Mandating self-build and custom housing plots in larger developments seems appealing in theory, but the execution could prove chaotic. Many aspiring self-builders may lack the experience and support to complete their ambitions, especially amidst complicated regulations. Adding more pressure on local planning institutions that are already struggling with significant workloads could compromise their effectiveness. Ensuring that these plots are suitable and properly marketed adds yet another layer of frustration to a process that should be welcoming and inclusive. The plan could benefit from measures that afford more support and guidance to potential self-builders, rather than relying largely on self-governance.
