The repositioning of the 1100 Milam Building to the headquarters of Houston Industries is one of Houston's landmark real estate development projects. The redevelopment plan called for gutting the 47-story building wall to wall. Equipment and materials had to be put into place in a careful sequence with only the sidewalks as the layout space. Tellepsen completed the interior construction of the headquarters offices. The transformation of the building was a unique example of the symbiosis between architecture, investment and urban revitalization. The redesign created a symbol of the company that is visible 24 hours a day. CenterPoint Energy, the successor company, is still widely recognized by the lantern in the sky that rises above the downtown Houston skyline.
