About us
Hi, we’re Katelyn & Bradan.
Born and raised in the Treasure Valley, with 10+ years of construction experience and industry resources with 35+ years in the business.
Our story
A personal approach to building and design
Katelyn grew up around custom home building with Holton Homes, her family’s business, owned and operated by Dave and Betty Holton. She later worked as a design consultant with Liberty Enterprises, helping bring custom-home ideas, materials, and finishes together.
Bradan is a project manager with a Boise contractor, where he manages large-scale commercial and industrial plumbing and mechanical projects, with five years in project management as of April 2027. He brings the scheduling, budgeting, and trade coordination that keep a build organized and moving.
We started Brothers Kustom Build & Design to offer a more personal experience, with clear communication and close attention to the details that make a house feel like home. Our goal is simple: a home you enjoy more and can entertain in with ease.
What we stand for
Our commitments
Thoughtful design
A personal approach to layouts, finishes, and function, shaped around how you live.
Clear expectations
Plain language, written scope and pricing, and regular updates. You’ll always know where your project stands.
Quality oversight
We review the work as construction progresses, so every phase meets our standard before the next begins.
Built to your vision
“Kustom” is our promise. No two projects are alike, because no two families live the same way.
