I’m the resident here more than 3 month. I convert the studio unit become a bed room.
We have a kids, also sleep together in a room.
Act planing to renovate become 2 room but due to some problem, decline the design.
I’m happy to stay at this 450sf unit, btw let me explain a bit.
My working hour 8am-5pm, normally leave home at 6.30am(sending my son to school) then after work reach home ady 7pm. So normally I stay at this home from 7pm to 6.30am next day. It is 11h30m stay at my home. I satisfy this size because I’m the one to cleaning. 
Why I need a large house if I always not at home?
Almost every weekend and holiday also went out for shopping la, to exercise la and so on..
