Frequently Asked Questions

What is the difference between planning permission and building regulations?

Planning permission controls development impact, while building regulations ensure structural safety and compliance.

Can I extend my house in a flood zone?

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

What is retrospective planning permission?

Retrospective applications seek approval for work already carried out.

Can I build over a sewer?

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

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

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

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.
