This pear-shaped concrete fire pit was cast from a mold hand sculpted from rigid foam. The design intent was to create a distinct architectural piece for a rooftop lounge.

This custom concrete fire pit for an outdoor lounge on a rooftop in Beverly Hills is like a piece of modern art, designed to be a unique architectural focal point that allows the flames to be viewed from different angles.

“Concrete was chosen for its ability to create unique shapes of any design, such as this elliptical piece,” says Chris Frazer of DC Custom Concrete, who collaborated with architect Wolcott Architecture Interiors to bring the design to life. “Designers are beginning to see the endless possibilities of cast concrete beyond straight lines.”

DC Concrete sculpted the large pear-shaped mold from dense, rigid foam, and then cast the piece using glass-fiber-reinforced concrete made with white cement and enhanced with polymers for additional strength. An oil-based penetrating sealer was applied to the exterior for weather and stain protection. Glass inserts were installed to cover each opening, providing both aesthetic interest and safety from the flames. (See Fire Pit Safety Tips).

Glass inserts provide a safe view of the flames without distracting from the ambiance or warmth of the fire.

Frazer is seeing a growing demand for custom concrete fireplaces such as this one, but admits they can be tricky to fabricate. “Nonstandard shapes use an entirely different process. A specific mold must be created, casting is different, as well as the GFRC technique,” he says. However, Frazer enjoys the challenge of creating one-of-a-kind pieces for his clients, ranging from bathtubs to sinks to countertops. See some of his other custom work:
