A family design and remodel studio, rooted in Naperville
Formerly Best Buy Interior Finishes. Mart Design Co. provides design, fabrication, and installation under one roo. Led by and built on more than 30 years of Martinez craftsmanship.
One team, start to finish
A kitchen remodel shouldn't require you to become a general contractor. But that's often how it goes: a designer draws it up, a countertop shop cuts the stone, some other crew lays the floor, and you're the one making sure they all talk to each other. We started Mart Design Co. so that all of it happens under our own roof, with our team.
Led by the family, built by the team
We care about our customers, and about the people who build for them: we've worked hard to be a good company to work for, not just to work with. We believe that care shows in the finished result.
Rooted here, built under one roof
We're part of Naperville. we live here, not just work here, carrying forward family craftsmanship rooted in 1992. And we handle the whole project ourselves: in-house designers, our own stone fabrication and our own install crews, all under one roof. One accountable family, from first sketch to final walkthrough.
Concept to completion, built to last
Our mission at Mart Design Co. is to deliver exceptional, family-focused design-remodel-build solutions for Chicagoland homeowners & businesses by combining honest, personalized service with superior craftsmanship and high-quality materials. We partner with clients from concept to completion to create beautiful, functional spaces—on time, on budget, and built to last.
From the back of a van to a full design and remodel studio
Our story starts more than three decades ago and every step added a craft we still practice in-house today.

Everything under one roof
Today Mart Design Co. is a licensed and registered general contractor offering planning, design, and construction and not just the pieces, but the whole project.
In-house stone fabrication
We laser-measure your countertops and cut them on our own CNC equipment right here in Naperville and then our own crews install them. Two decades of doing it ourselves.
Design that starts with a conversation
Our in-house designers take a project from first meeting to finished room, with realistic 3D renderings before construction begins.
A studio you can visit
Full slabs, floor and carpet samples, real finishes, cabinet doors you can open. Materials you can't judge from a website.
Flooring, cabinetry & remodeling
From a single countertop to a whole-home remodel, one accountable team handles it.
