For over 25 years, Simon Ashley Design Studio has been transforming homes across the St. Louis area. We're not a big-box contractor. We're a design-build studio where every project gets personal attention — from the first conversation to the final walkthrough.
Our certified designer, in-house construction crews, and fully equipped showroom mean you work with one team from start to finish. No juggling architects, designers, and contractors. No surprises. Just a clear vision brought to life by people who care about every detail.
What We Do
Why Choose Us
All Under One Roof
From design concepts and material selections to construction and final finishes — we manage everything in-house. You get one point of contact, one team, and one vision carried through from start to finish. No miscommunication between separate firms. No details falling through the cracks.
Artisan Craftsmanship
Simon's background in art, historical renovation, and the building trades means your project gets something most contractors can't offer: a creative vision backed by hands-on expertise. We design and build custom pieces in-house — doors, metalwork, carved details, and finishes you simply can't buy off a shelf.
Complete Discretion
Many of our clients are high-profile professionals who value their privacy. We've built our reputation on trust, and that includes never sharing project details without permission. Your home is your sanctuary — we treat it that way.
“We've worked with Simon for over a decade now. He did our kitchen, then our basement, and when our daughter bought her first home, she called him before she called us.”
