Hi evreryone
We are about to build a duplex in Sydney and haven't decided whether i am going to put a slab down or bearers and joists. Does anyone here have experience with this there is about a 1 meter fall on the building foundation. We really wanted to lay floorboards inside so that's why im thinking its cheaper for bearers and joists otherwise we have to batten teh slab.
Any opinions would be greatful
Thanks
On a flat site, slab on ground is easier and generally faster to build. Slab on ground is rarely ever cheaper.
In the case of having to decide between cut and fill, retaining walls and deep beam footings for a slab on fill compared with pier and beam/bearers and joists – it should be much cheaper in constructing a timber floor in much the traditional way. As you have over a metre of fall, there should be no problems in achieving underfloor access or providing subfloor ventilation. Nor will you have to lay a second floor to get your timber flooring.

g,day here in s,a,theres a bit more to think about than just the cost,it,s about based on the soil type and the enginers calculations concrete floors are economical only on flat sites up to 300mm fall with 1m fall if you cut and fill you have piers and retaining walls to add to the cost, with a raised floor you may gain better views, alternative materials as steel sub frame,etc or a waffle pod slab cold be an alternative to look at with a floating timber floor on the top,,,good luck from garry
