Phase 1 was completed a few years before phases2/3/4 were completed in fact phase 4 was only released in early 2008 and the remaining blocks on phase 4 released in March 2009.
Each phase has its own president and administrator as well.
Phase 1 is also not part of the development site that contains phases 2/3/4/6/7/8 its across the road from the Xanit Hospital only a stone's throw away.
Phase 5 is suppose to be a hotel but nothing has started yet all the other phases 6/7/8 are completed but not released.
Hope this helps
Dave
