Permitted development is not automatic
Rights can be restricted by the type of property, previous extensions, designated areas, planning conditions and other factors. Flats and maisonettes are treated differently from houses.
Building Regulations are separate
Planning permission and Building Regulations are different systems. An extension that does not require planning permission can still require Building Regulations approval.
Party Wall matters may also apply
Work close to a neighbour, on a shared wall or involving certain excavations may bring the Party Wall etc. Act 1996 into consideration. Specialist advice may be appropriate.
Check before building
Use your local planning authority and the Planning Portal for current guidance, and confirm responsibility for drawings, structural calculations and approvals before construction begins.
