minimum polebarn size

allright people, i know this has been asked a thousand times, but this time it is for my personal application, so here it goes again


what is the smallest size polebarn i should consider?


by winter, my oldest will be taking driving classes and we'll need another spot to park another car
so, im hoping to build a polebarn

off the top of my head, i want to put a trailer in there (small, 4x8) his car in the summer, and mine in the winter, so a charger or duster and my ride on lawnmower

i would like to move my workbench and tool box out there (and when i say "i" i mean, my wife wants me to clear the garage from anything that isnt a car)

i dont want to move the bikes in there, but i might have to tear down the shed they are in to make room for them


so, what should i look for?
