Facebook will be building a campus that will house 3,400 engineers in a single building with reconfigurable work and meeting space and a garden that extends from around the building to cover the entire roof of the structure. It will be located on ground already owned by Facebook that sits across the street from its current campus in Menlo Park, Calif., and make use of a tunnel that already links the two pieces of ground.
As for Google, it has other building plans as well.
The company also will be building an $82 million private airport terminal in San Jose, Calif., to accommodate its business jets. It would be an addition to the Mineta San Jose International Airport already located there.
Google also is seeking a greater retail presence with plans to open stand-alone shops in big cities, with the first ones expected to launch in time for the busy holiday shopping season. The idea is to give people hands-on time with current Google devices such as the Chromebook , Nexus 4 smartphone and Nexus 10 tablet and at some point Google Glass.
Not all of Google's buildings are getting positive buzz, however.
Google recently vacated two of its Mountain View buildings because toxic vapors were emanating from the ground. Forbes reported that the leaks in the area where the buildings are located were so bad that the site was designated a Superfund priority.
