1000 Main was constructed from 2001 to 2003 and has 36 floors. It is the 25th tallest building in Houston. It is made out of glass, steel, and concrete. Lights atop the building and on the main street side flash in patterns of various colors at night. This building occupies the site where the Lamar Hotel stood before it was demolished in 1985. A two-level trading floor with 30 ft high ceilings, currently leased by the trading arm of Shell plc, is located on the 10th and 11th floors. It is squeezed between the garage and the office tower.[citation needed] Century development built the Reliant Energy Plaza.
