You can take a look at the tender documents for the BR plot (22,094.4 sqm) - See Tender Brief

Now take a look at the rezoned educational plot:
www.ura.gov.sg/dc/mp2008/images/mp08-120.pdf
See the plot size for the full parcel (including rezoned plot) = 22,094.4 sqm.
So the rezoned plot (in shaded colour) is part of the BR plot, and not any external plot next to BR.
If you are wondering why this rezone is only approved in 2012 while the tender is in 2011, sorry I do not know.
But the bottom line is that the rezoned plot is part of the BR plot.
There is no other residential plot next to BR.
