Frequently Asked Questions

Can I build over a sewer?

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

What is the maximum size allowed under permitted development?

Size limits depend on property type and location. Detached houses may have larger rear extensions than terraced homes, subject to height and boundary constraints.

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 appeal a planning refusal?

Yes. Applicants may appeal to the Planning Inspectorate within specified time limits.

Can I extend a semi-detached house differently to a detached house?

Yes, size limits and projection distances differ depending on property type.
