Prior to its redevelopment, O. R. Tambo International Airport comprised a disjointed and disparate series of buildings lining the airports airside/landside interface; a multi-level international terminal building dating from the early 1970s, and three separate single level domestic terminals varying in age from as early as the 1950s. In response to substantial growth in passenger numbers experienced post 1994, O. R. Tambo has undergone a series of large scale extension and redevelopment projects, beginning in the late 1990s. 

The final piece in the puzzle, came to completion in 2009, a year prior to the 2010 FIFA World Cup, was the new 120 000m2 Central Terminal Building (CTB), which united for the first time under a single roof an 800 metre long terminal precinct, which expanded the precinct’s passenger processing capacity to 28MAP. The CTB acts both as an integrator and a centrepiece within the airport’s Western Precinct, tying the disparate levels of the various existing terminal buildings together and providing additional terminal capacity, as well as a large increase in retail footprint, in line with the international trend towards increasing non-aeronautical revenue for the airport operator, through enlarged airside and landside retail offering. 

Located at the point of intersection of international passenger arrivals, north-south intra-terminal circulation routes, and movement routes from the parkades, bus terminal and Gautrain station, the CTB’s centrepiece is its giant oval atrium, which punctures all levels of the terminal building, allowing natural light to wash the building’s deep floor plates. As a gathering and meeting place, and point of orientation, the atrium is the central square in the city that O. R. Tambo has become.

King Shaka International Airport (KSIA) is the first major green field airport to be developed on the African continent for 40 years. The decision was taken to relocate airport operations from the old Durban International Airport south of Durban to a green field site north of the city with a view to providing an initial capacity of 7.5MAP, expandable up to a future ultimate capacity of 45MAP. Osmond Lange was invited by Ilembe (Pty) Ltd, a consortium of building contractors formed to bid for the design-and-build contract for KSIA, to assemble and lead a group of Architectural firms and specialised sub-consultants. The scope of work included the design of more than 70 buildings, the largest and most significant of which is the 103 000m2 six level terminal building. 

The terminal is divided into two main elements: 

  • The processor that accommodates all the facilities to process passengers and baggage as well as the retail, administration and technical spaces 

  • The Airside Corridor that constitutes the circulation route and interface element between the Processor and the aircraft 


Structurally the building is designed with a combination of a conventional reinforced concrete frame with 15 x 15 spans and a long span steel roof. This approach allows for economy, speed of construction and the provision of large, column free spaces at the upper level public areas. It also facilitates the incorporation of roof monitors designed to bring natural light into the building. 

As the IAJV leader, Osmond Lange was responsible for the management of the Joint Venture including: 

  • Design leadership 

  • Management and Interface with the JV member firms at design and administrative level 

  • Interfaces with Client, Contractor, Local Authorities and ACSA (Airports Company South Africa) 

  • Interfaces with Consultants of all disciplines involved in the project 

  • Management of the Passenger Terminal building Design and Documentation team 

  • Programming, Reporting and press releases 

  • IAJV financial management 

  • Quality Assurance

As an extension of our work on the O. R. Tambo Master Coordination Plan, Osmond Lange prepared an Urban Development Framework for a proposed commercial development adjoining the existing Western Terminal Precinct at O. R. Tambo International Airport.


The framework focused on 7 hectares of developable land located in a series of islands enclosed within the terminal’s access road system. The proposed development comprises the decking of these land parcels to form an artificial ground plane for a proposed mixed use precinct, laid out on the principles of New Urbanism, connecting directly to the retail mezzanine of the terminal buildings, and to the airport’s Gautrain Station. The proposed development comprises 220 000m2 total bulk, including retail, offices, hotels and a convention centre, as well as 5 400 new parking bays.
