you pm'd me about mine, its same as yours in size, 24x36. I wanted to go 24x40 but set-back from the lane took 4'. Still, I have enough room to put 4 cars, with room to work around them, benches down one side and equipmnt down the other.
My only 'regret' (hard to call it that really!) is that i bought TOO BIG of a lift. I bought the BP HD9-XTW (Xtra tall and wide), when the HD9-S (Standard height & width) would have sufficed and I would be having to work around the posts all the time.
Another change I can still make, is to use post-mounted OH Door openers. The ceiling mounts take up a lot of real-estate above your lift, etc!
