Ok so I have plans to build a deck in my back yard, roughly 30 square metres or a bit over 300 square feet. I'm in Australia, hence non-freedom units.
Here is a mockup of the planned deck, using good ol' Excel.
The deck will roughly be 6 metres by 5 metres. There's wall on three sides, as shown by the darker red. The grey square is a concrete on which the water heater sits. The lighter red is where a door and a sliding door is.
The house is brick veneer so I'm making the deck freestanding rather than attaching it.
Each square represents 100 millimeters by 10 millimeters, aka 100 square cm aka 15.5 square inches.
Black squares represent the deck posts, measuring 100mm by 100mm. These will be sitting on concrete supports going down about a foot.
Yellow represents the bearers aka beams, which will be 140mm by 45mm and as long as necessary. Note that they sit either side of the post.
Green represents joists, which will also be 140mm by 45mm.
Here is a link to the span guide I used when planning it.
Important note: I am putting the joists between the bearers rather than laying them across the top of the bearers. This is because I'm a bit limited for space, vertically-speaking. I've dug out the area of the deck about a foot, and I would like to keep a few inches gap between the bearers and the ground. So this means joists between bearers.
I've installed drainage already, so pooling water shouldn't be a problem.
Which brings me to my next problem: note that on the middle bearer, on the left hand side, there's no post drawn in. This is because there's a bit too much going on in that area re: drainage pipes, so I've left the post out. Can I get away with not putting in a post there? Consider how close the other bearers are, will they be able to bear the weight? The other alternative is that I just sit a concrete footer on the ground, rather than in the ground, and put the post on that.
Also note how close some of the posts are to the house. Is it ok to have them this close? I know it's going to be a pain digging them when they're that close, but that's my problem.
Any thoughts? Comments? Ridicule?
