This tower was originally build to house the 350, 000 employees of Sears, the then the largest retailer in the world. It was decided that they would rent out the remaining space which was left idle after housing the huge army of the employees. The rest of space would be rented out to law firms as well as banking firms. Keeping this aspect in mind the size of the floor was small which helped in constructing a skyscraper. This also lent an attractive exterior to the building. After the completion of the tower, it eventually surpassed the World Trade Centre in New York. The total construction charges of this tower were $175 million. The tower is held by squared shaped tubes which have floors suspended in it.
