Hello everyone,
I'm trying to build a deck in our alfresco. At this point, it's still on the planning stage. I've seen a few posts here and there on this forum and would very much appreciate some further inputs to more experienced people than me.
My background: I work in the IT industry and "hardware" isn't really my thing lol. Anyway, I've built a few benches, and tables (nothing fancy) but not really built anything as big as an outdoor deck.
Project Alfresco: We have a small alfresco that my wife insists should have a deck. I agree, and I want to build it myself. Here's some bit of a challenge. The brick height is low, and also, "not even" from the side near the wall (corner of the doorway), it's around 130mm slopes down to 125mm the other side. Also, what would look good:(1) building the deck only on the slab of the alfresco, or (2) including the one outside as well?
Need suggestions on best way to build it, should I use this? https://www.bunnings.com.au/tuffblock-300-x-300-x-90mm-instant-foundation-system-deck-support_p24103... shour I do something else? Open to any suggestions at this point since this is my first build.
thank you.
So, in this case, @yeahboo, I'd just make the deck a perfect rectangle working off the largest width. On the smaller end, the deck will overhang the edge of the concrete 3cm, but that won't be seen underneath it.

That would be correct, @yeahboo.
So, you'll create a frame for the deck structure and then fix the joists within it. You'll screw through the frame into the ends of the joists. The feet can then be placed under the joists instead of under the frame as they are connected. That allows you to set the feet in from the wall and the deck's perimeter.
Unless there is a need to connect the frame to the wall, I would try to avoid that, as it adds another layer of complexity. There's no issue creating a floating deck entirely supported by the pedestal feet.

Hi @yeahboo,
With either the 90 or 140mm boards you'll want at least a 5mm gap between them. The choice between them comes down to personal preference. Do you like the look of the wider or thinner board?
Neither the 90 or 140mm board must be pre-oiled before installation. Typically, the boards would be laid and then oiled.
In set lengths, you'd need to go with the 5700mm Merbau decking boards to cover your 4220mm in one board.

Evening @yeahboo
Man I can feel your excitement and must say I am a little bit envious 
Sounds like it will be a great looking deck.
To answer your question, Id build the frame first and then level the lot, at leats the outside edges. I have not used those pedestals before but think they will work the same way the feet do for kitchen cupbooards (they are infinently adjustable)
Id get it level with the pedestals and then bolt the brackets in, the pedestals will do all the hard work of holding ot level while you drill.
Looking forward to the project pics

Hi @yeahboo,
Have a look at this guide: How to build a deck. As @Dave-1 mentioned, I'd build your frame first on the ground, as it will be easiest, and then pop the adjustable feet/brackets under it. I'd cut several 59mm high blocks of timber and use them as temporary chocks under your frame whilst you install the brackets and feet.
Keep us updated!
Mitchell
