Reinforced concrete was the major Construction material. The dome of the post-tension shell has been designed to expand with climatic changes; like all materials, concrete expands.
With as pan of 150 meter, the concrete shell expands out when it's hot and contracts when it cools. This has functioned well in the building, adding an organic feel to the architecture that is otherwise absent due to the presence of inflexible concrete structures, which are yet to be completed. The shells rest on six abutments that transfer the vertical loads to the diaphragm walls and horizontal loads to six tie beams.
Decent ring has-been operated by hydraulic jacks, which lift up the shells in order to allow the transfer of horizontal and vertical loads. The concrete skin of the shell was finished with foam on the exterior to provide thermal insulation and waterproofing. The interior skin is finished with a spray of polystyrene balls for acoustic purposes. Glazed skylights form details at the top of the shell to respond to the expansion.
The curtain wall is fixed on steel Columns/where the glazing is placed at the point on the top of the shell where a setback is formed. This was positioned to prevent any horizontal or vertical movement and to prevent the glass from being broken. The lateral facades are all glass (with double glazing for thermal insulation and a special system of support allowing for expansion and retraction of the concrete shells) and, along with translucent, diffusive skylights offer a very efficient natural lighting.
In other subsidiary parts of the building ceramic tiles were used. These are found covering the segmental vaults of the linking galleries, on the shafts of the main entrance columns and lining the fountains; beneath the shell, air-conditioning units stand out amid the open spaces like oversized stainless-steel clad mushrooms.
In the absence of slabs and the opportunity to create ceiling ducts in the club building and linking galleries, the air-conditioning ducts from the basement floors were directed to these freestanding units to provide cooling for the internal spaces. Though white Carrara marble dominates most of the interior, covering the floors and walls, in the VIP areas the marble-clad walls are book matched. To execute the book-match design the marble was ordered from a quarry in Italy where single 3 by 1.2 meter slabs were specially cut. Apart from the touch of color found in the fabrics of the furniture and the wall-to-wall carpeting, which are confined to the entertainment and reception spaces, everything under the shell is white with no other form of decoration or ornament. Terrazzo tiling is also used on the ground floor’s internal south- facing garden, which is lined by the cascading fountains that flow down from the first floor.
