World Monuments Fund (WMF) announces the Ministerios de Cultura y de Obras Públicas de Argentina y Municipalidad de Mar del Plata (Ministries of Culture and Public Works of Argentina and the Municipality of Mar del Plata) as the winner of the 2024 World Monuments Fund/Knoll Modernism Prize, recognizing the commission’s thoughtful and detailed conservation of la Casa sobre el Arroyo (the House on the Stream).

The combined value of WMF’s commitment to the conservation of important cultural icons and Knoll’s ethos in using modern sustainable design to connect people in meaningful ways inspired the creation of this award.

Forward-thinking. Experimental. Bold. Progressive. Innovative. Once recognized for these defining characteristics, significant modern structures around the world often fall victim to material deterioration, perceived obsolescence, and public apathy. These threats repeatedly result in inappropriate alterations or demolition. As many of these modern buildings are too young to qualify for landmark designation and protection, the need for preservation and increased public awareness of these unique resources is urgent.

WMF launched the biennial World Monuments Fund/Knoll Modernism Prize with founding sponsor Knoll in 2008 to recognize the individuals and organizations that preserve our modern built heritage through pioneering architectural and design solutions. The prize honors contemporary architects and preservationists whose work ensures sustainable futures for at-risk modern heritage.

The prize is part of WMF’s broader programming that addresses these challenges facing modern sites through advocacy, education, and conservation, including the World Monuments Watch. The prize stemmed from WMF’s Modernism at Risk initiative, created in 2006 in response to the increasing threats to buildings representative of the modern movement.

The World Monuments Fund/Knoll Modernism Prize recognizes outstanding physical interventions to preserve modern heritage. Projects that enhance a site’s architectural, economic, and environmental sustainability while engaging and benefiting local stakeholders are encouraged.
