The Side Return Extension Guide 2024

Looking to add some extra living space to your home, but worried about sacrificing your precious garden? Side return extensions might be the perfect solution! This type of extension is particularly popular for homeowners in terraced or semi-detached houses.

In fact, if you live in an English home built between the 19th and early 20th century, there's a good chance you already have a similar extension at the back of your house – those classic brick additions! Side return extensions take a different approach, utilizing the often-unused narrow strip of land that runs alongside the ground floor of your home. By filling in this space, you gain valuable square footage without significantly shrinking your garden. It's a win-win, especially in urban areas where space is a premium.

This guide will be your one-stop shop for all things side return extensions. We'll cover everything you need to know, from the benefits they offer to the different types available.

What is a side return extension?

Imagine the narrow strip of land that runs alongside the ground floor of your house. Often used for storage or forgotten about entirely, this space is prime real estate for a side return extension. Simply put, a side return extension is an addition built onto this unused area, effectively filling the gap between your house and the side boundary. While it might seem like a small gain from the outside, it can significantly open up the interior layout and create a more spacious feel.

Benefits of a side return extension

• Maximizes space: Gain valuable square footage without sacrificing significant garden area.
• Improves layout: Creates a more open and functional living space, perfect for kitchens and dining areas.
• Better use of unused space: Transforms an underutilized area into a valuable part of your home.

Choosing the right type:

Side return extensions come in two main options:

• Single storey extension: A more affordable choice, often used for kitchen extensions.
• Double storey extension: Offers more additional space but comes at a higher cost.

Unlocking your home's potential:

With a well-designed side return extension, you can enjoy a brighter, bigger, and more functional living space.

How much does it cost to build a side return extension?

While a side return extension is generally considered a more budget-friendly option compared to other extensions, the exact cost can vary depending on several factors:

• Size: The larger the extension (square metres), the higher the overall cost.
• Location: Building costs tend to be higher in London and the South East compared to other regions in the UK.
• Materials: High-end finishes, bespoke elements, and large expanses of glass will increase the cost. Opting for standard materials and readily available options can help with budgeting.
• Complexity of the build: Any additional features like underfloor heating, complex roof structures, or major plumbing alterations will add to the overall cost.
• Architect and builder fees: Hiring an architect can add value through design expertise and navigating permission for a side return extension. Builder fees will vary depending on their experience and workload.

Here's a breakdown to help you estimate the cost:

• Single storey extension (average): £1500 - £2500 per square metre (excluding architect and builder fees)
• Double storey extension: Expect to pay significantly more than a single storey due to the additional structure and potential foundation work required.

Cost-saving tips for your side return extension

• Single storey vs. double storey: While a double storey offers more space, a single storey is generally more affordable.
• Minimize built-in units: Opt for standard kitchen cabinets rather than bespoke options. Similarly, consider open shelving for some storage instead of additional units.
• Smart window choices: Large expanses of glass can be beautiful but expensive. Strategically placed windows can provide ample light without breaking the bank.
• Phased approach: If budget allows, consider completing certain elements like lighting fixtures at a later date.
• Shop around: Get quotes from several reputable builders to compare prices.

Remember, these are just estimates. Consulting with a local architect or builder familiar with current costs in your area will give you a more accurate picture of what your side return extension might cost.

Will you need Planning Permission?

In most cases, you won't need planning permission for a single-storey side return extension on a freehold property in the UK. This is thanks to permitted development rules. However, there are limitations to keep in mind:

• Height: The extension can't be higher than 4 metres.
• Width: The extension can't be wider than half the width of your original house.
• Distance to boundary: If the extension is within 2 metres of your boundary, the eaves (the overhanging edge of the roof) can't be higher than 3 metres.
• Materials: The materials used on the outside of your extension should be similar to those already on your house.

Here's when you should definitely check with your local council about planning permission:

• You live in a Conservation Area or an Area of Outstanding Natural Beauty (AONB).
• Your house is a listed building.
• There's an Article 4 direction on your property (this is a special rule that can restrict permitted development rights in certain areas).

It's always best to check with your local authority planning department to be completely sure about the regulations that apply to your specific property and project. They can advise you if you need to submit a planning application and can answer any questions you may have.

How can you bring light into the depths of a side return extension?

A major perk of side return extensions? They can flood your home with natural light! Here's how to maximize it:

• Light from above: Skylights are perfect for single-storey brick extensions, letting sunshine pour in.
• All-glass roof: This option is stunning, especially if you have tall trees nearby. Plus, the open sky view makes the space feel bigger and more connected to the outdoors.

Light reflection tricks:

• Pale color scheme: Light bounces off pale colors like white or light gray, keeping your extension bright.
• Reflective surfaces: Opt for high-gloss materials or reflective tiles to help light dance around the space.

Bringing in light from the garden:

• Strategic windows: If your extension darkens the middle of your house, consider bi-fold or sliding doors. Floor-to-ceiling windows facing the garden are another great way to usher in light.

What are the potential Party Wall issues?

The Party Wall Act of 1996 might come into play for your side return extension. This law protects both you and your neighbors by setting guidelines for working near shared walls and boundaries.

Here's what it means for you:

• Protects existing structures: If your extension work could weaken a shared wall, the Act ensures you'll fix any damage caused by your project.
• Prevents disputes: The Act outlines a process for communication and resolving disagreements with your neighbors about the construction.
• Not always needed: You might not need to involve the Party Wall Act if your extension doesn't affect any shared walls or boundaries.

Best to check: It's always wise to consult your local authority to see if the Party Wall Act applies to your specific project. This will help avoid any potential issues with your neighbors down the line.
