Budget Parking Construction Ideas?

[Brian Reinholz]

Hey folks -- I have a 4-plex that I'd like to consider an affordable parking shelter for. I'm hoping there's some middleground between an expensive garage and a cheapo canopy. There's a nice plot of gravel in the backyard where something could be put up pretty easily.

Anyone have any experience building some type of carport that can go up quickly and still handle snow?
