Wood Construction

For this award-winning warehouse addition, curved glulam beams were used to create a unique undulating roof exposed to the interior office environment. The complex structure was formed with 22 beams ranging in length from 16 to 52 ft (4.9 to 15.8 m). Manufactured with specific curvatures, the beams were beveled on their top edges using a computer numerical controlled (CNC) machine. Supporting rafters were also different—each precisely machined and coded for its particular location in the roof.

Designed to meet stringent wind and seismic requirements, the use of wood also offered other benefits. “We wanted an exposed structure that could be visible from the indoor space, so people could see and understand how the building was made,” said Dolan Daggett of Eric Owen Moss Architects. “Wood allowed us to do that, both aesthetically and economically.”

Project Details

At first glance, the project assignment may have looked ordinary—almost dull. Their job was to add a 6,000-square-foot rooftop addition onto a 1950s-era brick and concrete (CMU) warehouse in Southern California. But designs from the team at Eric Owen Moss Architects are anything but ordinary, so they explored the possibilities and took wood to the edge as they used curved and beveled glulam beams to form the innovative roof.
