Hey all, I was looking to see if anyone had any storage suggestion ideas for this Dead space. I have behind my refrigerator. I’m only able to reach in. Probably about 3 ft or so, but the space is about 4 ft wide by 7 ft long. The floor of this space is also the ceiling of my basement, so I can’t see it supporting very much weight without being reinforced. Looking for ideas if you have any, thanks!

I second this. Especially if you’ve the means to vent it appropriately. It will help isolate noise.
And if youre feeling like some minor woodworking… They sell door framing for next to nothing at big box stores… A thinner one would vastly improve your light switch situation ;)
