Frequently Asked Questions

Basement development may require planning permission, especially if it alters the external appearance.

Are there restrictions on side-facing windows?

Can I convert my loft and add a dormer?

Dormer loft conversions are often permitted development within volume limits.

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.

Does building regulations approval still apply?
