Stop in for a cup of coffee

didn't you say lean-to? does a 18 X 32 still qualify as a lean-to?
I want to drill some 10in footers and use sonotube for each 6x6 post. Then just attach a ledger board on the building. Leave it open at first , with the ability to close it in later. Want it to match my building. I think I can get this up for less than 2k.
