Hi guys, First time deck-DIYer looking for some help. I'm looking to build a deck off the back of my house, and I have a bump out which is cantilevered from the house. As such, I don't want to put a ledger on it, so my deck is going to be free standing but sit right beside the house. The deck is going to sit 14" off the ground, so my plan is to have the beams sit directly on the cement footings. With respect to the attached design: - Green = beams made of 2 2x10's - Pink = 10" cement footings in sonotubes, dug 4' down, - Red = existing fence - Blue = existing 6x6 fence posts (set in cement footings) - Black = bump out from house http://imageshack.us/photo/my-images/853/deckc.jpg/ My other question is what should i use for joists? Are 2x8's 16" OC okay? should it be 12"? Thanks in advance for your help guys.
