I really dont see this as a trend. I see this as developer exploiting the lack of clarifications and guidelines from the authorities and
numerous loopholes while taking advantage of the hot market. (facilities, carparks, plot ratios, disbursement schedules, construction duration,
commercial/retail guidelines, management and security is not clear also)

there will be genuine interest in these development but to me most will be used for residentials / storage place / office.
why not build service apts (this is bs also, msian service apts), or condos, or offices. why so many SOxx ??? just to squeeze xtra drops of profits of coz.
