Located in a particularly natural setting in the city of Mar del Plata, the "Casa sobre el Arroyo" (House on the River) - known as the "Casa del Puente" (The Bridge House) - is considered a paradigmatic component of 20th-century architecture and an obligatory reference of the Modern Movement in Argentina and Latin America.

The house designed by the Argentinean architect Amancio Williams, commissioned by his father, the musician Alberto Williams, is constructed evidence of the capacity to establish a link between the modern rationality of human beings with nature and its topography.
