A wrap-around extension, sometimes known as an L-shaped extension, is a form of expansion that extends the house back and to the sides in an L formation around the current building, giving the final result width and depth.

Wrap-around extensions also allow for a wider range of design choices and the ability to bring more natural light into your home while also better connecting you with your garden.

The house extension process

When planning a house extension, it’s important to be aware of the process involved. This will help you understand what is required and ensure that your project runs as smoothly as possible.

  1. The first step is to get your design, construction plans and a building specification. You also need to find out if you need planning permission or (most likely) if you can apply for Permitted Development (guidelines below).
  2. Once you have received planning permission (or confirmation that your extension qualifies for permitted development), it’s time to start work on the project. You will need to appoint a builder who will be responsible for the construction work.
  3. Once the extension is completed, you will need to apply for a building regulation certificate. This is to ensure that the work has been carried out to the required standards.
  4. Finally, once everything is complete, you can enjoy your new house extension! Just remember to keep on top of maintenance and repairs to ensure that your extension remains in good condition.

By following these steps, you can be sure that your house extension project will run smoothly from start to finish. So if you’re thinking about extending your home, don’t hesitate to contact us – it could be the best decision you ever make!

Frequently asked questions

You can expect a house extension to add between 5-20% depending on the type and size of the extension and the location on the property.

While there is no definitive answer, there are a few things you can do to increase the value of your home.

  • Firstly, make sure your extension is designed and built to high standards. This will not only increase the value of your home but will also make it more attractive to buyers if you decide to sell in the future.
  • Secondly, think about what type of extension you want. A single-storey extension is generally the most popular and can add up to 8% in value to your property. If you have the space, a two-storey extension can be even more valuable.
  • Finally, consult with an experienced architect or builder who can give you tailored advice on the best way to add value to your home. By following these tips, you can ensure that your house extension not only adds extra space and functionality to your home but also increases its overall value.

The cost of extending an existing property is not always straightforward. In order to get accurate house extension costs, it is important to seek the advice of a professional builder or house extension specialist.

There are many variables that can affect the cost of extending a property, such as the size and complexity of the project, the type of materials used, and the location of the property.

We will give you a detailed cost after we visit the property and get a clear understanding of your requirements.

If you’re thinking about extending your home, one of the first things you’ll need to consider is planning permission. In many cases, you will not need to apply for planning permission as it will fall under Permitted Development rules.

It is very likely that you can build your house extension under Permitted Development (PD) if your project adheres to the following criteria:

  • You may add 8m to the rear of a detached house if it is a single-storey extension (6m for a semi or terraced house), or 3m if it is double.
  • Any single-storey extension must not exceed 4m on the ridge and the eaves, and ridge heights of any extension cannot exceed the existing property.
  • Two-storey extension, it must not be closer than 7m to the rear boundary.
  • Side extensions must be single-storey and have a maximum height of 4m and a width less than half of the original building.
  • Any additional building must be constructed in the same or comparable material as the existing house.
  • Extensions must not extend beyond the building line of the original dwelling.
  • Side extensions require planning permission and all rear extensions must be single-story in areas (such as areas of outstanding natural beauty, conservation sites, etc).
  • The extension must not cover more than half of the garden.

You can read the Permitted Development rights for householders’ technical guide for further detail.

When planning a house extension, it’s important to think about the design of the extension and how it will integrate with the existing house.

Some things to consider include:

the size of the extension – how big should it be? Will it overpower the existing house or be in proportion?

the style of the extension – will it match the existing house or be a different style?

the layout of the extension – how will it fit in with the existing house? Will it be an open plan or separate rooms?

the materials used – what will the extension be made from? Will it match the existing house?

These are just a few things to think about when planning a house extension. By taking into account these considerations, you can ensure that the finished extension looks good and is perfectly integrated with the existing house.

You have a number of options available when it comes to designing your house extensions:

  • architects
  • architectural technicians
  • specialist designers
  • package build companies’ in-house design teams

You can leverage your construction company’s experience and ask them to recommend someone that had worked on similar projects.

Building regulations apply to all extensions, even those that qualify under Permitted Development Rights.

Building regulations are in place to ensure that all construction work is carried out to a safe standard.

There are minimum requirements set out by building regulations for:

  • structural integrity
  • fire safety
  • energy efficiency
  • damp proofing
  • ventilation
  • and other key aspects that ensure a building is safe.

The regulations cover a wide range of issues, such as the use of materials, fire safety, insulation and ventilation. It’s important that your building company comply with all the relevant regulations to avoid any problems further down the line.

Building regulation certificates must be obtained once the extension is complete, in order to show that the work has been carried out to the correct standard.

If you’re going to dig or build foundations within 3m of the property line, a party wall structure, or digging foundations inside 6m of a property line, your work will need to follow the Party Wall Act. You may want advice in these situations from a surveyor.

Neighbours can’t prevent you from building to or on your property line (if you have the planning permission to do so and there aren’t any restrictive arrangements)

Adding a house extension will create more demands on the current hot water and heating system and could result in problems. If the extension has been installed it should have been properly heated, factor in your heating efficiency. The boiler size and the radiator size are also a consideration; the temperature and the reheating time will vary.

Before embarking on a property extension it is necessary for the homeowner to determine whether the Community Infrastructure Levy (CILD) is payable. The scheme may exist in certain councils and applies in areas that exceed 100 m2 of gross internal area (even in areas that are built under Permits of development).

Unfortunately, it’s far more difficult than most would think. Typically, new constructions require the builder/developer’s permission to be expanded beyond 5-10-20 years of age. This is due in large part to the builder and documentation, but it’s typical in most new homes. Planning rights are also almost always different.

You should make sure that you get written consent from the builder before starting any work. They may have specific instructions on how to extend a new build house without compromising its structural integrity.

When extending a new build house, it’s important to make sure that you use the same type of materials as the original build. This will help to maintain the warranty on the property and avoid any problems with water ingress in the future.
