This project is located in Ajman U.A.E. along the Persian Gulf, a resort hotel of 250 guest rooms. The site, roughly square, directly facing the beach for 250m, has a depth of approximately 300m. The circular route along the outer site perimeter by electric carts achieves a short-time connection between the guest rooms and the common facilities: the hotel reception, the restaurants, the spa and the beach. All rooms face the sea, creating three distinct zones from one to six storeys of different room types. In order to ensure quality and reduced construction time, a square tube form precast concrete that is stacked structure was proposed. Structural rationality, differences in unit types and the effective use of spaces created between units was taken into consideration to create a variety of unique spaces.
