Here's Tesla's first Gigafactory, located just outside Sparks, Nevada.
Tesla spent an estimated $4.5 million to build the first phase of the Gigafactory's roof, according to work permits obtained by the Reno Gazette-Journal.
Construction on the roof is mostly complete. Solar panels are coming later, but the white foundation will ensure the roof stays cool, thus optimizing the efficiency of the solar panels.
Still, many large parts of the building are under construction and it looks like Tesla is also preparing the area for another large expansion.

Tesla has spent millions of dollars building the "trailer city" around the Gigafactory, with several hundred thousand dollars spent on building a fire command center and guard shack, according to work permits.
The Gigafactory's foundation alone cost an estimated $16 million.
Last summer, Tesla spent nearly $13 million on the steel and concrete for the building's mezzanine.
The electrical infrastructure for the Gigafactory reportedly cost Tesla about $300,000.
