About Us
Custom Van & Trailer
Conversions
Built by hand in San Diego, California.
Our Story
How This Started
At the end of 2023, our founder Andrew left a stable career in tech. His daughter Emery had just been born, and the priorities shifted overnight — more time with family, more time building things that matter, and a lot more time outside.
Emery went on her first camping trip at two months old. The family hasn't slowed down since.
That restless energy became Emery Custom Builds — a shop dedicated to turning empty vans and trailers into fully custom, hand-built adventure vehicles. Every build that rolls out of our San Diego shop is designed around how our clients actually plan to live, travel, and explore.
We named the company after the person who started it all. And we bring that same personal commitment to every single project.
Our Approach
How We Work
These are the core beliefs that guide our work. We've outlined our full 5-step process so we never leave you guessing.
Quality Over Speed
Every van is hand built. We don't cut corners, and we don't rush. Our builds take time because we do them right — and you'll feel the difference the first time you open a cabinet door or flip a switch.
Built for Real Life
We don't build showpieces that fall apart after a weekend. Our conversions are designed for the real world — washboard roads, beach parking lots, mountain passes, and everything in between.
No Surprises
You'll know exactly what your build costs before we start. We walk you through every line item, every material choice, and every tradeoff so there's nothing unexpected at the end.
Personal Service
You're not a ticket number. When you work with us, you work directly with the person building your van. We answer your calls, send you build updates, and make sure every detail matches your vision.
Founder & Builder
Andrew Underhill
Andrew is the founder, lead builder, and the person you'll talk to when you call. Before starting ECB, he spent years in the tech industry — but building things with his hands was always the real passion.
When Emery was born, the path forward became clear: build a business around craftsmanship, family, and the outdoors. Today, Andrew handles every consultation, designs every layout, and oversees every inch of every build that comes through the shop.
"Every van is hand built. It isn't fast, and it isn't cheap. But it's awesome."
What We Build
Every Platform, One Standard
Location
San Diego, California
Our shop is in North County San Diego. We work with clients across SD, Orange County, Los Angeles, and the Inland Empire. Most of our clients are in Southern California, but we've had people ship vans from out of state for builds.
If you're not local, the process works the same — we do more of the design and planning over video calls and send more photo updates. The door is always open if you want to swing by the shop during your build.
Andrew's first vehicle conversion — adding a bed and pull-out drawers to his 2004 4Runner.
