Ground floor extensions are a popular way to add more space to a home without the need to move to a new property. They can be used to create additional living areas, extend kitchens, add bedrooms or even create a home office. Ground floor extensions can be a great way to add value to your property as well as improving your quality of life. In this article, we will cover everything you need to know about ground floor extensions, including the different types available, planning permission, costs, and how to go about getting the work done.


Types of Ground Floor Extensions

There are several different types of ground floor extensions to choose from, each with its own advantages and disadvantages. Here are the most popular types of ground floor extensions:

Rear Extensions: This type of extension is popular because it adds additional living space to the rear of the property. Rear extensions can be single or multi-story and are usually built onto the existing structure of the house. They are often used to extend the kitchen or to create a larger living room.

Side Extensions: Side extensions are often used to create a new room or to extend an existing one. They can be single or multi-story and are built onto the side of the property. Side extensions are often used to create a new bedroom or to extend the living room.

Wrap-Around Extensions: This type of extension is a combination of both rear and side extensions. It can be a single or multi-story extension that wraps around the side and rear of the property. Wrap-around extensions can be used to create a large open-plan living space or to add additional bedrooms and bathrooms.

Planning Permission

Before you start any work on a ground floor extension, you will need to check if you need planning permission. In some cases, you may not need planning permission if your extension meets certain criteria. The criteria can vary depending on the location of the property, the size of the extension, and the type of extension you are planning to build.

In general, if your extension is less than 4m in length for a detached house or 3m for a semi-detached or terraced house, it will be considered a permitted development and will not require planning permission. If your extension is longer than these limits, you will need to apply for planning permission.

You will also need to consider the impact of your extension on your neighbours. You will need to give them notice of your plans and make sure that your extension does not affect their right to light or privacy.

Costs

The cost of a ground floor extension can vary depending on the type of extension you choose and the size of the project. We have written a separate article on how much you can expect to pay for a home extension in London and surrounding areas. You can read it here.

It’s important to remember that these costs are just estimates and can vary depending on the location of the property, the size and complexity of the project, and the materials used.

Factors that Affect the Cost of a Ground Floor Extension

There are several factors that can affect the cost of a ground floor extension, including:

Size: The size of the extension is one of the most significant factors that will affect the cost. The larger the extension, the more materials and labor will be required.

Location: The location of the property will also affect the cost of the extension. If the property is located in a city, the labor costs may be higher than in a rural area.

Materials: The materials used for the extension will also affect the cost. High-end materials, such as oak or granite, will be more expensive than more basic materials such as brick or uPVC.

Complexity: The complexity of the project will also affect the cost. If the extension requires a lot of structural work or the installation of complex features, the cost will be higher.

Timeframe: The timeframe for the project will also affect the cost. If the project needs to be completed quickly, the cost may be higher due to the need for overtime or additional labor.

How to Get a Ground Floor Extension

Getting a ground floor extension can be a daunting task, but with the right preparation and planning, it can be a straightforward process. Here are the steps you need to follow to get a ground floor extension:

Determine the type of extension you want: The first step is to decide on the type of extension you want. Consider the size of the extension, the purpose of the extension, and the style of the extension.
