The fundamental problem is that this isn't a luxury development, in either its finishes or its design. Your suggestions are all genuine improvements, but none of them would fix the developers' fundamental misunderstanding of what luxury is. Take the wine display. The builder argued on Twitter that AC can keep wines chilled in that open, sunlit living room. That shows no understanding of how wine is stored. UV light spoils wine, which is why it's kept in dark cellars. Wine needs a steady 12–14°C. That large glazed room cooled with an AC, warming up every time the power goes, will slowly cook it flat or jammy, while the dry air from the AC shrinks the corks. It's part of why wines here often taste different from the same label abroad. Beyond that, the workmanship lets it down: the tiling, caulking, millwork, stonework and door installations. The open kitchen and the location of the sink also misreads how an open kitchen actually works when you're hosting. Surprisingly, after all that, I like the architecture. The façade is well executed and would hold its own in Dubai or California. It's undone by poor space and privacy planning, atrocious finishes, and a clear misunderstanding of what luxury truly is. The real tragedy is that the builders will disagree with everything you and I have said.
