I made a quaint little Laundromat when I had some free time, so I thought I’d share the result. Mostly just a flavor addition, but whatevs. If anyone wants to PR this on Git, go ahead, I was going to but I got a lot of stuff going so I couldn’t devote enough time to figuring the git out. Have a nice day, folks 
To “install”:
Create a new .json file in your “data/json/mapgen” folder and paste the following text into it. This file will be the layout of the Laundromat building.
