Let’s zoom in on an area of prefabrication that was a major focus of the mid-19th century and now in the 21st century is building components. Turning to other industries like automobiles and airplanes, it’s clear that the assembly model and a componentized process of construction allows for more efficient and effective results. It is a compression member and therefore the column connection is required to be proper. Prefabrication is just not about concrete and modular systems, there is much more to that. Personally, I’m thrilled by the idea of what I’ve referred to as tier 2 “components” and developing systems similar to Gropius and Wachsmann for project 28x30 – 21st Century Kit House.
