When permitted development is likely to apply, when it won't, and what to check before you spend money on drawings.
Permitted development
Many single-storey rear extensions can be built under permitted development rights, subject to limits on depth, height and how much of the garden is covered. Those rights can be removed — by an earlier planning condition, by an Article 4 direction, or because the property is a flat or listed building.
When you'll need an application
Two-storey extensions, work to the front of the property, work in a conservation area and anything exceeding permitted development limits will normally require a full householder application.
Building regulations are separate
Planning and building regulations are different processes. Even where planning isn't required, the work still has to be designed and built to meet building regulations and be signed off by building control.
