HHF Architects was founded in 2003 by Tilo Herlach, Simon Hartmann and Simon Frommenwiler. Since then, HHF Architects have realized numerous projects in Switzerland, Germany, China, France, Mexico and the USA. The scope of work ranges from urbanism and large-scale construction to public pavilions and interior design.
From the beginning HHF was looking for collaborations with other architects and artists in order to widen their view on projects and enrich the quality of specific proposals. In this context, worldwide perceived group projects such as "Ruta del Peregrino" and the fruitful collaboration with the Chinese artist Ai Weiwei emerged.
In addition to building, teaching is an important activity of the office. The principals of HHF were visiting professors at the University of Innsbruck, the Karlsruhe institute of Technology KIT and MIT School of Architecture and Planning in Boston. Since fall 2018 the principals of HHF are teaching at Yale School of Architecture and Harvard Graduate School of Design. HHF also participated as jury members at numerous universities worldwide.
HHF has been honored with numerous national and international awards and invited to several international Biennials, including the Bi-City Shenzen/Hong Kong Biennial, the 13th and 14th Venice Architecture Biennale, and the Chicago Architecture Biennial 2017. They where honored with the Wallpaper Design Award and winning the important German "Häuser des Jahres" Award, a Berlin Architecture Award, and where honored for the best new building by the Basel Heritage Protection. In 2015 they won the gold award in the Housing category at the Swiss Architecture Awards. Their work is part of the permanent collections of Centre Pompidou in Paris, the Architekturmuseum der TU München at the Pinakothek der Moderne in Munich, and the Heinz Architectural Center at the Carnegie Museum of Art in Pittsburgh.
