Self-build
Self-build and custom-build housing is where you have primary input into the design and layout of your new home. Planning, Building Regulations and, in England, CIL self-build relief can all be relevant.
Local authorities keep registers of people seeking self-build plots.
Registers and reliefs are strongest in England; other nations support self-build through their own planning policies.
