Christian Boone — Owner, Fifteen Construction
Born & raised in Knoxville, TN
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.
10 years of engineering experience means every detail is planned, measured, and executed correctly the first time.
Born and raised in Knoxville — this is my community. I build here because I live here.
Detailed scopes, honest timelines, no surprises. You'll always know exactly where your project stands.
We don't try to do everything. We focus exclusively on custom home builds and additions — giving every project the full weight of our experience, attention, and craft.
Your land, your vision, your life — built from the ground up. We collaborate from first sketch to final walkthrough with no compromises on materials, timeline, or execution.
From a detached garage to a full second story — we expand your home in ways that look and feel like they were always part of the original design. Every scope, every size.
Building a custom home is the largest investment most families make. We make the process clear, straightforward, and as stress-free as possible.
We learn about your goals, timeline, and budget to confirm we're the right team for your project.
We walk the land or existing home and build a detailed scope with a real preliminary estimate.
Final drawings, selections, permits, and a locked budget — before a single nail is driven.
Regular updates, site access, and direct communication with your project lead throughout.
We walk every detail with you. Keys don't change hands until everything is exactly right.

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.
