What Is a Garden Room? Cost, Value & Planning Rules
Introduction
If you’re looking to expand your living space without the hassle of a full home renovation, a garden room could be the perfect solution. In this blog, we’ll explore what a garden room is, how it can add value to your property, the costs involved, and whether planning permission is required. By the end, you’ll have all the information you need to decide if a garden room is right for you.
What is a Garden Room?
A garden room is a versatile, standalone structure typically installed in your backyard or garden. Unlike conservatories or extensions, garden rooms are built to provide versatile spaces for various uses. Our garden rooms are crafted from high-quality materials like aluminium and glass, offering a modern aesthetic while seamlessly blending with natural surroundings. However, they may not provide the same level of insulation as other options, making them ideal for seasonal or occasional use.
Garden rooms are highly customisable and can serve a variety of purposes, such as:
- A home office or studio
- A gym or wellness space
- A playroom for kids
- A guest suite
- A hobby or craft room
With modern designs and eco-friendly construction options, garden rooms are an attractive and functional addition to any outdoor space. Learn more about the various Garden Room Ideas our previous clients have created to enhance their outdoor living.
Differences Between an AGV Garden Room & a Conservatory
While both garden rooms and conservatories offer additional living space, they differ in design, functionality, and usage. Here are the main distinctions:
- Structure and Materials: Conservatories are primarily constructed with large glass panels and a minimal frame, while AGV garden rooms often incorporate aluminium, glass, and other materials for a more solid, modern look.
- Insulation: Conservatories tend to lack insulation, making them less suitable for year-round use, whereas garden rooms, while not always highly insulated, can offer better seasonal comfort depending on design.
- Functionality: Conservatories are generally used as transitional spaces between indoors and outdoors, often functioning as sunrooms. Garden rooms, on the other hand, are standalone, versatile spaces designed for specific purposes like offices, gyms, or guest accommodations.
- Planning Permission: Conservatories are more likely to require planning permission, especially if they alter the primary structure of the house, while many garden rooms fall under Permitted Development rights.
Choosing between a conservatory and a garden room largely depends on your needs, aesthetic preferences, and how you intend to use the space.
Does a Garden Room add value to your Property?
The short answer is yes – a garden room can increase the value of your property. Here’s why:
- Additional Usable Space: A garden room provides extra square footage, which is always appealing to potential buyers. Whether used as a home office or a relaxation retreat, the added space is a valuable asset.
- Modern Appeal: A sleek, well-designed garden room can make your property stand out in the market. Buyers are increasingly drawn to flexible spaces that cater to remote work and lifestyle needs.
- Cost-Effective Alternative: Compared to traditional extensions, garden rooms are a more affordable way to add functional space, which boosts your property’s overall appeal.
While the exact value added depends on factors like size, design, and location, some estimates suggest that a high-quality garden room can increase your home’s value by up to 5-10%.
How Much Do Garden Rooms Cost?
The cost of a garden room can vary widely depending on its size, materials, and level of customisation. Here’s a breakdown of typical price ranges:
- Basic Models: Starting at around £6,500 to £10,000, these are small, simple structures with minimal customisation.
- Mid-Range Options: For £15,000 to £25,000, you can get a larger, insulated garden room with features like electricity, heating, and higher-quality finishes.
- High-End Designs: Premium garden rooms can cost upwards of £25,000 to £40,000 or more. These are bespoke, luxury spaces with top-tier materials, integrated technology, and sophisticated designs. Depending on your needs, this model may include features such as screening, an awning, or even a bespoke kitchen for a truly personalised touch.
It’s important to factor in additional costs, such as foundation work, utilities (electricity and plumbing), and any required landscaping to prepare the site.
Do Garden Rooms Need Planning Permission?
In many cases, garden rooms fall under Permitted Development rights, meaning you don’t need formal planning permission. However, there are specific conditions to keep in mind:
- Size and Height: The structure must not exceed 2.5 meters in height if it’s within 2 meters of a boundary. If further away, the height limit is 4 meters for a dual-pitched roof or 3 meters for other roof types.
- Usage: The garden room must be ancillary to the main house. Using it as a permanent living space, such as a self-contained apartment, may require planning permission.
- Location: If your property is in a conservation area, a listed building, or a national park, additional restrictions may apply.
It’s always a good idea to consult your local planning authority to ensure compliance with regulations.
Conclusion
A garden room is a fantastic way to enhance your home, offering additional space, versatility, and aesthetic appeal.
With careful planning, budget considerations, and adherence to planning regulations, a garden room could be the perfect investment for your home and lifestyle.

Important Factors to Consider
When planning your garden room, keep the following design aspects in mind:
- Purpose and Layout – Determine how you’ll use the space to guide the design. For instance, a home office might require built-in desks and ample lighting, while an entertainment room might need wiring for sound systems.

- Insulation and Heating – Ensure your garden room is well-insulated and consider options like wall mounted heating to keep it cozy.
- Planning Permissions – Most garden rooms fall under permitted development rights, but it’s essential to verify local regulations, especially for larger or attached structures.
- Aesthetic Integration – Match the design of your garden room to your home’s architecture and garden style for a cohesive look.
Getting Started with Your Garden Room Extension
