Outside Hangar 3 on Treasure Island, where the Google Barge was constructed, several shipping containers that appear to either be intended for a second structure, or for some similar purpose, sit unattended and unfinished.
It is almost certain that the Google Barge was built inside Hangar 3 on Treasure Island in the San Francisco Bay. Here, equipment sits outside Hangar 3, though it is unknown if the gear is going to be built into a second structure or used for some other purpose.
