Enbridge occupies 95% of floors 25 through 36 in the 55-story CBD tower also known as Enterprise Plaza. D. Kyle Kelley, senior vice president with CB Richard Ellis in Houston, says the lease adds floors 23 and 24 to Enbridge's operations. Forest Oil Corp., which currently has the space, is consolidating operations on fewer floors, allowing Enbridge to take over the two floors later this year.

"The building is very full, but this worked out very well for them," says Kelley, who worked with CBRE's executive vice president Charles Gordon and vice president Lance McCarthy on behalf of the tenant. Houston-based Hines leases and manages the asset for EPCO Inc., which has its headquarters in roughly 300,000 sf of the multi-tenant building.

Kelley tells GlobeSt.com that Enbridge's growth has spurred its management to examine relocation possibilities, including under-construction office buildings in the CBD. The lease didn't expire until 2010 when the first of the buildings was set to come on line so Kelley says the option was doable. "The economics we were able to secure for the space at 1100 Louisiana made it an easy decision to stay," he adds. According to Hines' website, net lease quotes range from $18 per sf to $22 per sf.
