When permitted development may apply
Permitted development rights allow certain types of household building work without a full planning application. They are subject to detailed limits covering matters such as height, depth, position and materials.
- The property must retain the relevant permitted development rights.
- The proposal must remain within the current dimensional limits.
- Listed buildings, flats and some designated areas are treated differently.
When an application is likely
An application may be required where the design exceeds permitted development limits, changes the principal elevation, affects a protected building or sits within an area with additional controls.
A clear measured survey and accurate proposed drawings make it easier to test the design against the relevant rules before committing to the next stage.
A sensible first step
Start by confirming the planning history, local constraints and the type of approval the project is likely to need. Where permitted development is being relied upon, a lawful development certificate can provide useful formal confirmation.
