A low deck is rather simplistic. Well, it feels that way after building most of a house. A few strategically placed concrete pier blocks, a few extra for supporting the weight of a full tub. Level everything up. 4x6 beams, 2x6 cross whatevers (I don't know the correct name for them), then 2x4 deck planks. Prime everything, two coats of deck paint (did the priming and first coat before the pieces were nailed together)....wallah! Deck. Oops, forgot to make a step in front of the sliding door. No problem. That's easy. Had time to prime the step, but the painting will get done later.
