Cost to slide and raise a house in Brisbane

We've been told ballpark (from a house raiser who looked on google earth as they spoke with me on the phone) that our house raise and move over would be about $90k.

That was for everything, new stairs back and front, new posts, hook up of services. The actual slide is probably about $20k to $30k I gather. I know we could save money to getting them to just do the lift and shift. We could hire a builder to quote on the stairs and hire a plumber and electrician to disconnect and hook back up. That is more likely what we will do, depending on quotes.

We could just get a "one company does it all" depending on actual firm quotes but we aren't ready to go ahead yet, so have done nothing more than get ballpark quotes on the phone.

This is off the top of my head, from memory. I have details in another thread, which I could try to find so I can give more accurate figures.

The draftsman who drew up the houses in their new positions, raised up to legal height, drew two sets of plans. One just "as is" but higher and on the new small lot, and the other plan showing new kitchen downstairs, new bathrooms, living rooms downstairs. He said to build under we would be looking around $300k for the whole lift/shift/raise/slab/services/build under.

One option I want to explore is to lift and slide, possibly add internal stairs that are closed off downstairs and either batten in, or weatherboard in the rest of the downstairs footprint, have plumbing set into the new slab but do nothing more. That gives us an option to not overspend when we do it or leave the actual closing in and building internal downstairs walls, bathrooms etc to the next owner.

The problem for us is that spending $300k on the whole thing would give us a house worth considerably more but the extra rent for the extra amenities would not support the cost of providing those amenities.

We have no option but to lift and shift the house, so that is a "must spend". We will get no extra rent for lifting and sliding the house. Everything beyond that must pay for itself.

In your situation, I would suggest clearing the block and starting fresh (building two new houses) would likely cost less than altering the current house and building one new house.

 

Just want to add... please don't make any decisions due to my comments. The particular house I'm dealing with might have its own issues, certainly is not able to be demolished, has its own quirks and the draftsman could have been talking "high spec" at those costs, whilst I know we can do the job for much less if we go "low spec" and/or do the absolute minimum.

We also had a builder quote $300k from memory for a reasonably high spec new build behind this house. It was either $200k for lowest house, and $300k for highest, or something like that. So if you can build two houses for $300k I think you should ignore my comments, as we are likely talking chalk and cheese, either in spec or position, or house quality required for this particular street to fit in with other houses, or degree of difficulty.
