How much does a planning application cost?

Can I add bi-fold doors to my extension?

Yes, provided the extension itself complies with permitted development rules and glazing requirements meet building regulations standards.

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.

Do I need prior approval for a larger extension?
