Building

17 Feb 23

Extending your home in London can be an excellent way to add valuable living space and increase the value of your property. However, before you begin your home extension project, it is important to understand the planning permission process in London. In this article, we will explore the planning permission requirements for home extensions in London and what you need to know to ensure that your project is legal and approved.


What is Planning Permission?

Planning permission is the legal process that homeowners must follow before starting any building work on their property. It is a set of rules and regulations that ensure that any changes to a property are safe, sustainable, and in keeping with the surrounding area.

In general, planning permission is required for any building work that involves an extension that is more than 50% of the original size of the house or more than 4 metres in height. However, this can vary depending on the location of the property, the size of the extension, and other factors.

Planning Permission Requirements in London

In London, planning permission requirements can be more complex and stringent than in other parts of the UK. This is because London is a densely populated area with a unique set of challenges and considerations.

The London Plan is a document that sets out the strategic planning guidelines for London. It provides a framework for the development of the city and includes policies on issues such as housing, transportation, and the environment. It also includes policies on home extensions and planning permission requirements.

In general, planning permission for home extensions in London will depend on factors such as:

The Size of the Extension

The size of the extension is one of the most important factors in determining whether planning permission is required. In general, planning permission is required for any extension that is more than 50% of the original size of the house or more than 4 metres in height.

The Location of the Property

The location of the property is also an important factor in determining whether planning permission is required. Properties that are located in conservation areas or are listed buildings may require special permission before any building work can be carried out.

The Impact on Neighbours

The impact on neighbours is another important factor to consider when applying for planning permission. Extensions that will impact the privacy, light or views of neighbouring properties may require additional consideration and consultation with neighbours.

The Impact on the Environment

The impact on the environment is another factor that is taken into account when applying for planning permission. Extensions that will have a significant impact on the environment, such as those that affect trees or watercourses, may require additional consideration and consultation with local authorities.

How to Apply for Planning Permission

If planning permission is required for your home extension project, you will need to apply to your local planning authority. In London, this is typically your local borough council. You will need to provide detailed plans of the proposed extension and demonstrate that the project meets all the necessary requirements and guidelines.

In general, the planning permission process can take up to eight weeks, although more complex projects may take longer. It is important to ensure that you allow plenty of time for the planning permission process, as any building work carried out without permission can result in legal action and costly fines.


Conclusion

Extending your home in London can be an excellent way to add valuable living space and increase the value of your property. However, before you begin any building work, it is important to understand the planning permission requirements in London.

In general, planning permission is required for any extension that is more than 50% of the original size of the house or more than 4 metres in height. However, this can vary depending on the location of the property, the size of the extension, and other factors.

By working with an experienced and reputable builder, you can ensure that your home extension project meets all the necessary planning permission requirements and guidelines. They will be able to provide you with advice on the process and help you to complete the application process.

Additionally, it is important to involve your neighbours in the planning permission process. This can help to avoid any potential disputes or objections and can make the process smoother and quicker. By communicating with your neighbours and consulting them on your plans, you can ensure that your project is well-received and accepted by the community.

In summary, planning permission for home extensions in London is a complex and important process that should not be overlooked. It is essential to understand the requirements and guidelines for your particular location and project, and to allow plenty of time for the application process.
