Transwestern delivers 30-story Uptown tower

​​HOUSTON – Transwestern has completed construction on Australia-based mining company BHP Billiton Petroleum’s new 30-story office tower at 1500 Post Oak Blvd. in Uptown. 

Transwestern broke ground in late 2013 on the TIAA-owned high-rise, which is located within the 1.75 million-square-foot Four Oaks Place office park situated between San Felipe Rd. and Loop 610.

BHP will occupy the entire building along with the company’s space at 1360 Post Oak Blvd. ​​​It plans to consolidate its employees spread throughout the area and Tulsa, Okla.

Designed by Pickard Chilton Architects, the 593,856-square-foot tower has been designed to achieve LEED-CS Gold certification and incorporates seven levels of parking as well as a skybridge that connects​ to BHP’s current headquarters.  ​​​
