Role of Keystone Restoration     

Our firm served as general contractor for the restoration of one of Puerto Rico's oldest buildings, the U.S. Customs House. Listed in the National Register of Historic Places, our work not only adhered to the Secretary of the Interior's Standards for Historic Rehabilitation, but   also met demanding standards for security and operations. Originally built in 1838 as a hostel for the wealthy, this Neoclassical, Greek Revival building was converted into a Customs House in 1898 when Puerto Rico was annexed by the U.S. In 1918 the building was severely damaged by an earthquake and subsequently reconstructed in 1922.

In addition, we added second floor offices complete with bullet-resistant glass and a prison cell. The U. S. Customs House in Mayaguez is still in active use as a custom facility and has been extensively published in books and newspapers. Our project won an award from El Colegio de Arquitectos de Puerto Rico in 1996.
