MY STAB AT DP FOR INCREASE IN INTENSITY FOR TAMPINES COURT

Differential Premiums (to be paid by Buyer):
1) for Increase in Intensity of land (from low to higher plot ratio)
2) for Lease Top-Up (LUP) - topping up to 99 years for leasehold developments 
(you can't open the link because I am rethinking this - I can't compute Normanton's LUP so I figure there's something wrong with my computations...hmmm)

Looking at the Sale price Analysis slide (25 Aug 2017) the DP for increase in land intensity was given as $234,724,555.  They gave the existing plot ratio as 1.555 and it looks like they used the DC rate for Mar 2017 ($3500) instead of the Sep 2017 rate of $4200. Tampines Court was sold on 22 Aug 2017 - in the nick of time before the rate increase perhaps?

Note: the development baseline has not yet been ascertained. Using the lower PR is to the Buyer's advantage.
