Frequently Asked Questions

What is the maximum rear projection allowed?

Detached houses may extend up to four metres under standard rules, or eight metres with prior approval. Smaller limits apply to other house types.

Can I build over a sewer?

Building near or over a public sewer may require a build-over agreement from the relevant water authority.

Do I need prior approval for a larger extension?

In some cases, larger home extensions require a prior approval process where neighbours are notified and the council assesses certain impacts.

What is the difference between planning permission and building regulations?

Planning permission controls development impact, while building regulations ensure structural safety and compliance.

What happens if permitted development rights have been removed?

If rights have been removed by planning condition or Article 4 Direction, you will likely need to submit a full planning application before building.

Do I need planning permission for a loft conversion?

Many loft conversions are permitted development, but dormer size, roof alterations, and conservation area status may affect eligibility.
