seamless Additions Built with Excellence
Most additions give themselves away. The rooflines don’t quite agree. The siding is a shade off. The trim inside is close to the original but not the same, and the transition between old and new is a threshold you can feel.
Getting it right is mostly finish work: matching profiles that aren’t sold anymore, carrying a floor through without a break, tying a new roof into an old one so the joint reads as intentional. That’s the part of the job we came up doing.
It also means paying attention to the house you already have. A 1930s bungalow and a 1990s build want completely different additions, and an addition that ignores the house it’s attached to never quite settles in, no matter how well it’s built.
Why Choose Us
Permits & Inspections
We’re a licensed general contractor, and we pull the permits and schedule the inspections. You don’t have to deal with the county.
Drawings
An addition needs real drawings to permit and build from. Occasionally for smaller projects we will draw plans in house, but more typically we will refer you to one of our partnered architects for both architectural and structural plans. These plans will be submitted directly to the county when pulling permits.
We Make Sure it Fits
Every property has setbacks (example: how close you can build to your property lines) and limits on how much of the lot can be covered. Those vary depending on where you are in Knox County, and they occasionally kill an idea outright or push it to a different side of the house. We look at this early, before you’ve spent money or fallen in love with a plan.
Our Process
How We Do Additions
01
First Conversation
You call or write, and we get back to you within one business day. We'll ask enough on the phone to know whether it's worth a visit.
02
On-Site Visit
We look at the space, talk through what you want, and flag anything structural or mechanical that might shape the plan. Bring pictures or ideas you like — they tell us more than adjectives do.
03
Estimate
After you’ve secured drawings from an architect we get you a fixed cost estimate in 5–7 business days. Written, broken out, and based on the scope we agreed on.
04
Permitting
Once you decide to move forward, we get the drawings submitted and the permits pulled. This stage takes roughly 2-4 weeks depending on the complexity of the project.
05
Construction
Foundation, framing, roof and dry-in, then mechanicals, then finishes. You’ll know what’s happening each week and who’s in your yard.
06
Walkthrough & Close
We go through it together, make a punch list, finish it, and clean up properly.
Timeline & Investment
Additions in Knoxville generally run between $50,000 and $300,000, depending on size, foundation and roof complexity, and what’s inside the finished space — a bedroom and a primary suite with a bathroom are very different projects per square foot.
Most additions take two to three months from the start of construction, plus two to four weeks beforehand for drawings and permits. We give you real dates before we break ground.
Home Addition Questions We Get A Lot
How much does a home addition cost in Knoxville?
How long does a home addition take?
Most additions we build run between $50,000 and $300,000. The biggest drivers are square footage, how complicated the foundation and roof tie-in are, and what goes inside — a bedroom costs considerably less per square foot than a primary suite with a bathroom. We can usually tell you on the phone whether your budget and your plan are in the same range.
Construction typically runs two to three months, plus two to four weeks beforehand for drawings and permitting. Weather, inspection scheduling and material lead times all move it. We give you real dates before we break ground and tell you when something changes.
Do I need architectural drawings for an addition?
Do you handle permits and inspections?
Yes. An addition needs drawings to permit and build from. Occasionally for smaller projects we will draw plans in house, but more typically we will refer you to one of our partnered architects for both architectural and structural plans. These plans will be submitted directly to the county when pulling permits.
Yes. We’re a licensed general contractor in Tennessee and permitting is part of the job. We pull the permits, schedule the inspections and deal with the county so you don’t have to.
Can I stay in my house during construction?
Will the addition match the rest of my house?
Almost always. Most of an addition happens outside your existing walls. The disruptive part is opening the wall to tie the two together, which gets scheduled well in advance so you can plan around it.
That’s the goal, and it’s most of what we care about on these projects. Matching means siding, rooflines, window proportions and interior trim (including profiles that may not be manufactured anymore). Our own carpenters do that finish work, which is why we can promise it.
Is it cheaper to add on or to move?
Can you build a second story?
It depends on your house and the market, but an addition is often the better move if you like your neighborhood, your lot and your schools — because moving carries costs that don’t show up in a purchase price. Agent commissions, closing costs, moving, and whatever the new house needs. An addition puts that money into the house you already want to be in. We’ll give you a straight answer if we think you’d be better off moving.
Yes, we can build a second story. As with all additions, we need existing or added foundations to carry the load from the second story down. This is where the architect/structural engineer comes in during the planning phase.
What if there are setback or zoning problems?
We look at that early, before anyone spends money on drawings. Setbacks and lot coverage limits vary across Knox County and they occasionally mean an addition has to go on a different side of the house than you pictured — or that a different approach makes more sense. Better to find that out in week one than week six.
How do we get started?
Call or send a message describing what you’re trying to gain. We’ll get back to you within one business day and set a time to come walk the house and the lot with you.
