The 60story Fountain Place tower in downtown Dallas is one of the city's most recognizable skyscrapers. The Hamilton is a 26-story tower in Dallas that offers floor-to-ceiling windows in every apartment.The building is 560 feet (171 m) tall and has 1,400,000 square feet (130,000 m2) of office space. It is also the tallest building in Dallas outside of Downtown. Allows for window washing. Fountain Place has windows that pop out for cleaning too. It's basically the only building in this little corner of Dallas downtown. If you bulldozed it, nothing would be there. The Infomart building is the fifth densest hub in the United States for banking, commerce, telecommunications, energy, medical research, and health care. This explains why the walls that face the older buildings on the site have no windows.
