In architecture, perhaps the most remarkable change heralded by the 20th was the radical rethinking of housing provision which it brought, driven by a worldwide population explosion and the devastation of two world wars. Of course, Modernism’s reappraisal of the design and construction of housing was one part of this trajectory, but still Modernism was underpinned by a traditional process, needing clients, designers and contractors. Arguably more radical were a small number of fringe developments, such as mail-order houses in the US and Walter Segal’s DIY home designs in the UK. These initiatives sought to turn the traditional construction process on its head, empowering people to construct their own homes by providing materials and designs as cheaply as possible.
In the 21st century, the spirit of these fringe movements is alive and well, but the parameters have changed somewhat: with a rise in individualism, and new technologies sparking the “maker movement,” the focus has shifted away from providing people with the materials to construct a fixed design, and towards improving access to intellectual property, allowing more people to take advantage of cheap and effective designs. The past decade has seen a number of initiatives aimed at spreading open source architectural design--read on to find out about five of them.
