Our garage is a bit of a mess. It's got a fair few boxes of my son's car parts, and his assortment of messy car tools - he's not organised. I even built a storage shed to get rid of some of his stuff, but he's filled it.
We've got 9 bikes in ours plus four sets of 'spare wheels hung up. The big 'space eater' has been the addition of a full set of camping gear this last year. We had a small amount of stuff, but we've got a big tent, and associated porta potty, electric hookup, leccy heater, leccy cool box. Add in decent camping chairs, camping beds and a blow up paddle board, space is now a premium. It's organised, I just pull everything out, essentials are in one big box, spare stuff in another, but it takes up so much room.
