Museo Casa Sobre el Arroyo (House on the Creek Museum), Mar del Plata

House on the Creek Museum is a significant architectural work designed by Amancio Williams and Delfina Galvez Bunge. The house, also known as Casa del Puente, has been recognized for its cultural, historical, and environmental importance by various institutions, including the Municipality of General Pueyrredón and the Province of Buenos Aires. It is a key example of the Modern Movement in architecture, known for its originality and precise construction.

The museum is an integrated architectural and natural landscape. The property includes a historic park and two main structures that harmonize with the surrounding environment, reflecting logical and mathematical design principles. The house spans a stream, connecting both sides of the terrain, which is a unique feature of its design.

House on the Creek Museum is noted for its minimalist approach, with all elements serving specific functions. The materials used, such as red carob paving stones, cedar plywood, and reconstituted granite, contribute to its modernist aesthetic. The house also features custom-designed lighting and a unique folding door inspired by aeronautical technology.

The interior spaces, including a music studio dedicated to composer Alberto Williams, were carefully designed to blend with the natural surroundings, allowing sounds from the stream and birds to be integrated into the experience.
