I don’t watch a lot of his videos so I don’t know if he has ever explained where he got the brick background. But it looks similar to the diorama’s people make out of pink foam board/sheets so I would guess that it’s a custom piece that he either made or commissioned.

For pieces that you can buy, some Diamond Select’s Gotham figures came with alley way diorama pieces. Also, their recent Ghostbuster figures are including pieces to build the facade of the firehouse from the movies.

Neca released a street/building diorama with their SDCC exclusive Ninja Turtles set this past summer. However, a cleaner, non-TMNT version of the diorama will be released next year for the general public. This diorama is huge so look at some reviews so that you know what you are getting.

There are also cardboard dios from Extreme Sets. They provide a variety of locations like alley ways, haunted houses, etc.

Most of these options can be purchased from BBTS or EE.
