Disclaimer: this deck was not built "properly" I decided I wanted a deck, watched some videos on youtube, picked up some materials and built the deck all within 10 hours on a Saturday afternoon.

it's a basic 10x10 deck with pressure treated wood, 12" on center 2x6x10 joists, 1x6x12 boards used for decking, 3" deck screws and a single 4x4x8 post was cut for a few pieces... The brick under the post is not for support, just to keep the wood off the grass, both posts are bolted into the existing retaining wall and 50% of the depth is sitting on top a concrete foundation (with vapour barrier), lastly, 15 feet of the perimeter is bolted to the house so the deck is not going anywhere.

thanks for watching!
