@Javed - please be advised that Air Avenue and Park View were merged with DHA Lahore around 3 years ago and there is no more Air Avenue or Park View. They are called DHA Lahore Phase 8 now and managed and controlled by DHA. Some people / property agents are using their old names just because of identification purposes only. It is as safe as to invest in these societies as any other phases of DHA Lahore.
