MOS Architects is an architecture practice founded in 2003 by Michael Meredith and Hilary Sample, based in New York, United States, since 2011. Its practice combines architectural research with the development of projects at different scales, ranging from housing and educational buildings to installations, exhibitions, furniture, publications, and experimentation with digital tools.
Among its most notable projects are the Floating House on Lake Huron, Canada; the Element House in New Mexico; the Afterparty pavilion for MoMA PS1 in New York; the Petite École in Versailles, France; the studios at Krabbesholm School in Denmark; and the Chacarita Alta collective housing project in Asunción, Paraguay, developed in collaboration with Adamo-Faiden and Equipo de Arquitectura.
The practice has received numerous awards and distinctions, including the Emerging Voices Award from the Architectural League of New York (2008), the Academy Award in Architecture from the American Academy of Arts and Letters (2010), the National Design Award in Architecture from the Cooper Hewitt, Smithsonian Design Museum (2015), and the United States Artists Fellowship (2020). In 2025, it received a Holcim Foundation Award for Latin America for the Chacarita Alta housing project in Asunción. That same year, both founders were elected members of the National Academy of Design.
