Recently, they have finished the Hotel Yas that houses up to 500 rooms at a surface of 85 000 square meters. This luxurious hotel is one of the most significant buildings of an ambitious 36 billion harbor Yas located near-by the F1 circuit in Abu Dhabi, United Arab Emirates. The initial concept of the project was to give geometrical and aesthetical expression to speed and movement, as well as islam art and craft traditions. The main element of a 217 meters high facade is a steel construction that has not only an architectural importanca but engineering as well. This construction visually interconnects two individual hotel towers. The entire project reacts with its surroundings and modifies it visually.
