When I was still managing the area, I recalled their submission to take over the former Dhoby Ghaut Open Space and convert it into a campus grounds for their students. Their plan was to conserve the Angsana trees within the area and I wondered how they intended to do it. It's not possible to see from the photos but an Angsana tree was heavily pruned and appeared to be wedged between and below the buildings.
What they did was innovative but it is not necessary good for the tree.
