Manufacturing in the rain
Despite the inherent difficulties and inefficiencies, more than 94% of new homes still are manufactured largely on the building site. It's as if a certain amount of suffering is the fair penance for the blessing of the product.
From experience, I know it's hard to do good work when you can't feel your fingers, or when you're ankle deep in mud, or when it's been raining for five days straight and you're spending most of your time tying down tarps. Of course, there are perfect days and perfect sites, but rarely do they come together to allow even the best crew to do optimal work. In the end, it's just plain hard to provide value to the homeowner when good work and good progress are stymied by the challenges of just being on site.
Two hundred years ago, there was no alternative. The ideas, technologies, and processes of higher-quality production hadn't been invented yet. But it wasn't so bad. Homes basically were built with stone, brick, wood, and plaster, and the work could be done by a few dedicated crews with no interruptions.
hat's not true today. Homes are now full of equipment, systems, fixtures, and materials that can require 20 or more subcontracting companies to build a single house. With all those people plying all those trades to cut, shape, and fit raw commodities into finished products on individual building sites, in all kinds of weather, our time-honored approach finally looks absurd. As Kent Larson of MIT's Open Source Building Alliance says, "Building homes entirely on site now makes as much sense as building a car in your driveway."
