Kind of funny really how many people would feel exposed and would not want to use the bathroom. The more I think about it, it's a bit like a public restroom with stalls (as stall walls rarely go to the ceiling or floor and have the added issues of gaps between the wall panels and doors -- which thankfully we won't have!). Regarding the humidity control issue, I should have clarified this is only for a toilet and small hand basin (not a full bathroom with shower). The main room on the other side of the proposed toilet is our dog whelping room where we will have young litters of puppies (when we have them). Further down the hall, removed from this room, is our training room where there are likely to be other visitors but the proposed bathroom would be quite removed from that area. It would be wonderful to find more windows like the ones that are up near the ceiling! That would certainly solve the issue. I'll have to scour the demolition/restoration places.

We are a little biased, but wood floors are versatile, durable, clean, and timeless. Whereas carpet will eventually need to be replaced, high quality wood floors can last forever. You can install radiant heat under the wood floors if you are worried about them being too cold during certain times of year, and you can easily install area rugs over the flooring. Wood flooring is also more versatile than it has ever been so you can create any look. As an added bonus you can easily sweep and mop your wood floors, whereas with Carpet you don't always know what is lying below the surface. Good luck!

Is this a new build? I would suggest you look at each room in detail and put the actual furniture arrangement you will have, to the right scale, and think about how you will move through and use those spaces. Some of those look odd to me, but it may be the way you intend to use those spaces is different to my imagination. The access to the changing room seems only through the Kitchen. and either out the front door or dining and living to get to the pool area. How will this be fenced? Where is washing to be carried from the laundry? Is there a line nearby? Out the front door, or through kitchen dining and living? Bed 4 has to go through a living space to a bathroom, the living room is hard to imagine in use as arranged, and bed 2 and 3 look to have the beds right into a corner for no reason. How would you accommodate a double bed in these rooms? In a few years this may be what you want. If you will have other furniture, draw it in. There a large walk in cupboard/robe off a store room. What will be in the storage room? Draw that in too, so you know there is space and it won't block access to the robe. Many of the storage spaces/benches/shelves are shown with corner shelving arrangements which isn't often the best use of space. Bed 1 looks out onto the front access. How will you provide privacy? What different uses do you imagine in the living, family and rumpus rooms?

A very simple layout keeping the floor space within the kitchen, the WIP takes up a lot of space with not much gain, The broom cupboard could be moved to the Laundry/entrance, narrow. If the wall has been bumped out to the eaves on the deck side giving an extra 300 depth to the kitchen you could make the island 2700 x 1200 and all drawers. The wall of narrow pantry will hold all pantry needs and more, no deep cupboards to dig into. cheers
