Just trying to study your floor plans which unfortunately I can't read so can only guess at the room use. I have no idea of the room sizes either, but I'm just wondering if you have actually done furniture layouts for each room to scale. This is really important. It seems to me like you have some great ideas you have picked up but then tried to make the rest of the house fit around them. How many people do you intend having live in the house? You have a lovely generous ensuite with a private toilet area for two people, but then have a main bathroom for how many people, jammed into a space almost half the size of the ensuite. Even the toilet is in there with no privacy whatsoever meaning that entire space can only be used by one person at a time. If you are planning this for kids, that will translate into lots of fights and arguments. If you want to create a really luxe and practical space, create a separate enclosed toilet, the shower and bath in an enclosed space and the vanity open for use at any time. This would be more in keeping with the standard you have set in the ensuite and balance the house so much better. These sort of details have a major impact on the overall value and attractiveness of your home. I don't know what you plan for the open space upstairs, but with a window along one wall a passageway the other side and only minimal wall space your use of this room will be severely restricted. Similarly the room under it will be very limited in its use. All the more reason to plan furniture to scale. I have seen master bedrooms done with the double doors which look very grand in the right sized room but in the wrong sized room, it just looks ridiculously pretentious to fling the doors open with a flourish, take two steps into the room and fall over the end of the bed. I'm sorry if I'm sounding harsh here, just trying to use my years of experience to help you create an amazing house. I've seen many pitfalls and I know how easy they are to make. You obviously intend spending a lot of money and you have some great ideas judging by your Ideas Books. Create more Ideas Books to cover every room of your house, then go talk to an architect, show him/her what you want, your Ideas Books will be invaluable to understand your likes and tastes and let him/her create something unique and special for you.

Oh! Thank you so much. You have no idea how good that makes me feel.😁A Houzz helper suggested this rug on the feral terracotta coloured tiles. I am so scared of colour but I love this rug & am forever in her debt. I thought my husband was going to have a heart attack when I returned from Bowral (we’re in Old Bar-Taree) with that colourful glass bowl on the glass table. At 67 I have finally accepted colour! Lol. Lose the fish tank unless you need it to de-stress, but put it in another room maybe. Any fish we had, died!! Ooh, you have power points too! 😁x Lorraine

after attempting numerous variations i can't see any great advantages to an extra 1800 added on to the living area except to offer extra length and empty floor space to a room that is already big enough for all the basics but lacks wall space for storage and TV but, without a wide opening to the entry, you could have a couch arranged differently and a doorway to bed 3 would reduce storage and furniture options for both bedroom and lounge but, maybe the window in the lounge could be replaced with a cantilevered bay window with awning roof roof to create a bay window seat and the small extension could be better used to add a generous laundry which would allow more storage in the kitchen or a more generous bathroom as the only way i can find to keep a separate toilet is to move the existing toilet door to allow enough space to add a tiny handbasin to the existing toilet plus a door across the entry hall to add privacy from the front door another option for the master suite, would be to steal space off bed 2 to relocate all 3700mm of the original biw and use small freestanding wardrobes and/or chests of drawers for storage in the minor bedrooms...some varaitions for the bathroom and other ideas collected into one plan and you could also keep the original master bedroom for guests and invest in a spacious new master bedroom (with or without an ens) behind the new garage with access through the original bed 2 that could be used as a dressing room and whichever bathroom varaistion you prefer

more bearers is usually better ... economise elsewhere that can be replaced more easily
