    I'm about to order the timber and fixings for a raised deck base (approx 900mm off ground) and wondered if anyone could confirm/comment on planned fixings as noted below please ?

    Rim 150 x 47
    Joists 150 x 47 at 400mm centres
    Posts 100 x 100 at 1,250mm centres
    Middle of the 2.6m - double joists lengthways on posts to support middle of 2.5m joists

    I haven't yet worked out how to attach the end rim joists to the ledger as I haven't been able to source concealed joist hangers anywhere ?
