For those in Casa Merah stacks directly facing Optima too bad. You will get to peep into your next door new neighbour block. Moreover, Optima is 14 storey, thus may tower over CM which is 12 storey ==> maybe less windy next time but u it willdefinitely absorb all the MRT noise.
Luckily my stack is safe from the Optima stack and view not block.
When construction start, there is definitely an opportunity cost to pay
i.e when Optima or the shopping mall is erected. Need to bear with the piling sound, dust, lorries moving in and out etc. But anyway, construction work is done during the day when most of us are at work,so dun bother lah, at night still come back to your cosy home to relax & koon
On the bright side, when the shopping mall is up, we will be the envy of most of the other East side condo owners , also your condo price will appreciate further when shopping mall is up
