Use this county hub to start local research before requesting quotes. Each county page covers the checks that tend to change by location: access, retained garden space, delivery route, services, local authority confirmation, and supplier coverage.
The national planning discussion is moving, but a county page should not be treated as permission to build. Use it to prepare better questions for suppliers and your local authority.

Important caution
Planning, building regulations, finance, insurance, and tax can all depend on the final use and site facts. Detached modular units should not be described as currently qualifying for Rent-a-Room relief. Confirm the current position with Revenue, your local authority, and qualified advisers before making a build decision.
