Mitsubishi Takes Four Floors of Houston Office Tower

The central business district asset rises 55 stories.

Mitsubishi Corp. (Americas) has inked a lease for 91,761 square feet at 1100 Louisiana, an office tower in Houston’s central business district. The Japanese manufacturer will occupy floors 31 to 34 of the 1.3 million-square-foot tower, which rises 55 stories and includes a small amount of retail and 13 levels of parking.

Energy specialist Enterprise Products Partners, which is headquartered in the building, acquired it in 2005 from Hines Interests. The property was developed in 1980 during an energy boom in Houston.

1100 Louisiana, which is LEED Gold certified, also counts as transit-oriented, with access to two Houston Metro stations downtown.

Partners Real Estate Senior Vice President Diana Bridger and Partner Winfield Haggard Jr. represented the landlord in the transaction. Cushman & Wakefield Executive Vice Chairman Tim Relyea represented Mitsubishi.

Mitsubishi is moving from 1221 McKinney St. in downtown Houston. The firm’s U.S. headquarters is located in New York.

A purchase price was not disclosed.

In March, First Community Credit Union acquired the former Noble Energy Center Two, a 470,623-square-foot office tower in Houston’s Vintage Park/Tomball area. The building will servea as FCCU’s new corporate headquarters.
