Permitted Development Rights – Planning a Rear Extension

Permitted Development Rights - Planning a Rear Extension

A permitted development right allows you to add a structure to your property without seeking planning permission. The height of the extension must not exceed 4 meters, and it must not take up more than half of your garden. Moreover, the extension must not be larger than three meters wide. If you are planning a rear extension, there are additional restrictions to consider.

Before building a house extension ideas structure, you need to decide if you’re going to change the use of the land. You must consider whether the change is a material one. If the change is material and significant, then you’ll need planning permission.

Restrictions apply to permitted development rights

In order to build an extension without planning permission, you must comply with certain guidelines. If you have a terraced house, you can only build a small extension, not more than 40 square meters. On the other hand, if you have a detached house, you can build a much larger extension. However, you must take into account existing roof extensions and loft conversions, as these will eat into your available cubic marriage.

Permitted development rights are laws that allow you to carry out certain kinds of work on your property without getting planning permission. They were introduced in May 2013 and made permanent by Parliament. The most recent changes to the rules increase the size limits for single-storey domestic extensions, from 4m to 8m for detached houses and from 3m to 6m for other houses. Permitted development rights are valid for up to three years, and are very beneficial for those who want to extend their property without planning permission.

Permitted development rights allow you to build extensions up to three meters from the original house and up to seven meters from the rear boundary. The only restrictions are the materials you choose for the extension and whether or not the extension will blend in with the original house. Two storey extensions are not permitted and require planning permission. In addition, any windows on the upper floor must be obscure glazing or non-opening.

Restrictions apply to single-storey rear extensions

When it comes to building a single-storey rear extension, it’s important to understand the restrictions involved in the process. Without planning permission, you’re restricted to the height of the extension and its eaves. This is the case whether you’re building a detached or semi-detached house, as well as for extensions on the side of the house. The eaves on single-storey extensions cannot be more than 3 meters above the rear wall of the original building. In addition, you cannot build a side extension that extends more than half the width of the original building.

Until recently, if you wanted to extend your home without planning permission, you’d have to get permission from the local authority. However, the good news is that the Government has relaxed some of these restrictions. Until now, you’ve had to pay an up-front planning fee to get permission to extend. In addition, planning approval can take months to be granted. While the new rules have made it easier for homeowners to extend their property, they’re still subject to building regulations and health and safety standards. If you’re planning a large extension, you’ll have to notify the local planning authority and consult your neighbors.


Single-storey rear extensions without planning permission are possible, but they should be considered carefully. You should also take into account the location of the extension. A rear extension can’t be longer than three meters and can’t face the road. The same rules apply to side extensions, but they’re generally not permitted if they’re facing a road.
