Dont understand why u say that ur view was block at Ridgeview.. I was there surveying during the noon time on Sunday (4-6pm) and the evening time (8-10PM) just now.
The blocks facing south can have a good sea view, much better compared to the current blk 109 at depot heights.
If you are looking from 84, then you will be facing North where the view is blocked. Remember, Telok Blangah heights does not have a true North direction. You should be viewing from Block 68 (infront of blk 69) where you are in a straight line with the new Blk 70C facing the same direction. You will see the pinnacle, keppel country club and ECP from that view. Jus take the lift at Blk 68 to Level 15 and you will understand what i mean.
