Wondering if a two-storey extension will add value to your home? A well-planned two-storey extension can significantly increase your property's value by enhancing space and functionality. 

This guide explores how much value a two-storey extension can add, the key factors that influence property value, and tips for maximising your return on investment. Learn about popular extension ideas and how they can appeal to future buyers, boosting your home's marketability.

Will a Two-Storey Extension Add Value?

Adding a two-storey extension to your home can significantly increase its value. This type of extension not only boosts the size of your property but can also enhance its appeal to potential buyers. A two-storey extension can add extra bedrooms, bathrooms, and even open-plan living areas that modern buyers often seek. Whether you are looking to sell soon or simply want to enjoy more room, an extension can be a good investment.

Extensions, especially two-storey ones, offer more space without the need to move. In many areas, particularly in high-demand locations like London, extra space can add more value to your property. The added living space and additional rooms can make your home not only more enjoyable to live in but also more attractive to buyers when you decide to sell.

Research shows that such extensions can often provide a good return on investment. However, it’s crucial to consider your needs, budget, and local housing market trends before making any decisions. The quality of work, design, and materials used can also play a significant role in determining the added value.

Things to Consider to Add Value with an Extension

When contemplating a two-storey extension, it is crucial to ensure you have all the essential elements in place to maximise the added value to your property. First and foremost, verify if you need planning permission for your extension. 

In many instances, permitted development rights in England and Wales may apply, but it's vital to confirm this with your local council. Also, make sure your plans comply with all building regulations to avoid potential legal issues. The design and layout of your extension should integrate seamlessly with your existing house. Consulting architects or designers can help create a harmonious flow between the old and new spaces.

Open-plan designs are particularly popular and can make homes more appealing to buyers. Choose a style that complements the overall look of your property. The quality of materials you use in your extension is another crucial aspect. 

While higher-quality materials might be more expensive, they can significantly boost your home's value. Materials that are both structurally strong and aesthetically pleasing can enhance your home's appeal. Adding extra bedrooms and bathrooms can notably increase your property's value.

An additional bedroom, especially with an en suite bathroom, is often highly sought after by buyers. Moreover, incorporating additional utility spaces, like a garage or a kitchen, can further enhance your home's functionality and market appeal. Conducting market research to gauge how much value a two-storey extension could add is essential for making informed decisions. Examine properties in your area to see how extensions have increased their value.

Setting a realistic budget for your project is also important. Keep in mind the average cost of building a double-storey extension and allow for a buffer to cover unexpected expenses. Working with professionals to obtain detailed quotes can help you stay within your budget. 

Lastly, it is vital to hire reliable and reputable builders to ensure the work is completed to a high standard. Poor workmanship can detract from the potential added value of your extension. By carefully considering these factors, you can ensure your extension adds significant value to your home.

How Much Value Will A Two-Storey Extension Add?

The amount of value a two-storey extension adds to your home can depend on various factors such as location, design, and the current housing market. According to information provided by Trimble Architects, a well-executed two-storey extension can increase the value of your property by up to 20%.

For instance, adding an extra bedroom and bathroom could add significant value, especially in high-demand areas like London. On average, you may expect a return on investment that is considerably higher than the initial cost to build the extension.

However, the added value does an extension bring also depends on the quality of the work and materials used. A poorly designed or constructed extension could fail to maximise its potential value. Homeowners should aim for high-quality finishes and ensure the extension seamlessly integrates with the existing house to attract the best offers.

It is also beneficial to keep the added square footage and functionality in mind. Extensions that provide practical and appealing spaces are more likely to increase the value of your home. Before commencing any project, it’s advisable to consult with real estate experts and review local market conditions to gauge the potential value of your property.

Where On My Home Should I Add My Two-Storey Extension?

Choosing the right location on your home for a two-storey extension is essential. Several factors come into play to ensure your extension is both functional and aesthetically pleasing. Rear extensions are popular choices for homeowners looking to add valuable extra living space, such as a larger kitchen or a more expansive living area. These extensions create a more open-plan feel, which is desirable for many buyers.

Adding a two-storey extension to the side of your home can also be a great option. It can either increase the size of existing rooms or create entirely new ones. However, it's crucial to ensure this option complies with permitted development rights in your area.

Building above an existing garage is another cost-effective way to add extra bedrooms or an en suite bathroom. This type of extension makes efficient use of your home's footprint without reducing precious garden space. For those looking to significantly increase their living area, a wrap-around extension, which combines a rear and side extension, might be the best option. It’s ideal for creating a large open-plan kitchen dinner or a spacious family room. Just ensure it complements the existing layout of your house.

Although less common, a front extension can enhance the appearance of your house and add features such as a welcoming porch or extra living space. Ensure it matches the architectural style of your property to maintain a cohesive look. It’s also important to consider the neighbourhood aesthetics.

Extensions that clash with the local style can actually decrease your home’s overall appeal and value. Consulting with architects and builders can help you determine the best location for your two-storey extension. Consider the size, design, and function of the space you wish to create. Ensure that the new extension doesn’t negatively impact your neighbours, and always consider planning permission requirements.

How Long is The Process of Planning Permission for a Two-Storey Extension?

The process of obtaining planning permission for a two-storey extension can vary in length depending on several factors. On average, you can expect the process to take around 8 to 12 weeks. Start by researching whether your extension falls under permitted development rights, which allow certain types of extensions without full planning permission. However, for most two-storey extensions, you'll likely need planning permission.

Seek pre-application advice from your local council. This can offer guidance on whether your proposed extension meets planning policies. Work with an architect to draw up detailed plans that accurately illustrate your proposed extension. High-quality plans are crucial for a smooth application process.

Submit your planning application alongside all required documents and drawings. Ensure you complete the application fully to avoid delays. After submission, the council will conduct a public consultation, inviting neighbours to provide feedback. This stage usually lasts between 2 and 3 weeks.

The council will assess your application against local planning policies, site visits, and any public feedback. This is the longest stage and can take up to 8 weeks. Once assessed, the council will approve, reject, or request changes to your application. If approved, you can proceed with your project.

If rejected, you may need to alter your plans and reapply. After obtaining planning permission, you must comply with building regulations. These ensure the structural safety and environmental standards of the building. You may need to make changes to your plans based on building regulation requirements. It’s essential to understand that building regulation approval is a separate process from planning permission, and both sets of requirements must be met before construction can begin.
