Why it's listed
Rising twelve floors above Main Street in downtown Houston, this former bank and office building was designed by architect Alfred C. Finn and built between 1922 and 1924. Its base is rusticated granite, carved with the motto "Frugality is the Mother of Virtues," and its upper floors carry fluted pilasters, arched windows and a tiled penthouse topped by a copper-spired lantern. Inside, the banking lobby and mezzanine had ornately carved plaster ceilings, and the vaults were placed in the basement. The State National Bank, founded in 1915 as the State Bank and Trust Company, occupied the building until a 1946 merger. A 1948 renovation covered the facade in limestone and filled in the mezzanine. In 1981 the limestone was removed so restoration could begin. The building is valued as an early work by Finn and as one of the few surviving Neo-Classical skyscrapers in Houston, with much of its Beaux Arts detail intact.
Significance in brief: The building is significant as an early commercial work by Alfred C. Finn, one of the Southwest's most respected early 20th century architects. It is also one of the few surviving Neo-Classical skyscrapers in Houston. Much of its Beaux Arts detailing survives, and missing elements were being reconstructed.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
