LTL Architects is a New York City–based architecture and planning practice founded in 1997 by Paul Lewis, Marc Tsurumaki, and David J. Lewis. The firm pursues research-driven, material-intensive work intended to enhance civic life through the built environment. It is recognized for blending design innovation with unconventional pragmatism in projects for academic institutions and public entities, and it has expanded its exploration of carbon-sequestering materials as part of its design approach. Operating as a mid-sized practice, it focuses on complex, public-facing commissions in a city-centered context. A notable recent development is the 2023 release of its Manual of Biogenic House Sections. Earlier, Architect Magazine recognized the firm in 2018 as No. 3 on its Architect 50 ranking.
