If moving plumbing, etc is too much for your budget, why don't you leave existing kitchen where it is, open up the wall to the hallway and that bedroom that faces into the pool area. Close off a wall near the entrance/formal living room to replace the bedroom. Advantages are a) not moving expensive kitchen wiring, plumbing etc. Kitchen window still looks out into entrance to see comings and goings AND back to pool for informal living (maybe casual dining at an island seating area, casual sitting for pool). b) the existing dining, living room is a separate space (great when your kids are older to have two living options for noise isolation - adults in one, kids in the other). Both sets of rooms open off the entrance way, and that new bedroom can be the one you use as home office or guest (leaving other bedrooms for family).

I suppose it all depends on the size of your household, how busy the bathrooms are during the morning rush, how old the kids are, and how much you want to spend on bathroom fitouts. From your plans you are looking at four bathrooms in a four bedroom house, which to many people may seem excessive (and expensive). Downstairs you have a bathroom, probably for visitors use, and for day-to day use. Does the downstairs bathroom have a bath, shower, vanity and toilet? Upstairs you have a new ensuite which looks a good size, with shower, toilet and vanity. Then there is the new family bathroom, which looks smaller than the ensuite, with shower, toilet and vanity. If I had a young family with toddlers I would possibly enlarge this bathroom to include a 1500mm long bath, but with older kids this isn't really necessary. Possibly consider balancing the size of the these two bathrooms so that they are the same size by moving the dividing wall. Both these bathrooms have semi-recessed basins which many people don't like. You have the room for full depth vanity, which gives you more options when selecting your vanity basin and tapware, as well as more benchspace. Then there is the older, upstairs bathroom, which you are keeping the same, with the laundry chute, possibly to save money on a new bathroom fit out? If this older bathroom already has a toilet and vanity you probably don't need an additional powder room upstairs. There is no issue with having an ensuite and family bathroom back to back, and it makes sense as far as plumbing, and sharing sewer stacks etc. Have you discussed with your draftsperson how these will be concealed from the downstairs rooms?

Fibro is short for fibro asbestos. This means that the fibro cladding contains asbestos. You cannot work with asbestos due to the health risks. You can't drill into it, cut it, or remove it yourselves. If you are considering buying a fibro asbestos house then you should factor in getting all of the asbestos removed before you renovate, and this work can only be done by a licensed and certified asbestos removal specialist, which is expensive. You then have the cost of recladding it in a new material. https://asbestosawareness.com.au/asbestos-in-the-home/home-renovations-diy-asbestos/ Many fibro asbestos homes are very cheap on the market as the renovation options are limited unless you spend lots of money in asbestos removal. I would suggest you get a quote from a local asbestos remover before getting your hopes up on this property. Your renovation dollar will go a lot further with a non-fibro asbestos home.

The knots look like pine to me. Is that raw timber or does it have a coating? A trip with the pic to the timber shop would be a good bet.
