Low-level decking plan

[Caz11]

Hi there. I've been lurking here for several weeks getting ideas for my deck. Just need an opinion on the plan I've come up with. I haven't draw in the joists. The deck would be 8m by 5.3m attached part way on two sides to the house. I'm thinking bearers 140mm x 45mm doubled up and spaced at 1.6m. With galv stirrups every 1.75m. The ledgers attached to the house would be same size as the bearers. Would my joists be ok at 120mm x 45mm? Or could I get away with smaller?

I only have around 180mm of height so I need to make single level structure with joist hangers. Also area is currently slabbed. Do you recommend taking them up? Or leaving them there? taking them up will get me a little more clearance underneath and perhaps be better if any moisture gets in? The entire deck is under an existing patio, however weather can still blow in. Any thoughts or advice would be appreciated. Thanks.

Looks brilliant @Caz11, very well done.

Thanks so much for coming back and sharing the end result. I'm sure it will inspire others. If you could share more of what you learned along the way, I'm sure other members will appreciate it as low-level decks are always hugely popular and often a tough challenge.

Thanks again,

Jason

Awesome work. Question who did you go through with planning and permits and drawings etc for council approval

Welcome to the Bunnings Workshop community @johnrmonk. It's wonderful to have you join us, and many thanks for your question about this terrific project.

Let me tag @Caz11 to see if they can assist you with your question.

The first step is to speak with your local council to determine whether you need a permit and whether any soil testing is required. If you do, then it would be best to contact an engineer in your local area to put plans together for you.

Please let me know if you have any questions.
