Hi Yes it can be done and we have done it many times. The only question is how to transfer the dead and live loads... which an engineer will do. (dead load is static weight eg slab/roof etc... live load is people, movable items etc) First step is to dig out the original plans with particular emphasis on the structural plans that show the reinforcement of the second floor slab, footing details and wall sections etc. If you don't have them, you can go to your local Council and request a copy of all plans on file. It will cost around $50-$100. Depending on how the slab was reinforced, you will most likely need a beam to span from the laundry to a point in the other bathroom wall that is remaining. The beam can be designed to be part of a bulkhead or feature dropped ceiling. Then there will probably be some thickening of the wall structure and increase of footing capacity. Footings can be extended by drilling through the slab and grout injection into the soil underneath or excavating and installing new concrete. As others have said, a structural engineer will look at the plans, work out a design and detail that a builder will implement for you within your desired layout. Cheers

How do I fix this problem two primer coats and two dulux aqua enamel. I know I left the tape on too long.

Purchase one of these blade scrapers. After wetting the window frames, try a small area and see if that works. It will be a time consuming job, but very fulfilling.

Use a flat slim tool to get under the strip and pull it up. You will not need that for your planks. You would get a transition strip that is the same colour as your planks, and the transition strip will probably be flat not curved because the planks will change the level of the cement floor. https://flooringonline.com/products/transition-floor-z-trim-grey-oak?variant=19966937825409&gclid=EAIaIQobChMIttPlmN_M-gIVRYNLBR3pMApEEAQYDiABEgJ_pPD_BwE
