Pine Grove will be a much nicer development with a height control of 150m SHD and a Gross Plot Ratio of 2.1.
Also located in a nice residential neighbourhood, and a city-fringe location, just a bit outside of RCR.
If I have to choose between the 2 for own-stay , I will choose Pine Grove.
Some may say that there could be a CRL station, but I think more likely along Clementi Road outside Maju Camp area. Pine Grove will not be walking distance from this new CRL station which is still 15-20 years from completion.
Most Pine Grove buyers will likely drive so lack of MRT should not be an issue.
