The Haj Terminal of the Jeddah International Airport
This Terminal was built to accommodate the pilgrims on their way to Mecca during the holy month. Up to 100,000 people pass through it in one day.
The fabric roof covers 430,000 sq.m. of plan area which is by far the largest roof structure in the world. Made of Teflon coated fiberglass the roof reflects most of the heat. Acting like a forest in the desert it provides comfort without requiring mechanical energy.
The roof consists of 10 modules of 320m by 138m, each having 21 tentlike units. Their peaks are suspended from steel pylons leaving the space under the units wide open.
Completion Date: 1982.
Cost of the roof structure: $ 180 million.
