Sorry to continue....the plan by Louise on the 20/01/2017.... But the laundry ( with internal access or through cloak room) and ensuite to the rear of the garage the master behind...... Then a Wir separating the master form the living or a bathroom...... The a fireplace if required against the western wall central in the house.... The entrance and small cloak room for the winter woollies against the garage and the other three beds at the front RHS with bath near.... The lounge/ kitchen/ dining in a similar layout but with minimal a walls blocking the view from the entry to the living/kitchen .... I like at lease a small wall dividing the living and lounge for the teenagers also.... If I get an chance I will sketch something up. Good luck this the paperwork... Plans are the fun part.

Not sure how it comes up in vinyl planks but i chose spotted gum ( Quickstep Readyflor) and am thrilled with the look. The large range of colours through the floors means it suits a range of timbers and furnishing colours. Good luck with your choosing

Council will need to approve it and they then take responsibility for it as it is not on your land.

From a "passive solar design" point of view, everything is right. Rectangular home facing north/south. With north facing living rooms, rarely used rooms to the west. But one other thing to consider, plumbing. Locating it close together will lower building costs, & the wastage of water, waiting for hot water. So I'd consider swapping bedroom 4 for the western wet areas. Behind the kitchen is have the laundry, then bathroom, then linen, the bedroom furthest to the west. I'm not mad about western bedrooms, especially in hot climates. But in this case it sounds like it would be used sparingly. Plus if make sure there was no western window, just a northern one. Insulating the western wall well, & using a radiant barrier (reflective insulation). The approach will also significantly shorten the length of the western hallway. Greatly increasing the size of bedroom 4. Talking room sizes, & room numbers, from a sustainability point of view, I think the home is too large for what is likely to be a two person home for much of the time. The embodied energy (emissions created) from a new build home is huge, averaging 15 years of operational energy. I'd be looking to reduce the house size, by using multipurpose rooms. The occasional kids housed in the study, or the media room. This can work out great with clever design (like incorporating murphy beds). How will the media room be used? Will noise be an issue. Will you be happy to have it so close to the master bed? The building orientation/shape will be great for solar PV, with a large roof area facing north. I'd I was building nowadays, is be aiming for an all-electric home. Ditching gas - of its even available where you are - in favour of efficient electric appliances. Reverse cycle AC for heating (if it's required), supplemented by fans for cooling, hot water heat pump (extremely efficient), induction cooktop (sensitive, fast acting, easy to clean). All powered by solar PV. If it's an option, I'd look at 3 phase power, which will let you install a larger PV system. It will also allow you install a fast charger for EV, likely to be your next car purchase, or soon after.
