I belief this is only a dream project, probably a thesis for graduation ? Are you in the A&B faculty ? Of course personally I would want Punggol End to be developed into a place for leisure, a little bit swampy to attract birds, kampong style, where we can go bird watching, catching spiders, fishing, sampan rowing, climbing coconut trees, and a place where we can do some exploration. Of course a few attap chalets for overnight accomodation.
....no need electricity....kerosene lamps will do. Aha.....maybe include some secluded corners for a beer and groundnut session with old friends...........
Goodluck...........
