Firm Profile



Lewis.Tsurumaki.Lewis (LTL Architects) is a design intensive architecture firm founded in 1997 by Paul Lewis, Marc Tsurumaki and David J. Lewis, located in New York City. LTL Architects engages a diverse range of work, from large scale academic and cultural buildings to interiors and speculative research projects. LTL Architects 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 Architects 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 2007 National Design Award and multiple AIA design awards. LTL Architects was featured in the U.S. Pavilion at the 2004 Venice Architecture Biennale and their 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).

LTL Architects recently completed the 23,800 SF renovation of The ContemporAry Austin – Jones Center (formerly Arthouse at the Jones Center), a contemporary art gallery in Austin, Texas. Currently, LTL Architects, along with Perkins+Will and Thornton-Tomasetti, is undertaking the 160,000 SF renovation of Upson Hall at Cornell University, scheduled to be completed Fall 2017. LTL Architects was also selected as one of 26 architecture firms to be pre-qualified to participate in the Design and Construction Excellence 2.0 by NYC’s Department of Design and Construction through 2019. Notable past projects include NYU Steinhardt School, Brown Institute for Media Innovation at Columbia University, Claremont University Consortium, and Arthouse at the Jones Center.
