It was originally designed as a diplomatic club, but is now used by the Saudi Government as a hospitality centre that introduces Saudi cultural life to the international community. Completed and opened in late 1985, the architectural concept comprises a central building that forms the backbone of the complex, winding in and around on itself over a distance of 800 metres and housing luxury guest accommodation. Five large tents radiate from this spine, which contain lounges, reception areas, multi-purpose halls, conference facilities, restaurants and a library. The design also accommodates sports facilities and landscape gardens within the inner courtyards and outer spaces, created by the curves of the central spine. In response to the Riyadh climate and the opportunities presented by the site itself, the BuroHappold Engineering team worked closely with the architect to develop the concept of a central spine that anchors five tents. The solid form of the spine is clad in local limestone so as to blend in with the topography while also offering further insulation for the building to reduce unwanted heat gain from the powerful sun. The terraced spaces created within its curves echo those on the edge of the Wadi, further rooting the complex within its surroundings. The tents are a nod towards the architecture of the nomadic communities that live on the fringes of the urban fabric. Our engineers took careful consideration of the materials used, resulting in the use of a white, Teflon-coated, woven fibre fabric for the canopies that would reflect the glare of the sun in the summer months. In addition, a second membrane of lightweight Teflon-coated cloth serves as a false ceiling inside the tents, adding a further shield against solar glare while also hiding the cable mesh structure that gives TUWAIQ PALACE RIYADH, SAUDI ARABIA Images © Joe Poon A DESERT ROSE
