Now that Nicole is getting to build her darkroom, I thought it would be good to add what we might do differently. Or what was a good thing to include. I'll start, I have found that that there can never be to many ways to turn on the main light. My 4th darkroom had 4 switches. The room was 20 feet long. Nice not to have to walk to the door to turn it on. My 5th darkroom is smaller 9x10 feet. I have separated the developing and mounting areas, which is also great on cutting down on dust. Anyway I figured It wasn't to far to get to the dor (2 Steps) I can not believe how annoying it is to have to go to the door to turn on the light.
