Indicators that a house is well-suited for building a darkroom

[pbromaghin]

If you're thinking about outbuildings as a possibility, a trailer like an Airstream will work
but to go whole hog, find a military surplus portable darkroom. Just add enlarger & go to town.
You should find a picture online

There's one on eBay now for over $5k.

I've had a dry darkroom in an unused bedroom, built a darkroom in a basement, and used the dining room in my last 2 apartments. The best was the purpose built room. If you want to build one look for ceiling height, power, and of course access to plumbing. Do not overlook heating/cooling for comfort.
