FREQUENTLY ASKED QUESTIONS
A few of the questions we hear most often about architectural cast stone and working with COBO.
Why use architectural cast stone instead of natural sandstone? Natural sandstone is beautiful, but it comes with limitations — you get what the quarry produces. Architectural cast stone can be molded, colored, and textured to precise specifications, which makes it far more adaptable across project types. It's also generally less costly than quarried stone, without compromising on appearance or durability.
I have an idea, but I'm not sure how to move it forward. Can COBO help with the design?
Yes. If you have a rough concept that needs to be developed into a buildable spec, our co-design process can get you there. If you're coming in without a design at all, we can create something from scratch based on your space and project requirements. The first step is just reaching out to talk through what you're working on.
What colors and finishes are available?
COBO produces a wide range of custom shading using white and gray Portland cement, sand, and pigment additives. All finishes fall within three primary color families: White, Buff Sandstone, and Bohemian — a distinctive greenish-grey. If your project requires a specific tone, we can develop a custom mix to match.
Can I request a sample of the material?
Absolutely. Call or email us and we'll get a sample out to you so you can evaluate the color, texture, and finish before committing to a project.
What kinds of projects does COBO work on?
Residential and commercial, interior and exterior, restoration and new construction — the range is broad. We're comfortable with everything from intricate ornamental detailing to large decorative elements. We also work with plaster of Paris in addition to cast stone, depending on what the application calls for.
We're based outside of Colorado. Is that a problem?
Not at all. The majority of our clients are along the Colorado Front Range, but we do travel for the right project. Qualified architectural cast stone craftsmen are difficult to find — if you're not able to source this level of work locally, we're happy to discuss what a project outside Colorado would involve.
