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 received a 2007 National Design Award, multiple AIA design awards and have been extensively published. LTL 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 the monographs, 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 work on the 70,000 square feet renovation for the Steinhardt School at NYU, the Living and Learning Center for Gallaudet University in Washington, DC and the Administrative Campus Center for the Claremont University Consortium in California. Currently, LTL Architects along with Perkins+Will and Thornton-Tomasetti, are undertaking the 160,000 square feet renovation of Upson Hall and the masterplan of the Engineering Quadrangle at Cornell University. Notable past projects include Arthouse at the Jones Center, Bornhuetter Hall at the College of Wooster, the Department of Social and Cultural Analysis at New York University, Fluff Bakery, and Xing Restaurant (recipient of the 2007 James Beard Award for restaurant design.) LTL Architects’ principals are on the faculty at Princeton University, Columbia University, and Parsons School of Design.
