One Shell Plaza, 910 Louisiana, was the first skyscraper built by master developer Gerald D. Hines.

In Houston, Ontellus, the nation’s largest privately-held data retrieval and claims intelligence provider, is moving its national headquarters to the 910 Louisiana building in downtown Houston.

The move to the 910 Louisiana tower from the 1010 Lamar Street building is planned for late 2019.
