    Well put it this way, our actual floor they're doing 2m spans with 4 by 2s. So the spans are OK.
    My comments for an amateur point of view would be watch the main beams as they are supporting the ends of quite a few joists, also mind how you hang the main beams onto the posts, I'm sure you can get hangers you can nail in. Don't just screw them in the side.
    Also I assume the deck is near ground level!
    Good luck and let us know how it goes!

    Thanks for the reply, I was planning to attach the main beams to the posts with carriage bolts, and then screw the joists to the main beams, would I be better using joist hangers instead?

    The deck is only a few cm's above the ground, I was thinking of cementing in paving slabs as the ground is compacted hard core and resting the joists on those, but looking through the forums everyone suggests to use posts. Do you think slabs would be better?

    Personally I'd use hangars, but wait for other opinions before you go to any expense. With the base I think as long as you have a big enough bearing and a damp proof layer you should be OK.

    Masonry beats timber everytime so use paving slabs if you can. Posts are more popular because it makes it very adjustable and quick to put up and level.

    Hangers are overkill for me. I use 6/8" timberlok type screws for both joists to ledger and joists onto posts.

    Ah great, thanks for the info, when screwing the joists to the ledger, do you put the screws in at a 45 degree angle?

    Yes i Skew them in. You need to use big strong screws for the job though.

    Basic rule is: lay the deck as designed, and if it bounces, add more supports.
