Huge tech companies have long carved out their turf in Silicon Valley. Apple has Cupertino. Google has Mountain View. Facebook has Menlo Park.
But as those behemoths keep expanding, their offices are spilling into other parts of the region. One of the most desirable new spots is Sunnyvale, a once-sleepy orchard turned suburban city that abuts Mountain View and Cupertino. Google and Apple, bursting out of their hometowns, have gobbled up vast amounts of space in the past few years, and Facebook too has recently leased more than 1 million square feet of space, according to CoStar Group, a firm that tracks real estate trends.
