The first planned residential colonies in Valasaravakkam made their appearance during the Second World War. Prior to the war, Valasaravakkam was a small village forming a part of the Saidapet taluk of Chingleput district. Due to its remoteness, development took place at a slow pace until the 1980s. Its strategic location on the Arcot Road has resulted in accelerated growth since then.
