         Building Regulations and Planning Permissions

Local Authority Control

Two main procedural option are available under the local authority system of control:

-Control based on service of a building notice. -Control based on the deposit of full plans.

Under local Permitted Developments rules,extensions of a certain volume and in specific positions, rear extensions for example,can be build using only Building Regulations approval.

There are two types of planning application: Detalied and Outline.

If you are not sure how the Council will react to the application , an Outline plan is recomended before spending time and money on an Detalied set of drawings.

Whether the new extension does or does not require planning permision, it will require Building Regulation approval.
