Do you Need Planning Permission for a Garden Office?
In most cases, garden offices don’t require planning permission. Thanks to permitted development rules, you can usually build without dealing with the local council, so long as your office meets size, height, and placement limits.
You may need permission if your garden office is over 2.5m high, placed in a front garden, used full-time as a business premises, or if your property is listed or in a conservation area.
Wondering if you need planning permission? You can always speak to a member of our friendly team who will be happy to answer all of your garden office questions.

Garden Office Ideas
Garden Office Pods
Garden office pods are standalone structures that provide workspaces for hybrid and remote workers. Their compact, pod-like design makes them ideal for smaller gardens, offering a modern and efficient office space. These garden rooms provide a functional workspace in your outdoor area, making them a cost-effective alternative to traditional home extensions. With their sleek and contemporary style, office pods are perfect for those seeking a quiet, separate environment to work from home.
Insulated Garden Offices
Looking for a comfortable, energy-efficient home office? Our insulated garden offices feature double glazing, heating, and fully insulated walls, roof, and flooring, ensuring warmth and productivity year-round. Whether it’s hot or cold outside, you can work comfortably in these garden rooms. Designed to meet all your needs, they offer an ideal solution for creating a home office that combines comfort, efficiency, and a perfect work environment throughout every season.
Small Garden Offices
Small garden offices are a practical solution that transforms compact spaces into cosy, functional areas. In the UK, where the average garden size is just 255 m², many homeowners struggle with limited space for home extensions. However, small garden rooms provide an ideal remedy, offering a dedicated workspace without encroaching on valuable outdoor space. Designed for year-round use, these offices create a professional environment and often require little to no planning permission, making them a hassle-free addition to your home.
Cheap Garden Offices
Our affordable garden offices start at just £9,995, providing a cost-effective and practical solution to expand your space without sacrificing quality. Whether you’re looking for an office studio, creative space, or functional office pod, we offer a range of garden rooms to suit your budget and lifestyle.

Garden Office FAQs
Garden offices are insulated like houses, using the same materials and techniques as modern home construction. They feature smart, breathable insulation that regulates temperature, keeping the space warm in winter and cool in summer while preventing moisture build-up and condensation. Many garden rooms also include radiator heating as standard, ensuring a warm and cosy environment year-round. This makes them an excellent home office solution, offering comfort and efficiency in all seasons.
Adding a dedicated workspace to your property can significantly boost its value. Depending on factors such as size, design, and location, experts suggest this improvement can increase your home’s value by anywhere from £50,000 to £100,000. A well-designed garden room enhances your living space and appeals to potential buyers looking for a versatile area for work or relaxation.
Garden office prices start at £12,485 for a compact 2.28m x 2.44m internal space, ideal for one person. Prices increase based on size and optional upgrades.
The largest option, offering 30 square metres of internal space, costs £43,450. We provide over 70 size configurations, with measurements increasing in 0.5-metre increments, ensuring you find the perfect fit for your space and needs.
Garden rooms are safe and comfortable spaces to work from all-year-round. Our buildings are breathable, allowing for the transfer of air for a fresh and condensation free workspace. Opening windows are included as standard in the price of every building, including trickle vents and premium double-glazing. We also include an oil-filled radiator in the price of every building, keeping you cosy in the colder months.
You can make a garden office with a self-assembly garden room kit. These prefabricated garden rooms are easy to assemble and drastically lower the cost of a garden room. Starting from £9,995, you can have a cost-effective and easy-to-build garden office in two days. Click to see more of our DIY garden rooms.
You can get Wi-Fi in your garden office by using hard-wired ethernet cables, home plugs, or a mesh network. These offer a strong internet connection to work optimally in your garden office.
A high-quality garden office can last 25 to 30 years or more with proper care. Its lifespan depends on key factors such as premium materials, expert craftsmanship, and regular maintenance. Investing in durable timber, effective insulation, and superior weatherproofing can significantly enhance longevity.
Choosing a reputable garden room company with years of experience designing, manufacturing, and installing outdoor buildings ensures a well-constructed and long-lasting office in your garden.
In the UK, the average cost of a garden office typically falls between £13,500 and £21,000. The final price can vary significantly based on factors such as the size of the structure, the quality of materials used, the complexity of the design, and any additional features.
To give you a clearer picture, here’s a breakdown of common price ranges across different build types:
| Type of Garden Office | Cost |
|---|---|
| Basebox – (Budget Friendly) | £9,995 |
| G Range (Core Range) | £23,790 |
| A Range (Apex building) | £30,995 |
| X1 (Premium building) | £49,950 |
Generally, building your own garden office tends to be the more budget-friendly option. By going the DIY route, you can avoid extra expenses like installation and labour fees that usually come with pre-built models. If you’re confident with DIY tasks, constructing your own garden office can be both cost-effective and personally rewarding,

In most cases, adding a garden office won’t increase your council tax. However, how you use the space can make a real difference.
If the garden office is used for a non commercial purpose like working from home, hobbies, or occasional admin, you won’t see any changes to your council tax bill.
Ultimately, each case is assessed individually, and local councils may have slightly different criteria, so it’s always a good idea to contact your local authority for guidance if you’re unsure.

Fantastic Room in a little London garden!
We now have an amazing room at the bottom of our garden that fits in beautifully and feels as though it has been there for ever. All the staff were incredibly helpful and friendly and the entire process was very straightforward.
by Peter
Can’t beat a Green Retreat!
We cannot recommend Green Retreats highly enough, compare their offer to anyone else and I think they will win the day. The finished result is a garden room of class and something to be proud of. Value is what you get as an overall package and experience, not what just the price tag states. Choose low maintenance materials and you cannot do better than Green Retreats, they simply are very hard to beat!
by Mark
I’d recommend them to anyone
Each element of the team that came were all extremely polite, punctual and very professional. The quality of the materials are extremely high and the overall quality of the garden room is amazing. It’s fabulous to be able to sit in a room outside to work and to relax and enjoy the garden to its full potential. Green Retreats have been superb throughout the process, and we would not hesitate to recommend them to anyone!
by Sarah Levin
What a great company!
The customer care and communication, from the start of my enquiry through to the installation has been exemplary! I’m so pleased with my G2, it not only looks great but it is a
first class product down to the last detail. I can’t recommend Green Retreats highly enough and I’m super excited to relocate my art studio into the garden! Thank you Green Retreats.
