    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 ?

    Raised deck 4.8m x 2.6m with ledger along one of the 4.8m sides
    Ledger 150 x 47
    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

    Ledger to wall

    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 ?

    Apologies for the detail - any comments gratefully received - thanks

    Hi, I'm building a deck with almost the exact same spec. How did you get on with your fixings? I'm at fixing information overload.
