Can I have a roof window if I live in a conservation area or listed building?
Designated areas include areas of outstanding beauty, national park, conservation area or World Heritage Sites. You must apply for planning permission before a loft conversion in a conservation area. Considerations for permission include the height of the roofline, the impact on parking, the loss of light, privacy, noise and effect on nature conservation.
If you construct a loft conversion without a planning permission, your loft conversion is illegal and attracts a hefty fine of up to £10,000.
