Thank you for encouraging us to start this DIY project. We have done a few DIY projects around the house such as retaining walls and building in some shelves around our fireplace from scratch...while i feel confident in our abilities to be able to complete this project over time, we are after a little guidance to help get started.
What we are aiming to do is build a low lying deck over an existing, rather degraded concrete patio type area and at the same time a smallish deck that wraps part way round our mango tree.
What we would love your assistance with is figuring out:
We've done a bit of trawling of other projects in this community and the interwebs, and due to perhaps needing to access facilities underground at some stage in the future, we are leaning towards building on TuffBlocks or pedestal type builders feet ?
We were thinking that perhaps we would use a composite decking as the mango tree deck will be a little exposed to the elements and the sprinkler, but ultimately it'll come down to cost.

QUESTIONS I have
MANGO TREE DECK - other info you may need to know.
The measurements around the trunk of the tree I'm not confidant are accurate as I wasn't sure the best way to approach that, or the angles out from the 90 degree straight edges? I've attached a photo of the site though - excuse the mess eek but you know, DIY life LOL!
We hadn't installed it at the time I took the photo of the Mango Tree area, but we have popped in a couple of sleepers where the tape measure is in the photo as we want to level out the turfed area behind it and returf.
The idea is that you walk straight off the levelled out turn area and onto the deck, so they should be level to each other if that makes sense?
QUESTIONS I have so many but will start with:
We are super keen to get started ASAP hoping to have this done by christmas so any help you and this community can provide would be unreal and we thank you in advance.
It's great to see that you've drawn up some initial plans for your decks. Let me try and give you some recommendations with your first deck over concrete. Let's do some quick calculations, for example, if you used 70 x 35 framing timber and turned it on its side with the 70mm side facing up. Add the thickness of the Ekodeck which is 23mm you would have a total of 58mm with a 2mm air gap. It is vital to have an air gap between your deck and the ground, 2mm is not enough. Moisture will get trapped under the frame and severely shorten the life of your deck.
I suggest having a look at this guide - How to build a low-level deck by @Adam_W. This will give you the basics of how to make your plan. It's always best practice to have a ledger for the joists to hang on to rather than mounting it directly to the house. I encourage you to try and make a plan and post it here for our members to have a look at. We can then make recommendations based on that plan.
Your decking and framing quantity will be based on the size of the deck you plan on building. Your mango tree decking looks much more promising as it is not attached to your house and there are no height limitations. Using the TuffBlock 300 x 300 x 90mm Instant Foundation System Deck Support should be ideal for your build.

Here are some amazing low-level deck projects our members have shared in Workshop.
Please keep us updated with your progress, we look forward to seeing your decking plans.
If you need further assistance, please let us know.
UPDATE: We have finished the Mango Tree Deck...and couldn't be happier with the result.
Took three days all up to complete. We used EkoDecking.
We now need to get deco delivered so we can finish the footpaths that will lead from deck through the vege patch out the back.
Thank you so much for sharing your construction photos. Your deck framing looks very well supported, I see from your build that you've used DEKO 250 x 150 x 150mm Instant Concrete Foundation Block. Was it easy to use and level or did you level the area first before laying the blocks? Your deck looks wonderful and I'm sure it's a great relaxation spot as it's right under the tree. Are you laying down a footpath? I'm sure our members would be keen to see this next part of your project. Any updates you can provide would be much appreciated.
Again, thank you for sharing your low-level deck project.
Yes it is lovely to relax under the big mango tree :). we feel pretty lucky.
We actually did level the area as best we could before laying down the builders plastic but then had to do some minor adjustments using deco. under the concrete blocks to get the supporting frame more level.
I originally wanted to use tuffblocks being they were lighter weight and also sit a little closer to the ground, but the Bunnings trade people we were dealing with recommended the concrete blocks. They were just awkward to handle and move but all in all okay for this first time deck builder to do on her own. We are planning on a footpath using compacted deco and stones - stay tuned for updates once done
Certainly makes a big change to the area - that's my idea of a deck. Well done!
