The space looks a bit cold & clinical at the moment. Add sheer curtains to the window from ceiling to floor this wall Add some drama and also help to soften the look. I don't think the corrugated iron works use timber instead . A rug will better define the space perhaps with pops of colour like yellow , orange or red this will add some warmth. Prints on the wall , large pot plants side tables and floor lamps . In the billiard area it would look good to add a pendant lamp over the table you can buy ones specifically for billiard tables . More pops of colour also a couple of occasional chairs . You could also add more timber here to give more ambiance. Happy decorating .

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.

Further questions, I've some questions that I'd like to seek opinions from all. Blue shaded = Windows/Glass sliding door Red shaded = Wall Currently, my wife and myself are thinking if we should have walls that are all windows and glass sliding doors as per this image below. Obviously the con is that we can't have any furniture or tv cabinet there but that after researching Pinterest, it seems that all beautiful homes these days have these "glass-enclose" feel. Not sure if it's practical but it definitely looks nice. Another option that we're thinking is to have piece of wall that we can place the tv cabinet (if we want to) or any other furniture/shelves in the future What are the pros/cons? I'm thinking of having the wall there because at least it's "future proof" if we don't want to have a TV there, it can be functional and we can have shelves etc. If we want to have a TV cabinet we can. But my wife thinks having everything enclosed in glass/window/sliding door are nicer and the living area shouldn't need to have a TV since we already have a leisure TV area at the upstairs. Thanks, Venn.
