    Hey guys

    Just looking for a little advice on a plan to deck 2 small area's of my garden


    The pic above shows the 2 slabbed patio areas we want to deck

    Top Deck - 2.3m x 2m
    Bottom Deck - 5m x 2.7m

    Her indoors wants straight running deck (not Heron Bone or angled)so that make life a bit easier

    What I am thinking of doing is making a simple 1-2" High Support (Anchored to the concrete slabs)

    My questions (So far) are

    1) Should I lay the wooden support platform directly onto the existing slabs or should I raise it slightly (using evenly spaced out slabs) to keep it off the ground and away from direct contact with laying rain water ?

    2) Should the deck be slightly angled away from the house to allow rain water to run off ?

    3) Also is there any rule of thumb on how many cross supports (Noggins) required ?

    Thanks in advance

    Also, I am right in thinking that I will need to install a ledger board

    1:- yes raise it. use wodden legs then you can get the frame at the level you want

    2: a slight incline will help

    3:- just whats needed to stop the deck moving. we normally use a cross bearer running under the joists and fix them to that. a lot quicker and easier than seperate noggins
