Justin Den Herder’s love of trees and poetry have informed his 17-year career as a structural engineer at TYLin. He cares deeply about the impact of the built environment on the natural world and leads the firm’s sustainability, mass timber, and computational design communities of practice. He oversees the firm’s Building Equity Initiative which offers pro- & lo-bono design services to public and non-profit programs. Justin has collaborated on more than 500 projects. He is especially fond of working on reuse projects and takes pride in designing public projects – libraries, museums and other civic institutions. His class at Cooper Union at the Irwin S. Chanin School of Architecture, titled ‘Structural Poetics’ explores the creation of efficient, elegant, equitable structures.
