The planned city was designed in 1948 to house the capital. It is subdivided into units, each with a high school, shopping centres, dispensaries and play areas. While most of the units house government employees, Unit V houses the administrative buildings, including the State Secretariat, State Assembly, and the Raj Bhavan. Private residential areas were later built in other areas of the planned city, including Saheed Nagar and Satya Nagar. Unit I, popularly known as the Market Building, was formed to cater to the shopping needs of the new capital's residents. Later, markets and commercial establishments developed along the Janpath and Cuttack-Puri Road at Saheed Nagar, Satya Nagar, Bapuji Nagar and Ashok Nagar. A dedicated institutional area houses educational and research institutes, including Utkal University, the Institute of Physics, the Institute of Minerals and Materials Technology and Sainik School. Indira Gandhi Park, Gandhi Park and the Biju Patnaik Park are located in the unit.
