The Burj Dubai is composed of a foundation and three wings, each of which is at a different altitude and will reduce the size of the building's construction. The arrangement of the wings creates a spiral staircase to the left that encircle the structure and assists to counteract the high winds and many sandstorms that occur in Dubai. The foundations of the building are made of crushed rock that has been cemented together. The wing on the third floor is just for show. It was added when the owner wanted to have more space than the law allowed for. The only thing it contains now are luxury apartments that go for about $500,000 or more. The rest of the space is used for parking. The wing on the first floor is where most of the action takes place. Here you'll find the revolving door and the elevators that take guests to the various floors. The main entrance of the building is located on the ground floor near the center of the structure. From here you can see the entire building, including the top floor where the restaurant is found. Guests can choose to enter the tower either through the main entrance or one of the four side entrances which contain shops or restaurants on each floor. Each room in the hotel includes two windows that face outside, allowing natural light into the apartment during the day and electricity at night to help with cooling and heating. There are also two smaller windows on the side walls for extra sunlight.
