Mine is on the high floor and on stack 10. You can check
www.streetsine.com and look for casa merah. Gives u and indication on the transacted price.
The developer, TID Pte Ltd did not make any official lauches yet, correct me if am wrong. Yes it is for residential site. The commercial plot is still there next to it side by side. You can see the sign board if you drive along the main road.
However, still not sure if is office and retail. Of coz i prefer the latter. Saw the $psf is increasing day by day but it is just a trend, nobody is buying it officially.
