we start in 13 days, its all happening.
Your prices seem a lot cheaper than I have obtained, I will outline below:
So, for a 3BR on stumps with flat block he estimated:(we are at about $5k for all this)
-$7,000 Architect/drafty/engineer|council approvals|certifier
-$22-25,000 Lift|stumps|steel bearers(we got 6 quotes, went with a quote for about $29.5k, we had 55 concrete posts, reducing to about 43 steel posts, with a 3.5 metre slide, 1.5 metre raise. highest price was $43k, two at about $38k, 3 at $29k)
-$1,000 Site cleanup (removing old cement stumps etc)(haven't factored this yet)
-$7,000 Plumbing in slab & reconnetion of lifted fittings(we are at $10.5k for new sewerage, temp reconnect, and connection of all new services and upstairs services, 2 bath 1 kitchen downstairs, 2 bath 1 kitchen upstairs, not including excavation)
-$13,000 new slab (based on 130m2)(we are at about $8500 here on the same size not including excavation, although my concreter is MIA for the last week or so, stay tuned)
-$3,000 electrical box relocation(friend doing this, dont have budget but sounds right)
-$1,000 Temporary stairs
(ladders are free!)
so we spent last weekend stripping downstairs, as we had a garage, laundry and bathroom downstairs, a few sledges, some pizza and a few mates had it doen in 5 hours, ready for raise.
We have 5 loads of soil sitting in the front yard, we are raising the block 600mm so we need soil to achieve this (to level the block)
as I said, its all happening, a fwe more things to do before we start, but are on schedule.
