History
The area that became the Allen Center was originally considered to be an eastern portion of the Fourth Ward. The opening of Interstate 45 in the 1950s separated the eastern portion from the rest of the Fourth Ward; that portion became the Allen Center and is now considered to be a part of Downtown Houston.
TrizecHahn Properties acquired the Allen Center in 1996. Trizec defeated 16 other real estate companies so it could purchase the center for an amount reported by Tanya Rutledge of the Houston Business Journal as $270 million.
When Trizec acquired the Allen Center in November 1996, the complex had a 76 percent occupancy rate. By 1997, Trizec had convinced several tenants of the Cullen Center, also owned by Trizec, to relocate to the Allen Center. Paul Layne, a vice president of the office division of Trizec, said that the shifting of tenants would lead to Allen Center having an occupancy rate of 92 percent in 1998.
In 2001, when Enron collapsed, it vacated 800,000 square feet (74,000 m2) of space in the Allen Center and Cullen Center complexes in Downtown Houston.
In 2010 Devon Energy was trying to sublease about 125,000 square feet (11,600 m2) of space that it occupies in the Allen Center complex. Hess Corporation will vacate around 500,000 square feet (46,000 m2) of space in the complex when a new office tower in the east side of Downtown Houston opens.

1400 Smith Street was known as Four Allen Center.
The building was the former headquarters of Enron, one of America's largest commodities trading companies during the 1990s and later infamous for its financial scandal in 2001. Enron occupied the building after relocating to Dallas in 1985. Before Enron's collapse, the energy giant constructed a second, similar building across the street, connected to 1400 Smith Street by a circular skywalk.
In 2006 Brookfield Properties acquired the 1,200,000-square-foot (110,000 m2) Four Allen Center for $120 million. At the same time Brookfield announced that Chevron USA signed a lease for the entire building. Brookfield held 4 Allen Center in a joint partnership with the private equity group The Blackstone Group. As of 2006 the joint venture has 7,400,000 square feet (690,000 m2) of office space in Downtown Houston, making it the largest office owner in the central business district.
Beginning in 2006 Chevron leased the entirety of the building. In June 2011 Chevron bought the building from Brookfield for $340 million.
