An "Office Tower" is a tall building designed primarily for office use. These structures often feature multiple floors, with each floor housing various businesses, organizations, or government offices. Office towers are typically located in urban areas, providing a centralized space for work and collaboration. Many office towers include amenities such as elevators, conference rooms, and parking facilities. They may also have retail spaces on the ground floor, offering services like cafes or shops. Notable examples of office towers include the Willis Tower in Chicago and the Burj Khalifa in Dubai, which serve as iconic landmarks in their respective cities.
