>>3203527Well underground ones aren't, I've never been in a house with one. As shown this is the entry to my laundry on the first floor where I develop my film, as you can see the walls to the back of the house is made of like polycarbonate or something similar. It's thin so it lets in a LOT of light in the day so I'd have to patch the whole back wall but I still don't have any room under my house since it's used as storage/laundry/my brothers recording room. Gonna try find a local darkroom I think
