We have a large garden shed, that looks like the rest of the house. Instead of gardening tools, our bikes are in there. We each have 3 bikes, plus, my son's Serotta is in there, too. DH's bikes are all hung with hooks, as is my mountain bike. But I can't easily lift the hanging bikes on/off because I am too short, so my road bike and Jamis are in a little 2 bike holder stand.
DH also built a platform with the front tire skewers in the back of his Lexus. He mostly keeps his bike in there during the week, as when he commutes, he's taken to driving to a municipal lot and starting his ride from there, to avoid the climb home.
I haven't even put my bike rack on this year; I just stick my bike in the back of my car, with the seat folded down.
