The Palmira López de Pereyó House, a 1930 residence in Humacao, Puerto Rico, exemplifies Prairie School architecture as interpreted in the Caribbean. Designed by Francisco Valinés Cofresí—a self-taught architect educated through correspondence study with the International Correspondence School in Scranton, Pennsylvania—the house demonstrates how this American modernist style was adapted to tropical conditions. The Prairie School aesthetic, which arrived in Puerto Rico primarily through architect Antonin Nechodoma's work and reflected the influence of Frank Lloyd Wright, proved ideally suited to the island: it harmonized contemporary design principles with traditional tropical features including deep balconies, terraces, galleries, shutters, French doors, and covered ceilings that provided ventilation and shade. Built for Luis Pereyó y Rodríguez, a District Court judge, and his wife Palmira, the residence was added to the United States National Register of Historic Places in 1995 and the Puerto Rico Register of Historic Sites and Zones in 2001.
