Many householder extensions and alterations in England can be carried out under permitted development rights in Schedule 2, Part 1 of the Town and Country Planning (General Permitted Development) (England) Order 2015, subject to limits and conditions. Some need prior approval.
Who it is for
It is written for homeowners, designers and small builders working on house extensions and loft conversions in England, to check the planning route and keep building control steps on track. It does not replace advice from your local authority.
How to use it
Answer each Yes/No question. In Excel the next question and the result appear automatically. The Word version has numbered questions with go-to instructions. Each route ends at within permitted development limits, prior approval needed, or planning permission needed. Every question cites the paragraph it comes from.
