Would you be able to assist in the best design for the following? At the moment to section closest to the door rebate only has roughly 150mm of ground clearance (dirt base) and then this slopes to 300mm near the brick pier footings. Thinking of 140x45 treated pine bearers and joist with 90x19mm Merbau decking boards but this already exceeds the 150mm. Ideas and designs are welcome.
Welcome to the Bunnings Workshop community. It's wonderful to have you join us, and thank you for sharing your question about your low-level deck.
Before you begin, I suggest having a look at this guide - How to build a low-level deck by @Adam_W. This will give you the basic steps you'll need to plan your deck. In this particular scenario, since you only have a starting space of 150mm, you'll have to use 90 x 45 framing timber instead. If you add the decking panel thickness of 19mm you'll have a total of 109mm, the remaining gap will be 41mm. This is on the condition that you will build it as a single-layered structure.
I suggest having a look at the Builders Edge Pedestal Feet System in conjunction with pavers and concrete to support your decking frame. But you also have the option of using timber or concrete posts.
I recommend grabbing pen and paper and drawing your idea of how the frame should be laid out. One of the things to keep in mind while planning your decking frame is in which direction are the decking panels going to be laid out? Naturally, the frame will be in the opposite direction as the decking panel.
One of the most important things to keep in mind is water drainage. The last thing you want to happen is for water to sit under your deck. The heavy moisture will damage and shorten the life of your deck. So make sure that there are no low slopes or pits in the area and that you have adequate drainage planned out.
I'm sure my colleague @MitchellMc will be giving you more advice and information for your low-level deck when he returns on Friday.
