Permitted Development

What is Permitted Development?

You don’t always need Planning Permission to make changes and improvements to your home or property. There are many changes you can make under what is known as permitted development.

Projects such as extensions, porches, additions to the roof and outbuildings may all fall into permitted development although in most cases, building regulations will still need to be submitted.

At Wright Ruffell Cameron, we can help you to guide you through the permitted development process with advice, drawings and submissions.

Our permitted development process follows these simple steps:

Step 1: Free Local Initial Consultation
Step 2: Site Survey & Computerised Sketch Drawings
Step 3: Move Forward to Agreed Buiding Regulations Drawings
Step 4: Submit to Building Control for Approval

Types of Permitted Development Rights

Householder PD rights will fall in different categories depending on the type of work that is being planned. These are the categories:

Class A

Extensions (enlargement, improvement or alteration)

This class allows a householder to build a single-storey side extension up to half the width of the existing dwelling; a single-storey rear extension up to 4m in length for a detached dwelling and 3m long for a semi or a terrace house; and, in certain circumstances, 3m two-storey rear extensions.

There were some changes that took effect on 30th May 2019, that means larger single-storey rear extensions of up to 8m (6m for semi or terrace) are permissible under Class A, but they do require prior notification.

Class B

Additions to the roof

This allows for rear dormers and hip-to-gable extensions as long as the additional volume created does not exceed 50m3 (40m3 for semis and terraced homes).

Class C

Other alterations to the roof

Class D

Porches

Class E

Buildings etc. (outbuildings)

This allows for an outbuilding to be erected within a residential curtilage as long as it is sited behind the principal elevation, does not cover more than 50% of the curtilage and is not more than 3m in height (4m for a dual-pitched roof; 2.5m where it’s within 2m of a boundary).

There are also specific regulations relating to Hard Surfaces (Class F), Chimneys & Flues (Class G) and Microwave antennas (Class H).
