Introducing PMX 35: Our model for how tall timber buildings could work in cities | by Cara Eckholm | Sidewalk Talk | Medium

Timber was once the dominant material for constructing new buildings, with early timber structures dating as far back as the Neolithic Age.* Yet timber fell out of favor in the late-19th century when steel and concrete gave buildings the strength to soar to new heights, meeting the need for urban density. Today, timber is staging a comeback in the form of a new fire-resistant super wood known as “mass timber,” a building material made of wood pieces compressed together in a factory to create thick beams, columns, and panels. This resurgence is driven in part by environmental advocates, some of whom have highlighted mass timber’s potential to help fight global climate change. Developers are also interested in how mass timber building parts lend themselves to efficient factory production, which can save time (and therefore cost) over existing on-site construction methods. These factors have spurred development projects that seek to incorporate mass timber into high-rise buildings. In fac
