That is not the case in Perth raft footings, slab on ground and double brick is the norm The cost of housing in Sydney is significantly more than Perth, but that has a lot to do with conditioning, what you are expected to pay, herd acceptance, etc, etc . Always question the data and reports, then make up your own mind.

I thought that they don't make wafflepod slabs at all in some cities where there are strong winds and in cyclone-prone areas. Well to my understanding, Perth is considered to be a windy region. But then, winds can be high in Sydney and Melbourne too. I guess you're right, builders mostly follow norms (of conventional slabs and double brick construction). I think I'll have to dig in more knowledge. I tried to ask few people on fb pages in perth, they don't know about WP at all, which was kinda surprising to me. Re: Slab selection 6Jan 22, 2021 3:01 pm We use raft on a sand bed at $25m3 why would you bother with polystyrene void formers at $50m3 in perth? OT If you were to build a Std Perth house, ie, Slab, Double Brick, pitched stick roof house in Sydney it would be twice the price.and over Engineered for what you get by comparison. Steer clear of unorthodox construction methodologies, the Trade/Builders always find ways to gouge more in variation costs Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: Slab selection 7Jan 25, 2021 8:30 am StructuralBIMGuy We use raft on a sand bed at $25m3 why would you bother with polystyrene void formers at $50m3 in perth?

Steer clear of unorthodox construction methodologies, the Trade/Builders always find ways to gouge more in variation costs True, I was thinking of going with icf construction method, which is why I thought i should go with WP slabs. But if WP cost $50/m3 compared to $25/m3, then it would be useful to think of WP. I read on different forums and webpages that WP costs cheaper cus it uses lesser concrete and less digging but then the polysterne have costs too. So I'll have to compare between these 2 first.

It's not clear here actually Re: Slab selection 11Jan 25, 2021 6:19 pm Rafay - your best bet is to get local quotes for waffle slabs and raft slabs as a m2 rate, and see what the differences are. Building is not difficult at all once you understand the process - what will make or break you is your tradespeople. Pay extra, and get quality trades, and that will make up for what you lack.
