The case studies showcase the range of delivery routes to custom and self build. They represent developments in a mix of sizes (0-10 units, 11-50 and 51+) in both urban and rural settings. They include exemplars of other elements, such as private- and public-led examples, as well as joint projects, and also international and community-led developments. Finally, they illustrate some of the types and models, for example ‘shell’, dense solutions such as terraces or apartments, or sites with a mix of house types. Together these reflect the spectrum that is custom and self build.
