MENLO PARK, Calif.--Mark Zuckerberg is moving into Scott McNealy's old digs.

Later this year Facebook will move into the nearly vacant office complex formerly home to Sun Microsystems near the foot of the Dumbarton Bridge, Chief Financial Officer David Ebersman announced today at Menlo Park City Hall. The first groups will make the short trek from downtown Palo Alto to Menlo Park starting in June or July, the company said in a press release, confirming what was already fairly common knowledge.

After Oracle acquired Sun, it laid off thousands of employees and started moving others farther north up U.S. 101 to its campus in Redwood Shores, leaving a sparsely populated complex of nine buildings covering 57 acres on the shore of the bay. Sun still has a few employees in the location, but Facebook will take it over later this year. The deal is called a sale leaseback, a 15-year lease from Oracle with an option to purchase the property after 5 years, and the terms were not disclosed.

Facebook will maintain its current presence in Palo Alto, but will call the Menlo Park campus its headquarters. Facebook has 1,400 employees in Palo Alto and 2,000 worldwide, the company said in a press release.

The old Sun campus will give Facebook tons of room to expand, with 3,700 parking spaces and a total of about 1 million square feet in office space. The company looked at several different locations in the Bay Area but "the Sun campus was by far and away our first choice," Ebersman said.

It's just another sign of Silicon Valley's ability to reinvent itself every decade or so. Google's campus in Mountain View was once home to SGI, a giant in computer graphics processing that succumbed to cheaper and more powerful hardware. Tons of smaller start-ups in San Francisco have claimed the old warehouses and storage facilities in the South of Market district as their own.

One open question is whether Facebook's relatively young workforce will embrace a fairly isolated campus surrounded by one of Menlo Park's more troubled neighborhoods, but Ebersman said the company would focus on making the environment "a fun place to be."

About one-third of the campus is fenced off with active construction work taking place, presumably in line with Facebook&39's expectation that it will be able to move in by June or July.
