Just an update on the gate between DM and HP; HP have submitted updated information to the coco on a number of items, among which one of them was about the gate. They have submitted a letter from the receiver responsible for DM giving blessing for opening it on their side and HP have said they will open it once the phase 2 is finished development. So looks like it will be open, albeit probably not until 2018/19...
Also, they are implying that the overlook from the proposed apartment block will not be much of a problem for DM; the orientation of the block means it's the 'end' of the block that will be facing DM and they are adding some extra balcony 'end-plates' to further obscure the overlook.
