Frequently Asked Questions

Is there a limit on total site coverage?

Yes. Extensions and outbuildings combined must not cover more than 50% of the curtilage of the original house.

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.

Will neighbours be notified?

Under prior approval procedures or planning applications, neighbours are typically notified.

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.

What is the 45-degree rule?

The 45-degree rule is a guideline used by some councils to assess impact on neighbouring properties, particularly in relation to light and outlook.

Does permitted development apply to new-build homes?

Some new-build homes have permitted development rights removed by planning condition.
