Paul Building, National Register courthouse in Downtown Houston, United States

The Paul Building is an eight-story office high-rise at 1018 Preston Avenue in Houston, Texas. It is built of brown brick with load-bearing walls, and its terra cotta ornamentation includes several cartouches with a raised "P" for the original owner, Allen Paul.

Built in 1907, the structure soon housed a federal court that established itself in the business district. It changed hands and names multiple times throughout the 20th century while maintaining its original framework.

The building's name honours Allen Paul, the original owner, whose raised "P" cartouches still decorate the terra cotta. It later became the Hoffman, Turnbow and Republic buildings, reflecting changing owners. Tenants over the years included a newspaper and the Y.M.C.A.

The Paul Building stands at 1018 Preston Avenue in Downtown Houston, near the county courthouse. It is an occupied office building, so the interior is not open to the public; the brown brick facade and terra cotta cartouches can be seen from the street.

Terra cotta cartouches on the facade carry a raised "P" for Allen Paul, the original owner. The building was listed on the National Register of Historic Places on April 6, 1979.
