Frequently Asked Questions

Can I extend in a National Park?

National Parks have stricter controls and reduced permitted development rights.

Are garden rooms permitted development?

Garden rooms may qualify if they meet size and usage limits and are not used as separate accommodation.

Can I convert my garage into living space?

Garage conversions are often permitted development, but planning restrictions may apply depending on conditions attached to the original approval.

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 build right up to my boundary?

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

What is the difference between planning permission and building regulations?

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