Given the environmental and material challenges that frame architectural practice in the twenty-first century, the section provides a rich and under-explored opportunity for inventively reimagining the intersection of structural, thermal, and functional forces. Moreover, the section is the site where space, form, and material intersect with human experience, establishing most clearly the relationship of the body to the building as well as the interplay between architecture and its context.
ARCHITECTEM met with Paul Lewis of LTL Architects to discuss their most recent publication aptly titled Manual of Section, presenting a framework for describing and evaluating Section as well as a lexicon of different types of sections and their functions. Featuring essays on the history of section and its role in architectural design, LTL Architects founders Paul Lewis, Marc Tsurumaki, and David J. Lewis, describe the seven categories of section they developed—Extrusion, Stack, Shape, Shear, Hole, Incline, and Nest. Relying on extensive archival research. These sectional categories are illustrated through 63 detailed cross- section perspective drawings of significant structures built around the world over the past 100 years.
