File includes 13 drawings (1 site plan, 7 plans, 2 sections, 2 elevations; 1 combination drawing: 1 section/elevation), 2 presentation boards (1 site plan, 1 plan I perspective), and 35 prints of model. The Air Defense Headquarters houses the Office of the Commander of the Air Defense Forces and his assistants, Research and Development, the Directorate of Planning Projects, Public Relations, the Finance, Military and Civilian Personnel Departments, to name a few. In addition, the Headquarters incorporates a mosque, barracks and a mess hall into its scheme. The site is approximately 4 hectares with walls bermed on all sides. This prevents water drainage into the Headquarters, as well as acting as a security wall. The site is divided into three zones: a service zone; a transitional zone, formally landscaped to create an appropriate entry for the Headquarter Building; and the platform zone, on which the building sits. A central spine divides the site in a north-south orientation, which also acts as an artery for all the shared facilities. The 20 250 m2 building is a limestone-clad stepped pyramid, taking full advantage of the desert light. Its height was restricted by the flight path of a nearby airport and consequently the gardens and entrance are below grade level. The roof is also stepped in form, a concrete shield sheltering an inner landscaped garden, which all administrative offices face.

The SANCST Science Halls were conceived as a demonstration centre showing the development of science within the Muslim world, and making science accessible to all. The 125 hectare site was 12 km north of the Riyadh centre core. The entry was to be through a large semi-circular plaza from which both the Headquarters Building and the Science Halls could be accessed. The Headquarters Building possesses a strong central axis and the Science Halls are located near the far end of the site. The latter is set on an oblique angle giving it dual orientation. It also uses a strong system of Islamic geometric ordering, superimposition and the rotation of the basic square. The Science Halls have a traditional introverted character and the building mass sits on the Arabic landscape like a finite object, particularly in its use of natural materials. The exterior cladding is a warm colour of horizontally stratified Riyadh limestone with varying band depths. The important features of the Science Halls are the arrival plaza and its orientation, the souk street circulation, the laboratories, the demonstration theatres, the formal gardens, the traditional riverbed gardens, and the medicinal herb gardens.
