800 Bell Street was built in 1963 as the headquarters of
Humble Oil Company, a predecessor of Exxon. In 2011 the company announced they would relocate all employees in the building to a new ExxonMobil office in
Spring. In 2015, as ExxonMobil's lease expired, oil prices crashed. This caused petroleum companies to shed excess office space, leaving the property vacant for almost the next decade. In September 2015 Parker's administration announced that the plan would not move forward due to concerns over costs. In late 2022, the 1.2 million square foot building was sold to developers with plans to convert the vacant office building to residential units. The building is situated about five blocks north of the
Pierce Elevated freeway, which is slated to be re-routed and removed as part of a Texas Department of Transportation Plan. ==Petroleum Club==
