Rules & recordWhat a conservation area changes
Extensions
Side extensions, and rear extensions of more than one storey, are not permitted development — they need planning permission. Single-storey rear extensions keep their normal limits, but the Larger Home Extension prior-approval route is not available.
Lofts and roofs
Roof extensions such as dormers are not permitted development. Rooflights are usually fine if they don't project more than 15 cm.
Cladding
Cladding the outside of a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles needs planning permission.
Outbuildings
Garden rooms, sheds and other outbuildings to the side of the house need planning permission.
Demolition
Demolishing a building larger than 115 m³ needs planning permission. Taking down a wall, gate or fence over 1 m high next to a road (or 2 m elsewhere) also needs permission.
Trees
You must give the council six weeks' notice before cutting down or pruning most trees (trunk over 7.5 cm across at 1.5 m high), even if they are not protected by a tree preservation order.
Article 4 directions
Councils can remove more permitted development rights — for example for windows, doors, porches or front boundaries — with an Article 4 direction. Check the council's list below.
