The Allen Center complex in Houston.

The Allen Center is a group of tall buildings in Downtown Houston, Texas. It's like a small city within the city! This complex has offices, shops, and places to eat. It includes three main buildings: One Allen Center, Two Allen Center, and Three Allen Center. Together, they offer about 3,000,000 square feet (280,000 m2) of space. That's a lot of room for businesses and people!

History of the Allen Center

The land where the Allen Center now stands was once part of an older neighborhood called the Fourth Ward. In the 1950s, a big highway, Interstate 45, was built. This highway separated this part of the Fourth Ward from the rest. This separated area then became what we know today as the Allen Center. It is now considered part of Downtown Houston.

In 1996, a company called TrizecHahn Properties bought the Allen Center. They bought it for a large sum of money, showing how important this complex was. At that time, about 76% of the spaces in the buildings were rented out.

By 1997, TrizecHahn worked to fill more of the buildings. They even convinced some businesses from another building they owned, the Cullen Center, to move to the Allen Center. This helped the Allen Center become almost fully rented, with about 92% of its spaces occupied by 1998.

Later, in 2001, a large company called Enron faced problems. When it closed, it left empty about 800,000 square feet (74,000 m2) of space in the Allen Center and Cullen Center. This shows how big companies can impact office spaces.

In 2010, some companies started to move or reduce their space in the Allen Center. For example, Devon Energy tried to rent out some of its space. Also, Hess Corporation planned to leave about 500,000 square feet (46,000 m2) of space when its new office tower opened.
