Different feeling here. My barn is over half full of hay and the other has my son's boat and his waverunner and sea do. My John Deere dozer and my new LS XR4150 is setting outside. I am going to have to build him a shed so I can store my stuff. I need a Pepto Bismol and two tylenol.
I believe the Son would be building his own shed for the boat, waverunner and seadoo. My stuff would not be sitting out in the weather. I love my children but I don't operate a storage facility for them.
Hard to do somethings, I might have to sleep with my eyes open or a knife in my back from my wife. We do a lot for our kids. At the time I purchased the 40 x 40 metal building and had it taken down and moved, I also got a 40 x 60 and a 24 x 70 metal buildings. I paid $3000 for all of it. The 40 x 60 may be the next one put up. The frame for it is like new. I plan to use new metal on the roof of it. The 24 x 70 was damaged and it may be put up in different sections. I am using the sheet metal on the sides and for critter pens. You can never have enough sheds.
Storage capacity is always too small. No matter what size you THINK you need and build, it is going to be too small in a couple of years. I think it is human nature to try to fill up a cavity regardless of the size. So if you build to suit one tractor, one boat, one car and one motorcycle at half the overall capacity, eventually you will buy more stuff to over-fill the shed and then need to build more shed.
