Developed in 1980 by Hines, 1100 Louisiana is a 55-story, 1.3-million-square-foot office building located in the heart of Houston's primary energy and financial corridor. The tower is clad in polished Spanish Rose granite with rose-colored windows. The south and east curtainwall contains a series of large stepped bays at the top of the building. 1100 Louisiana contains 44,046 square feet of retail space and a 2,234-car parking facility adjacent to the building that is accessible via the downtown tunnel system. The tower rises from a grand plaza that occupies almost a quarter of the block. The project was sold in November 2005 by National Office Partners Limited Partnership (NOP), a joint venture between Hines and the California Public Employees' Retirement System (CalPERS) to Fantome Tower LP.
