The El Cerrito Chamber of Commerce hosted an "Open House" party Thursday night to celebrate its move back to the city's main thoroughfare, San Pablo Avenue.

Though its five-room new home is more than five times bigger than the tiny office it occupied for the past three years at 406 Colusa Avenue, there wasn't a lot of elbow-swinging room amid the crowd that came to Thurday's "Grand Opening Mixer."

The chamber hopes its larger, more prominently located headquarters at San Pablo and Eureka Avenue will serve as "a community hub," chamber manager Mark Scott told Patch. The new space is 780 square feet, compared to 144 at the former space, he said.

In the latest issue of the chamber's Byline newsletter, chamber president Judy Pope wrote, ""Now, back on San Pablo, the Chamber is set to become the focal point for our business community once again."

The chamber's previous long-time home before moving to Colusa Avenue had been a well-known, stone-clad, steeply gabled building at 10848 San Pablo Ave., that had formerly been Contra Costa Florist. The chamber occupied that building from 1991 to Feburary of 2009.

Correction: The original version of this story gave the wrong street name for Eureka Avenue. It has been corrected.
