Permitted Development Classes

Comprehensive guide to all GPDO classes for residential properties

Understanding GPDO Classes

Always Verify Your Circumstances

These class definitions provide general guidance. Your specific property may have additional restrictions due to conservation areas, Article 4 Directions, listed building status, or conditions on previous planning permissions. Always check with your local planning authority before proceeding with any development.
