Being trailer trash, I don't have a garage but I do have a shed.
My shed is 30 years old and made of wood - which is practically unheard of in that it actually is still standing. It is also in damn fine shape for its age, neatly organized, very functional/versatile, and stores an amazing amount of stuff for how large it is (10x12).
Four snowblowers, 2 push lawn mowers, couple chain saws and a pole saw, gas weed trimmer, 3000 psi power washer, two big roller toolboxes, table saw, miter saw, carpentry/plumbing tools/stuff, shovels/rakes/brooms/shears, vice on a workbench, nuts/bolts/fasteners/electrical organizers, extension cords, couple road bikes, all the fluids/oils supports stuff, extra vehicle/OPE parts, my Weber grill, 33 gallon air compressor/air tools stuff...I could go on.
Lots of shelving (OPE is stacked 3 on top of 4, with ramps), lots of stuff hanging on the walls. Think of the interior as a walk-in closet - everything is on 3 sides. I can walk around freely inside where most all the actual work I can do inside the shed - a little tight, but I can move stuff outside if I need a little more room for a quick project.
And oh yeah, it's heated and has a small stereo. Doesn't leak a drop, seals up tight, no varmints/bug getting in.
VERY organized, everything has its place. I need something, I know exactly where it is. What can I say? I know how to fix things - and one doing things like this needs the right stuff to do so.
People that have seen it just shake their head in amazement that I fit all that stuff into it. I hear "FOUR SNOWBLOWERS??????" a lot
Yeah, I'm selling a couple of them eventually - just have never gotten around to it yet.
And everything works perfect - and maybe tops 10% of the contents is newer than 20 years old. Just because it's old doesn't mean it isn't still useful.
