For any of you here who like to virtually browse houses, here is a site that lists some houses for sale in the area where OP lives.

I learned a lot by looking through some of the listings and reading the descriptions:
Some things I learned:
Some houses offer a "pajama lounge" - which I think is the room outside of the master bedroom in OP's house they have been calling a "casual lounge". It is upstairs, near to but separate from the master bedroom in each house where I have seen it.
In the really expensive houses, the kitchen does not have a full sized kitchen sink, just a smallish one. Not as small as a bar sink, but smaller than a regular sink. Apparently there is another room called a "scullery" where you wash dishes. (Sounds a little inconvenient to me, because I use my double sinks a lot when I cook)
Lots and lots of highly contemporary architecture. Lots and lots of huge expanses of ceramic tile. And those metal staircase railings like in OPs house.
I was looking to see if the houses had screens, actually. I do not think I see them. There are plenty of pics of open sliding doors. No screens. Also some do not have a/c because you see fans.
Many of these houses look very sparse inside - like Op's looks to me. Almost unlived in. But they have furniture. I don't know if they have been "staged" for photos or what.
Very much into having things "line up", chairs all in a row. Table cloths on many of the tables.
Always interesting to see what things are like in a different country.
