39 inch - 1000mm corner brick WFO build - Newcastle au

[Newie newby]

Hi all,
I have wanted one of these for many years and have finally been able to start building one in the back yard.
I have done a fair bit of research and looked at the forum for other typical builds for ideas.
We have been doing backyard renovations and additions for a few years and I have started to incorporate a corner WFO as part of our landscaping plan.
We did a number of core filled reinforced concrete block retaining walls due to slope in the yard and one of the corner walls looked like a good spot to add in the WFO.
For a typical corner design, I have allowed for approx 2000mm each way in the corners and coming out approx 1000m with new RC block walls to support the new suspended slab hearth.
I got up to the suspended slab stage last September but lots of other reno projects have taken priority for a while.
I have taken a lot of construction pics and will post some on the forum once I resize the pic sizes.
Cheers,
Brad

Here's a sketch of the additional blockwork and footings extended from the existing core filled RC retaining walls

As the existing strip footings extend out a decent distance out from the retaining walls, I just dug out a couple of extra pads, added some reinforcing steel and starter bars for the blocks and concreted the footings to create a good base for the stand.

If you are wondering what the stone blocks are, they were old house piers that were on site that we decided to keep and repurpose into some steps and seating to the new terrace area. They were too heavy for me to lift, I got a guy with a machine to help move these into place a bit later on.

Got our block layer back to lay the extra blocks. Added horizontal and vertical starter bars and core filled with home mixed concrete. Bought an old mixer to make things a bit easier for me on site.

With around 140-150mm deep RC slab (and 190mm plus thickened edge beam to perimeter of stand), top of slab will be just under 1000mm high.
Added lots of dowel bars into existing walls, plus internal perimeter beam screw bolted into blocks.
Sacrificial corrugated iron cladding to base of suspended slab, temporary timber supports under.
Form ply to perimeter as formwork, screw bolted to blockwork.
Went crazy with lots of bottom, top and edge beam steel, with steel and slab thickness I dont think it will fall down any time soon.
Added plastic electrical conduit in centre of slab too as drain hole for any moisture under oven floor.

Didn't realise how long it would take to mix by hand and it was dark by the time I got it in. Could have gotten a better finish on it if I kept going back to it but was getting a bit late and I was over it by this time. Will probably be tiling the slab surface later anyway so all good. Put a bit of fall from back to outsides and also centre slightly higher to reduce water ponding under floor. Will just add some sand under floor to level up later. Beer always tastes nicer when you have done a bit of concreting!

So the slab was poured last September, then worked on some more landscaping and edging to get ready to lay turf to this terrace area.

[Newie newby]

Put down aluminium garden edging, gravel one side and soil and turf the other. got the turf laid just before christmas last year.

Back yard is starting to take shape with new rear covered deck, terraced retaining walls and garden areas, pool and man cave/brewery/boat shed/garage almost finished. Now onto the wood fired oven build....

Bought a precut masonry 1000mm pompeii kit from sydney fire bricks. Looking forward to getting it built.

Mock up of floor fire brick tiles

[Newie newby]

Kit comes with 50mm calsil board for under floor insulation and insulating fire bricks for 1st course, but decided to cast another 90mm thick slab with 5:1 ratio perlite/cement mix under entire oven floor to get a bit more insulation. Made formwork with 90mm treated pine on suspended slab, then marked up around floor and perimeter bricks and cut some 3mm flexible masonite type sheet and formed curve and screwed into place.
