In this episode Paul Lewis, Marc Tsurumaki, and David J. Lewis of LTL Architects speak about the “productive oscillation” between academic research, speculative drawing, and the material realities of building that defines their practice; LTL’s trajectory from the “opportunistic” spatial inventions of early New York interiors to an existential focus on biogenic materialities and the climate crisis; and their publications that reorient both the classroom and the construction site.
