the lower section is piers with bearers and joists, because of the lower height 3.7M block was the only real option for strength and 3 car garage also block allows big open plan upstairs with lots of glass and still strong I buy blocks for $209 ea and pay $2.70 for laying, cutting is extra $20 per M The block team gave me a good kick start, 3 weeks to this stage. soon it will just be me and another chippy slogging it out.
