The foundation of ESB is special that is strong enough to help holding this building up. When foundation was dug and then a cast-iron still was set into a base. The ESB has 6500 windows punctuate by delicate cast-iron columns created a rhythmic balance outside and well-lit space inside. The harmony of design with all the elements balanced in true classical form, is sheer elegance. The top five floors were chamfered their corner cut away and softened so that the building reached a logical denouement.
