After World War II Khormaksar was planned and built according to the modern English-style with all the necessary facilities. Further more, the Military Airport was renovated and a new airport was constructed which is known today as Aden International Airport. This was followed by the construction of several wooden houses, some of which consists of two floors and some other one-story English style houses and constructed Elizabeth II Hospital which was hospital in Aden.

It consisted of a number of large apartment buildings, new streets were paved and all supporting facilities such as schools, public colleges, public parks, casinos and discothèques, cinemas and hotels were built. They were all built to serve the soldiers in the British Military Base of East Suez.
