Can I build a dwelling in my back garden?

Commonly known as backland development, many older homes especially, have large mature plots that are underused in terms of building intensity, or are located on generous corner plots. There are some instances where there are a row of terraced homes which together could provide development opportunity if there is vehicular access. This could be beside a property, via a shared driveway or track.

In the past planning authorities considered this kind of development as 'over development', and planning permission was often rejected.

However with the pressure to provide more housing, under the guidance held within the National Planning Policy Framework they have become more flexible under certain circumstances.

Vehicular access is usually the key.

A plus point in obtaining planning permission for your new dwelling(s) is to have some sort of access. This could be:

✔️ Direct road frontage

✔️ Access could be obtained through a boundary fence or hedge

✔️ Access via some kind of track or pathway

The second plus point would be if you actually owned the access.

The local authority will also be looking for:

✔️ Adequate parking provision for the existing property and new dwelling

✔️ There must be access for emergency services

Access for emergency services is pretty crucial unless the property is at the end of a quiet close.

What should be considered?

With this type of development, it is important to consider your surroundings, your neighbours and the impact your new build will have on the area.

If your new dwelling removes parking spaces or it involves the removal of mature trees you will have to pay special attention to providing additional spaces and replant trees within your proposal.

With this type of development, to win over planning authorities you should consider building a property that fits aesthetically within the street scene. However, this varies from authority to authority. Some prefer a contrast to existing properties. Avoiding an unsightly infill will usually improve your chances of obtaining planning.

Provision for drainage and waste

Your new property will have to be connected to all services, so this should be a part of your planning application.
