We are completely transparent with our prices.
You can find comprehensive breakdowns of our prices in the following easy to find places:
- The starting price of each product and each individual size can be found on the product pages on our websites and in our brochure pack.

How much is a garden room?
Garden rooms start at £11,995 all-inclusive for a 2m x 2m internal sized building. Prices increase from here onwards based on the size of the building, with sizes reaching up to 30 square metres internally.
- The smallest garden rooms cost £11,995 based on a 4 square metre building.
- The largest garden rooms cost £25,495 based on a 30 square metre building.
Between the smallest and largest sizes there are over 70 different size configurations to choose from, based on half-metre increments.
If you are looking for a building that is larger than 30 square metres internally then you will require an annexe building. Annexes comply with building regulations and as such are much more expensive in their construction.

Every listed price of our buildings comes with all of the ‘essentials’ as listed above. There is also the option to upgrade and add other items either through us or retrospectively after we have installed the building.
We can offer upgrades such as bi-fold doors, air-conditioning, underfloor heating, plastering and painting, and much more.
Many of our customers have professionally fitted bathrooms or kitchenettes added to their buildings after we have completed our installation. This is not something we can do for you, but we would be happy to discuss the project with your chosen contractor to ensure they are comfortable with the building’s structure.

- Electrical connection
- Potential Planning Permission fees
Electrical connection from your home power source to your garden building is an unknown until you have a design consultation/quote completed, either by your chosen garden building company or by your preferred electrician.
Green Retreats will quote for electrical connection during your free design consultation. We also have an electrical arm to our business that will carry out the work – meaning we do not sub-contract any of our work and will take full responsibility.
Depending on where in the country you live there may be a delivery charge. We never subcontract our building work to ensure full quality control. Our delivery charges are there to cover the extra travel as well as accommodation for our teams should they need to stay overnight to complete the work. Our buildings only take between 1-5 days to install, so delivery charges are kept to a minimum.
A garden building can be installed on the ground that is level to within 200mm. We ask that all levelling if complete before your building is due to be installed, which may incur a cost from your chosen landscaping company. We do not carry out groundworks like this, only the foundations and only once the ground is level. Foundations are included in the price of your building. During your design consultation, we can help advise on what groundwork, if any, that you may need to outsource.
We do not offer any landscaping services at present. However, we are happy to liaise and with your chosen landscaper to ensure that your garden project goes as planned.
Potential Planning Permission costs (only if you need them)
Garden rooms generally do not require planning permission as they fall into permitted development. There are certain areas in the country that require planning permission, such as AONBs, and certain restrictions based on size and placement of the building – all of which will be clarified during your free design consultation.
If you do need planning permission there is a cost involved. We can help take care of planning permission application on your behalf, helping to make the process easier.
Are garden rooms good value for money?
Adding a garden room to your home is much cheaper than other forms of home extension, making them incredible value for money.
Our garden buildings are designed for quality with a 10-year guarantee and are designed for a 30-year life. Choosing a company that use only premium grade maintenance-free materials, such as those used by Green Retreats, ensures that your garden building will be a lasting investment too.
Do garden rooms add value to your home?
A quality built garden room from a reputable company is the safest way to translate the value of your building into the value of your property as a whole. Many times we have seen our garden buildings listed as a selling point for properties which have added value.
Adding a garden building to your home as a way to make extra is a highly cost-effective way to extend your home. Potential buyers may also share the same desire for extra space as you did when you had the building installed, and value the added space as part of the package.
Modern Garden buildings are becoming more and more recognised, and as such, the value and benefits of having one are becoming more commonly appreciated.

Our garden rooms are priced based on the internal sizes rather than the exterior footprint, making it easier for you to plan your work space. A commercial unit from Green Retreats could end up saving you a fortune from the costs of renting a workspace alone. The price includes base, installation and VAT so there are no (nasty) surprises when it comes to final payment.
