Frequently Asked Questions

How is the original house defined for measurement purposes?

The “original house” refers to the property as it stood on 1 July 1948 or when it was first built, not including later extensions.

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.

Can I convert my garage into living space?

Garage conversions are often permitted development, but planning restrictions may apply depending on conditions attached to the original approval.

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.

Can I add bi-fold doors to my extension?

Yes, provided the extension itself complies with permitted development rules and glazing requirements meet building regulations standards.

Can I submit planning drawings myself?

Yes, but professional plans improve clarity and reduce refusal risk.
