Elon Musk’s Boring Company continues to gain validation from city governments. In June, the company was selected to build a multibillion-dollar rapid transit link between downtown Chicago to O’Hare International Airport, and just this week, it got approval from the Hawthorne City Council in California to start building a prototype garage that would transport cars to an underground hyperloop.

The garage will be built on a private residence near SpaceX’s headquarters, which will be rented by the company. The Mercury News reports that, as part of the conditions of the approval, the test elevator will be closed to the public, and no cars will be able to move from the garage to the street in order to keep the project from impacting traffic. Instead, cars must start at SpaceX HQ and stay in the one-mile stretch of tunnel between the residence garage and the company. A sketch of the prototype, seen above, shows an elevator shaft that would lower cars into the tunnel that connects to the hyperloop. More than 100 residents have been notified of the project and assured that the noise would be minimal, but it’s to be seen how quiet drilling tunnels will actually be.

In addition to confirming the news, Elon Musk tweeted today that the first Boring Brick store will be opening in about two months. The bricks, made from the dirt that’s excavated from the tunneling projects, will cost 10 cents each, or they’ll be free if used for affordable housing projects, Musk said. The store will also be shaped like a medieval watchtower, so uh, look out for that.
