Frequently Asked Questions

Does permitted development apply to new-build homes?

Some new-build homes have permitted development rights removed by planning condition.

Does an Article 4 Direction affect my extension plans?

Yes. Article 4 Directions remove certain permitted development rights, meaning planning permission may be required.

Can I appeal a planning refusal?

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

Does permitted development apply to HMOs?

Some permitted development rights may be restricted depending on property use class.

Can I build a two-storey extension without planning permission?

Two-storey extensions are sometimes permitted, but stricter limits apply to height, rear projection distance, and window placement to avoid overlooking neighbours.

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.
