SOME PLANS IN THEIR WRENCH And who thought a building shaped like a pipe wrench wouldn’t attract a natural-gas firm as its lead tenant? Hines announced yesterday that UK-based BG Group will move its Houston offices from the Panhandle Energy Tower where Westheimer hits Alabama in the Galleria to MainPlace, the Pickard Chilton-designed spec building still under construction at 811 Main St. Downtown. The company will take over floors 29 through 34 in the 46-story tower, but may fill up more later. And it’s changing the building’s name — no, not to Pez Tower — but to BG Group Place. KPMG put dibs on the building’s top 4 floors more than 2 years ago. [Houston Chronicle; previously on Swamplot] Photo: Skyscraper Page user Johnme
