We're Owner building an extension and preparing for our knock through to the existing house. Our 1950's Adelaide home has a bathroom/toilet/laundry section that runs across the back of the house (approx 6m x 2m) and our plan from the start has been to get the terrazzo floors broken up and removed so we can extend our timber floors through this area as we have rebuilt these wet areas in the extension and are converting the space to walkways. It was originally suggested to us that the original footings from the house would run through this section and when the terrazzo is removed we can use these footings for our floorboards. We had someone out to quote tonight on the job and he has said that he has never seen footings under terrazzo and we should expect to just find a whole load of dirt and rubble. We hadn't budgeted to totally redo these footings and are now wondering if we should remove it at all.
It'd be great to hear from anyone who has come across this before and if anyone has a suggestion of the most budget friendly way to get around this. We could consider leaving the base as is and tiling over the top but it really won't look right particularly in the laundry that will now become extra space for our timber floored kitchen
I'm not sure how thick terrazzo usually is - would there be any chance of grinding the level down a little to lay overlay timber flooring?
