Slopping Terrace Floors

[lenojd]

I have been looking at a small 2 story terrace in Sydney that has slopping floors on both levels. It's a standard 2 story terrace, living downstairs and 2 rooms upstairs.

It has been priced accordingly but I am just trying to get a feel for the work involved in fixing up this problem.

I believe underpinning plus concreting should take care of leveling the ground floor (I hope!)?

Is there anything that can be done about the second floor (2 bedrooms only) sloping?

Thanks!
