Greyrock Concrete Design, LLC, is an innovative artisan concrete studio based in Fort Collins, Colorado. Our team at Greyrock produces high quality, hand-formed concrete, custom designed and built to suit your needs. From our fully-equipped Fort Collins studio, we have the capability to craft our pieces for clients in Denver, Boulder and beyond, offering worry-free delivery and professional installation wherever your project is.
At Greyrock, we live for decorative concrete design. We’d be happy if we never made the same concrete piece twice. It’s the creativity of the design process and then the challenge of turning that design into a reality that makes us love our work so much.
Why We Love Concrete
Concrete’s versatility makes this material stand out over any other solid surface. Our decorative concrete design will always be custom because we handcraft our molds to form your piece. Whether it’s your new kitchen countertop top, integral sink, kitchen island, or vanity for your bathroom remodel—you get the design of your dreams.
Custom to your home, your needs, your creative ideas and preferences, our product will be an asset to your bathroom, bedroom, family room, kitchen, back patio, or any other room in your home.
Custom concrete starts with the design. From sketchpad to blueprint, you will see the idea transform into an original, final product—exactly as you imagined it. Contact us to get started.
The Greyrock Team
Owners Steve Gartner and Greg Kueneke are consummate craftsmen. They believe strongly in concrete as a uniquely decorative, low impact, utilitarian and diverse medium. With a solid reputation as fair and flexible businesspeople, these artisans are in demand. They shape their favorite medium into Concrete Countertops, Concrete Sinks, Concrete Vanities, Outdoor Kitchens, Concrete Fireplaces, Concrete Furniture, and stand-alone architectural features.
The hallmark of their design work is that the eye is drawn to a singular point of visual interest in a room or environment. And it’s always made of concrete.
