@mellybean1, Hubby and I have installed an indoor pool into the home we are currently building but fortunately we were able to do everything ourselves, including all the foundations, pool excavation, plumbing and concreting. Could't begin to work out how much you would have to pay to have a pool installed on a slope too and totally by others but I'll give you a bit of an idea of what I know: Engineers plans for pool construction - $3,000 Fibreglass pool - $20,000 Excavation costs including removal of soil with trucks, if you cant use it elsewhere in the build: $10,000 Excavation if you had rocks: $20,000 Foundations a bit of an unknown but a concrete pool about 15m x 3m x 1.5m would include several loads of concrete at approx $1,000 a load and each truck load would hold about 5 mtrs. I'm guessing about 3 loads for the pool alone, however concrete used in pools is differend and sprayed on and not installed like ordinary concrete that can slump, so it's probably allot more than $1,000 a load. Concrete pump to use to construct concrete pool: $2,000 to come to your door before it begins forming up the pool. Pool fencing, a guess $5,000 You won't have much change out of about $80,000 My figures could be a bit wrong but they will be fairly close. Labour nowadays constitutes approx.60-70% of the value of the works to be performed. Best of luck. Cheers, Barbara

Thanks so much for the comments. It’s literally cutting & installing the skirting boards only (no architraves) and we are providing the boards already painted (5.4m lengths). It will be a clear run as it‘ll be right after the new floors are laid so no furniture around at all. Quite a lot of angle cuts though. Still reasonable? I suppose it comes down to peace of mind on a quality job or take a punt on a handyman (unfortunately don’t know any so would have to take a chance). Oh dear, wish the budget wasn’t so tight otherwise I wouldn’t hesitate.

this is a much bigger changes than just a wall and involves foundations, floor and roof as well as plans and Council Development application but the plans imply that you will be making the building smaller which is a very unusual choice but you will need to ask a builder for quotes

No, builder coming around tomorrow for first time, as is Class 2 designer (been a rush to get a bunch of class 2 consultants on board for a simple reno). So far all my own investigations. The slab is structural, 275 thick with localised thickened beams over the posts in the carpark. Opening it up would probably be refused by Strata. I can go look at the original structural details to see how much cover is over the reo - maybe I can get a 20-30mm scabble and do the rest with screed to cover before tiles. It'd be very flat though. Will need a structural engineer to sign off on the detail, and if I'm honest, I'm uncomfortable reducing cover to the reinforcement as below and think it opens up a bunch of risks. I'll run this past them tomorrow for their comment though.
