Regarding the undermounted sink. How does your family work in the kitchen? Do you have items that need washing, but do not go in the dishwasher? If so, then with no drainer next to the sink, you would have to purchase a microfibre drying mat, to put on your bench top, to protect it from water marks from hand washed items. And why just one sink? Where would you pour, for example, pasta water if the sink already has water in it? In my opinion, a double bowl sink is a better practical solution. I suppose you could put a small bowl in the sink, so this leaves the waste drain free. The under mount sink has the edges of the bench top exposed, therefore care would be needed, as always, as to not chip the bench top when washing big heavy items.

Looks good but need basin in powder room. That is a must

pending more information ..using similar original floorplan with internal stairs but suggest that the alfresco, vernadahs kitchen, halls and living areas could have raked ceilings with the rest of upstairs with flat lower ceilings instead of 3m ceilings throughout upstairs

alternative ideas

Yes it is quite a unique block which our ‘designers’ struggled with.
The main view is south facing hence the wider deck. It gets really hot here so this will be a haven.
We put the clerestory’s in to try to access more natural light however our building codes here have strict regulations on window to floor ratio for thermal capacity. We also have bushfire codes to abide by.
The next best view is the east hence main bedroom and extra seating on verandah.
Just the two of us so we made the guest bedrooms smaller ??

thanks dreamer..finally think i understand the correct orientation so another variation to consider...inside rooms about 150sqm plus balconies and alfresco (total site area about 20m x 14m) with gable roof towards south and north facing hip roof allows about 50sqm of north facing roof for solar panels with extra undercover space for solar battery, water pump. AC and water heater ...raked ceilings over alfresco, balconies, kitchen, dining and living area with flat ceilings in the rest of the house for easier insulation and use smaller sliding glass doors and louvre windows for better ventilation, open mesh shelves in storage and wardrobes to minimise dampness and mould in tropics and add adjustable sarlon shade cloth blinds and/or external rollwer shutters for extra sunshade and fire protection

Great good cross ventilation. No wasted space.

Your dome lamp is still very popular, adding pieces to compliment it will draw the room together.

The first thing that jumps out at me is that the picture is hung too high. The design rule for hanging art above a sideboard or console is the bottom should be no more than 15 to 20cm above it. Look at examples in Julie's pics. At the moment it looks like its floating and not connected.

Chat gpt does wonders

Table and chairs match. Could get chairs reupholstered. Rug should extend out beyond chairs so you can sit and pull chair in without it getting caught on rug edge.

Agree with bigreader. Don’t add a floor rug. Remove the current centre piece, it is out of proportion. Find a textured table runner which is long enough to hang over the end of the table. Add a simple small centrepiece for the table. You could purchase chair covers from IKEA, Temu, Etsy. Or get them reupholstered. The curtains could do with replacing as well.

Def don’t have half wall upstairs. Need to separate noise sources and kids throwing things over. My sister hated this at her place.

In my opinion a fully tiled bathroom is always the easiest to clean (as long as its not tiny tiles with lots of grout!) but its not always an option financially. The wipeable paints these days are so much better than paints from a few years ago. Do need to make sure there is adequate strong extraction as well.
