The external walls of the building are made from concrete and steel to provide pretection against weather, and to offer sufficient strength to support the floor and roof structures. The interior walls are built of long-durable bricks and are coloured to brighten up the hotel. The wall materials are very durable and are easy to maintain and innovate. Selected concrete tiles are used on the flat roof and the multiple tile layers serve a a moisture barrier.
