Frequently Asked Questions

Can I extend my house in a flood zone?

Extensions in flood risk areas may require additional assessments and possibly planning permission.

Does an Article 4 Direction affect my extension plans?

Yes. Article 4 Directions remove certain permitted development rights, meaning planning permission may be required.

Are there restrictions on side-facing windows?

Yes. Upper-floor side-facing windows typically must be obscure-glazed and non-opening below a certain height.

Are basements covered by permitted development?

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

Can I build over a sewer?

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

Can I extend a flat under permitted development?

Flats and maisonettes generally do not benefit from permitted development rights for extensions.
