Sector 21and 25 - two sectors combine to make Noida's well known neighbourhood Jal Vayu Vihar. Built by Air Force Naval Housing Board (AFNHB) between 1984 and 1998, the original allottes were Air Force and Navy personals. The funding for the apartments was done through self finance schemes with every home buyer depositing about 10% of the expected price of the flat at the time of registration - balance to be paid in easy instalments. Spread on a total area of 25 acres, this sprawling neighbourhood  is an assortment of 2, 3, 4 and 5 BHK apartments, managed by Jal Vayu Vihar Sehkari Awas Samiti. There are enough markets within Jal Vayu Vihar to cater to all your needs, but it is the CSD canteen run by Air Force and Navy which is the most popular for residents belonging to the armed forces thanks to its concessional rates. The Society has its own community centre called JVCC (Jal Vayu Vihar Community Centre). For sports enthusiasts Noida Stadium, just a walking distance away from Sector 21, is where one plays football, cricket, badminton, etc.
