Frequently Asked Questions

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 onto agricultural land?

Residential permitted development rights apply only within the residential curtilage.

Do I need planning permission for a rear extension in Keysoe?

Many rear extensions fall within permitted development limits, but projection depth, height, and boundary proximity must comply with national rules and any local restrictions.

Can I add a balcony to my extension?

Balconies and raised platforms are not permitted development and usually require planning permission.

Can I build right up to my boundary?

It depends on height and location. Boundary proximity affects allowable eaves height.

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.
