Tuwaiq Palace • Recipient of the Aga Khan Award for Architecture, 1998.
Tuwaiq Palace • enclosed by inclined curved walls, forming a sinuous curvilinear spine 800 m long, 12 m high, and 7-13 m wide, used for guest services and accommodations • outdoor sports facilities, gardens, and extensive landscaping laid out in a pattern of complementary spirals, circles, and curves, in harmony with the building's undulations
Mushrooming from the spine are tents supported by tensile-structure technology • design makes reference to two local archetypes - the fortress and the tent
The tents enclose the large-scale spaces: main lounges, reception areas, multi-purpose halls, restaurants, and a café • dramatic contrast between the lush greenery of the outdoor spaces enclosed by the spine and the arid rocky plateau beyond its walls • The white tents are made of Teflon-coated, woven fibre fabric • The tents are enclosed by glass walls
