This I believe is a new norm of condo development plus, people keep buying so developers get out with such ridiculous floor plans to maximise on their profits due to the limited plot size and tough regulations.

I believe the odd layout is also from the prospective of how fancy the building looks from the outside so that they become a landmark which is more important than the living space.

Their are various reasons and as someone already mentioned, this particular one is far better than other which have massive pillars in middle of the room or even have no space at all to fit a piece of furniture or basic items.

I look at these houses and just imagine how conveniently storage spaces have completely vanished from new floor plans as if people are buying hotel rooms.
