Hi.
We have signed and paid deposit for a company to build a granny flat (60m2) in our backyard.
After 9 months of waiting, the council has finally approved our DA.
It turns out that our home is in a flood affected area and hence we had to pay for a flood report and additional building cost to have the granny flat elevated. The additional costs are approximately:
Concrete/slab work for the suspended slab = $17,000
Stair case to be added to the granny flat as per elevations = $4,000
Hand rails = $1,300
Additional bricklaying works for the suspension = $10,000
Any builders on Ozbargain who can comment on the above additional cost?
Do they seems reasonable?
Unfortunately, this blows our budget out the door, but don't think that we have much of a choice.
Thank you.
I would consider getting a quote for timber floor on posts instead of suspended concrete.
