Deck Frame : Posts and Noiggins

[SuperAverage]

Hi All,

Im in the process of building a large-ish multi level deck and need some help confirming my plans for the framework.

To be specific its a quesion of having enough support for the frame via posts (legs) and noggins. I have attached an image of the plan and the mock up of the final deck, how am I looking?

I am using 6 x 2 for all the joist work and plan on 400mm (can I get away with 450mm?) centres between joists. I intend to float the whole thing on legs as I am decking over a large concrete area where two garages used to be. This concrete area is mulitlevel already and am essentially using it as a base for the raised areas, nothing will be greater than 10cm off the ground. The deck boards will be 140mm x 40mm cedar.

Any help would be great.

Many Thanks!

Looks good to me - would say more legs though . Cut them to aprox. length and soak the bottom ends that will be on the concrete in wood preserver for days, then put a small piece of plastic damp course under each one onto concrete. You can't overdo the number of legs . as to noggins put them @ the bottom of the joists because your decking will hold the top of the joists. 400 spacing is good for strength- but make sure you're not too tight to get your powerdriver and screws in between when youre fixing the frame . Then coat the lot with a good solvent based waxy type wood stain . You might need special screws for the cedar decking maybe stainless- not sure. perhaps ask in the woodwork forum . That's the way I did my decking frame - then I covered it with plastic "wood" decking
