After less than a year providing co-working space for Santa Monica entrepreneurs, Cross Campus is upgrading to a larger office.

Cross Campus has signed a long-term lease for a 13,000 square-foot-property at 10th Street and Colorado Avenue. Its current office is two blocks away at 820 Broadway.

The company expects to move its co-working members into the space after the first of the year.

The building, which has a bow truss ceiling, was previously occupied by an architecture firm. It has an open floor plan that Cross Campus will renovate to use as collaborative work and event space.

The company plans to add offices and conference rooms near the perimeter of the open space. An attached but separate office will also be remodeled into reserved private offices.

The new building, which is about 30 percent bigger than the current space, will allow Cross Campus to increase its event capacity from about 350 people to about 500.

The company will also expand the size and number of its private offices, allowing for companies of up to 20 people to rent the rooms, up from companies of about 10 people in the current location.

Ronen Olshansky, one of the Cross Campus co-founders, said the firm began looking for new space as it approached capacity at its current location.

"What's great about this is that we'll have a broader inventory of space," he said. "It's great but also frustrating when we bring a member on and they get too big. Now that won't happen. We'll have that inventory to keep those companies in the lifecycle."

Cross Campus opened in Santa Monica last year as a co-working space with a hands-on approach. Olshansky and partner Dan Dato also mentor companies and host events that help them make business connections.

Memberships to Cross Campus range in price from $100 a month to $600 a month. Olshansky and Dato said the company works with hundreds of members, many of them technology startups. But Cross Campus also has members who are writers and creative types.

Jeffrey Chernick, chief executive of transportation technology startup RideAmigos, said he and his co-founder chose to work out of Cross Campus after they tired of spending time at their local coffee shop.

"We never wanted an office space," he said. "I started hearing about co-working places and we visited Cross Campus. That day we signed up. It's cooler because it's a shared space."
