Frequently Asked Questions

Is there a limit on total site coverage?

Yes. Extensions and outbuildings combined must not cover more than 50% of the curtilage of the original house.

Will permitted development rules change?

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

Do I need structural calculations?

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

What is the maximum size allowed under permitted development?

Size limits depend on property type and location. Detached houses may have larger rear extensions than terraced homes, subject to height and boundary constraints.

Can I add a balcony to my extension?

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

How long does a Lawful Development Certificate take?

Most councils determine applications within eight weeks, though timescales may vary.
