Sounds like hubby dear has a horder problem. Have you told him that you're afriad you'll break an ankle just trying to get to the freezer? Does he panic at the suggestion that you get rid of the spare toilets? Can you donate any of the construction materials to something like Habitat's Re-use?

If hubby freaks at the sound of getting rid of things, then he'll probably need professional help. There is a point that the hording gets to be a safety issue, and it looks like you might have crossed the line.
