Born and built inEast
Tennessee.
I'm Christian Boone — owner of Fifteen Construction and a Knoxville native. With 10 years in engineering and a lifetime of roots in East Tennessee, I started Fifteen Construction to bring a level of precision and accountability to residential building that this area deserves.
We're not a volume builder. We take on the projects we can do exceptionally well, and we see every one of them through from the first conversation to the final walkthrough.
Engineering-backed precision
10 years of engineering experience means every detail is planned, measured, and executed correctly the first time.
Locally rooted
Born and raised in Knoxville — this is my community. I build here because I live here.
Full transparency
Detailed scopes, honest timelines, no surprises. You'll always know exactly where your project stands.

Common Questions.
Everything you need to know before starting your custom home or addition project in Knoxville.
Yes — custom home builds are the core of what we do. We work throughout Knoxville, Farragut, and Knox County, partnering with your architect or ours to build a home designed entirely around how your family lives. Every build is ground-up and fully custom.
We build the full range of residential additions — home extensions, primary suite additions, second story additions, detached garages and workshops, decks and outdoor living spaces, sunrooms, and screened porches. If it expands your home, we build it.
Cost varies based on square footage, site conditions, design complexity, and finish selections. We provide detailed, transparent estimates after an initial site and scope consultation — no vague ballparks. Contact us to discuss your budget and vision and we'll give you an honest picture of what's possible.
Most custom home builds in East Tennessee take 10 to 18 months from groundbreaking to move-in, depending on size and complexity. We lock in a detailed schedule during the design and planning phase — before construction begins — so you know exactly what to expect.
Yes. Fifteen Construction is a fully licensed general contractor in the state of Tennessee and carries full general liability insurance and workers compensation coverage on every project we take on.
