More info required BTW sketches also help Hi Thanks for the reply. The garage will be at ground level and is purely for the look instead of rendered blockwork or timber. It will be a 6 x 6 garage with a second timber level on top. So fairly straightforward on level ground. I'm trying to get an idea of the Sqm pricing. Cheers Re: Concrete Garage 4May 10, 2018 6:19 pm From my experience concrete finishes look crap unless you opt for architectural off form finish in which case it becomes very costly. Off form concrete finish is used in signature buildings where pockets are deep. It requires meticulous design and detailing and an experienced (commercial) builder to match. You are already asking for price which tells me you can't afford it. Stick to masonry finish or have it rendered and spend your money on more worthwhile wow feature.

Alternatively, you chose the one with insulation and render on top. You should be looking into around $140 per sq m + GST for carpentry labour and blocks themselves + add concrete, reo and pump costs on top. Acrylic render or masonry finish - another $50-60 per sq m + GST. So let's say 6x6 sq m garage walls (2.8 m height) minus opening for 2,4x4.8 garage door will be costing you 2.8x6*4-(2.4*4.8 )*$250=~$14K supply & installed (with one side rendered). If you want to stick to insitu concrete, then you would have to invest into formwork and full structural engineering (for existing ICF blocks it is already pretty much defined, but you would still require certificate).

I think I might just get the block work done around the sides and get some guys to form up and do the concrete. To be honest the cost is not really the issue I am just putting a budget together for a rebuild and am after a defined contemporary look with the concrete and wood. I haven't had the formwork for the walls done before so was unsure of cost per SQM.

Thanks Alex I had been looking into the insulated foam blocks as seen the HomeForm ones in the UK. This is something I need to look into further. Thanks for the reply and info.

Why not use a Lysaght Colorbond Profile internally as part of the formwork That would be a Fantastic Contemporary wall look ie Colorbond internally &, Concrete & Timber externally and I am happy to give you the details...lol, If you promise to put up the photos when completed?
