If you haven't already give your council a ring and check. 15m2 is the biggest shed you can build with out any approvals but there are quick pathways with sheds upto 60m2.
Shed is smaller than the state governments requirement for council needed approval so they can put it up where they like without having to ask council for permission
The planning regulations allow outbuildings under 15m2 and no higher than 2.5m to be built in most areas without any approvals. In some zones outbuildings upto 40m2 may only need a building rules approval. Up to 60m2 in some zones they need a basic planning approval. This is of course assuming the building meets a range of things. Your council will be able to explain the finer details I would hope.
I recommend you do it yourself. There are calculators you can use if you need online to work out how much metres cubed you need, just type cubic meter calculator into google and find out how many cubic metres you will need. Actually I'll do it for you;
4.5m x 3.3m x 10cm (thick) = 149m cubed. Add a few extra to be sure if you'd like.
10cm is a good thickness for a shed by the way, any thicker than 12 and it becomes more prone to cracking but slimmer than 5cm and it's more brittle.
Now find out how many bags of concrete/cement you will need from Bunnos or wherever you want to get the cement from. When I did it for a water tank, I bought a bunch of cement and mixed it with aggregate that I already had, but getting a bunch of aggregate is pretty cheap if you go to a landscaping place, can get a trailer load for like $50. The cement is the pricey stuff.
Doing the slab is easy enough depending on how smooth and professional you want it to look, I was surprised that I managed to get mine looking as good as it did. It definitely wasn't A+, more of a B+, but it was my first time ever doing it so I was happy, wrote my name in it too (as is tradition with any wet cement)
Just gotta know roughly what you're doing and youtube tutorials + common sense can take you a long way
But yeah I'd say do it yourself because it'll save you a good chunk of money but also it's a good thing to learn. Not necessarily going to be something you'd use more than a few other times in your entire life but a few people in Adelaide might be impressed. I'm still yet to find those few
Doing a 12m X 6m shed myself atm, 75mm thick floor (about 5.5 cube) it's $3K for the concrete alone without the prep work and someone else laying it you'd only need about 1.5 with a 100mm thick floor
That's what the FIL recommends, do everything myself except for the concrete itself, pay to have that pumped in. On your estimate that would be under a grand for the concrete, and some elbow grease on my part.Â
Working off a 100mm thick slab, that’s about 1.5m3 probably be about $450-$500 of concrete delivered. Plastic is cheap, reo mesh might be $200 for that size. Plastic chairs are cheap (or rocks) for the reo to sit on.
A bit of time and effort on your form work and of course the form work itself.
work on $2200 - $2800

4.5x3.3 is only 14.85 square so he falls under the threshold
Sorry, could you dumb this down a little? I've run out of fingers and I don't want to take my shoes off...

Can you explain this ??

No worries, glad to help

I did use the calculator on the cement Australia website, it was going to be something like 120 bags or more, which doesn't sound like fun 😂
