Building regulation plans outlines the specification to which your building project should be constructed to. Your project manager and builder will use these building regulation plans almost like instructions for the construction of your new extension or new home.
You can generally jump straight to having building regulation plans drawn up if you have permitted development rights on your property. If you do not have permitted development rights you will need to apply for planning consent before building regulations are required.
So your building regulation plans have been approved and you're ready to go.
When you start building a building inspector will carry out checks at certain phases of the build. These checks are to help ensure your builder is building your project to the standard of current building regulations. Once your project is complete your building inspector will complete a final check and provide you with completion certificate.
We have mentioned Permitted development rights a couple of times here on 1MoreRoom.co.uk if you would like more information on the subject please use the link below to the governments planning portal.
