Reflecting on the first two decades of their eponymous practice and the recent release of the firm’s monograph “Johnsen Schmaling: On Rigor,” Brian Johnsen and Sebastian Schmaling will discuss the importance of conceptual rigor and formal restraint in their work — “skillfully assembled, simple forms with a reductive logic whose outcomes seem, like the best poetry, both novel and inevitable” (Architect magazine), and “a collection of buildings of near-monastic simplicity with a sense of place and an unfussy precision” (Architectural Record). Looking at both recent and earlier projects, Johnsen and Schmaling will argue that rigor is not a constricting force but one that is aesthetically liberating and, increasingly, environmentally imperative.
