I am being asked about the sectors nomenclature in DHA phase-2 extension:
Here is what I know about: seniors, pls correct if i missed something!
Old commoners town used to have 5 sectors which were took over by DHA-2.
One of five is mingled with DHA-2 proper, called sector-J. Other four are on the other side of islamabad highway: BCDE , now KLMN and DHA made more two alongside, called P & Q.
Rest is extension up to sector A-T
This is the best i could remember: am I right experts?
