LTL Architects (Lewis.Tsurumaki.Lewis) is a design intensive architecture firm founded in 1997 by Paul Lewis, Marc Tsurumaki and David J. Lewis, located in New York City. Lewis.Tsurumaki.Lewis engages a diverse range of work, from large scale academic and cultural buildings to interiors and speculative research projects, and realizes inventive solutions that turn the very constraints of each project into the design trajectory, exploring opportunistic overlaps between space, program, form, budget and materials.

LTL has completed academic, institutional, residential and hospitality projects throughout the United States. LTL’s work has been recognized with many publications and awards, including the AIANY 2019 State Firm of the Year Award, the 2019 Interior Design Hall of Fame, the #3 Top Firm in Design from the Architect 50, a National Design Award, as well as multiple AIA design awards. The firm was featured in the U.S. Pavilion at the Venice Architecture Biennale and its work is in the permanent collections of the Museum of Modern Art, the San Francisco Museum of Modern Art and the Carnegie Museum of Art. The principals are co-authors of four acclaimed books: Manual of Section (Princeton Architectural Press, 2016), Intensities (Princeton Architectural Press, 2013), Opportunistic Architecture (Princeton Architectural Press, 2008), and Situation Normal…Pamphlet Architecture #21 (Princeton Architectural Press, 1998).
