Nothing other than working on the bikes and needing the storage space. My current 20x20 garage is pretty cramped, full of motorcycles, bicycles, and equipment/tools - tire changer, balancer, motorcycle lift, air compressor, tool chests, tire racks, parts washer, the list goes on. It would be nice to park the cars inside for a change, so I'd need a huge shed in the back yard to handle the contents of the existing 10x10 shed along with everything from the garage, plus room to actually move around comfortably. Right now, I have to roll bikes out of the garage and onto the driveway to swap bikes onto the lift. I'd like enough space so that I can move everything around inside, especially in the winter. Plus I'd like space for additional bikes.
So I'd need 500 sq ft just to cover what I already have, and let's say double it for the elbow room and one or two more motorcycle lifts so I can leave long term projects up while still being able to service my or my friends' bikes. That's about a 25x40 or 20x50, and I know one of my next-door neighbors will have a problem with it just because she can, even though I've got plenty of space. So that's where the idea of having a separate motorcycle shop on cheap property with less building restrictions came from, and that property I posted was perfect. The structure is actually larger than I need if its only for the bikes, but hey, you can't even find vacant land for that price. And the longer term plan is to use it for some type of retirement business if I choose to take early retirement in 3 years.
