Look at Sydney Mixed Blue Gum or Tallowwood perhaps. A hardwood floor will look awesome no matter what species is chosen, you can't really go wrong.

The exterior transformation is wonderful. Not too sure about the internal colour scheme selected. I much prefer neutral tones. A matter of taste I suppose.

I must be getting really old - it is interesting where technology is taking us but there is nothing there that I could not live without.

Appreciated am coming in late to this conversation, but generally the ideas are there, but I'd be playing with it a bit more.......there are 2 big ones for me here. Firstly missing the opportunity with the master suite. The whole thing should arguably be flipped so the bedroom space is to the rear/outlook to the pool and the bathroom/robe amenity internalised. If you're going that far with extension works arguably a bit of structure/engineering implemented to support the upper level is worth the investment to get the layout working. Design decisions should always be driven from the experience of the space. and 2. Not that convinced about the flow from entry to main living through an internalised dining space. Its like the kitchen/living/dining relationship is similarly not functionally balanced,. It's like the dining should be aligned with the kitchen space and living then separated....How exactly is that living space intended to be furnished?? At this design stage furniture should always be on the plan. You have to design from the inside out, make it work functionally and then deal with the walls/windows/doors etc last What's you're budget? Has your design given you projected costings on this? You want to make sure you don't need up with a conservative design solution that ends up costing you more than you wanted, and you then spend the money anyway but miss the opportunity for a much better resolved, higher value option than makes sense spatially for the way the house will be used and experienced. Best of luck PD :) www.pauldistefanodesign.com
