Frequently Asked Questions

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.

What measurements are used for height?

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

Do conservation areas affect permitted development rights?

Yes. Properties within conservation areas often have additional restrictions, and some permitted development rights may be limited or removed entirely.

Can I appeal a planning refusal?

Yes. Applicants may appeal to the Planning Inspectorate within specified time limits.

Can I build a wraparound extension without planning permission?

Wraparound extensions often exceed permitted development limits and usually require planning approval.
