Frequently Asked Questions

Do I need structural calculations?

Yes, building regulations often require structural calculations for beams, foundations, and load-bearing elements.

Will permitted development rules change?

Planning legislation can change over time, so it is important to check current regulations.

Can I add a balcony to my extension?

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

What measurements are used for height?

Height is typically measured from the highest ground level adjacent to the building.

Can I build right up to my boundary?

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

Can I extend in a National Park?

National Parks have stricter controls and reduced permitted development rights.
