Green Retreats are the premier UK garden room company, specialising in fully-insulated garden rooms since 2005.

About our buildings

Built for UK climate

The Great British weather is notoriously unpredictable and highly changeable. The vast difference in temperature between our summers and winters mean that we need to be prepared for every possible eventuality when it comes to our homes and garden. 

At Green Retreats we understand the environmental demands placed on UK garden rooms and have perfected our construction especially with the British weather in mind. 

Warm in winter | Cool in summer | Dry and comfortable | + heating included in every building. 

insulated garden rooms

Our insulated garden rooms are designed for use all year round. We have engineered our insulation layers throughout our buildings to make a comfortable and healthy space to use that should feel as comfortable as a room in your home. Thick layers of insulation are paired with vapour barriers that directionally control the flow of air and moisture out of the building, keeping the inside dry and damp free. External heat is reflected away from the building, whilst internal heat is retained in colder months. What’s more, every building comes as standard with an oil-filled radiator – which, let’s face it – we could all sometimes use even in summer sometimes!


Planning permission rarely required

Garden rooms in the UK generally don’t require planning permission. This makes our garden buildings an easier and more cost-effective way to make extra space at home compared to the traditional alternatives (loft-conversion, extension, conservatory etc.)


Designed and built in the UK

At Green Retreats we design and build all of our garden room buildings ourselves, here in the UK. Our purpose-built production facility in Buckinghamshire is where we handcraft each building to order. We assemble your building into sections in our factory before we deliver and install them on-site. This makes the installation process much faster and more convenient for you at home, with installations normally lasting only 2-5 days on-site. 

Green Retreats UK Factory

– Never outsourced

We never outsource any element of our building construction, including the installation – meaning we have complete control over the quality from start to finish.


– Locally-sourced materials from the UK

As a UK garden room company, we want to help support other British suppliers. Britain is synonymous with the highest standards of quality, which makes choosing our predominantly British materials for our garden rooms easy! Over the years we have built fantastic relationships with our suppliers and are proud to source locally where possible. 

Being at the forefront of garden room building innovation means that we are continually looking at new methods and materials to keep our buildings the best quality in the market. Whenever we source a new material we make sure that it meets the following criteria:

1) Can the materials be sourced locally? 

As well as supporting local British businesses, it also helps cut down on transportation pollution and carbon footprint

2) Can the materials be recycled? 

We are an eco-friendly garden room company, with quality and sustainability at the heart of what we do. To ensure that our buildings have no negative impact on the environment we ensure that any new materials are made from recycled materials or can be completely recycled.

Garden Room Ideas UK

Garden space is at a premium in the UK, especially in the cities and suburbs. Gardens in new homes famously getting smaller and smaller too, making expanding on the existing house often very difficult to impossible. 

The traditional British home has all of the rooms in it allocated to a purpose when you buy it – dining room, living room, bedroom and – if you are lucky – an office or study. 

Where do you put your home gym, art studio, cinema room, man cave or home office for example? In America, they have basements for these kinds of ancillary uses – but even there what if you want fresh air, insulation and natural light?

A garden room creates a space at home that is free from the restrictions of the home; so that you can create noise, mess and have fun without the threat of disrupting the rest of your household. Our insulated garden rooms offer a year-round space solution for any idea you have in mind. Check out more of our garden room ideas and get inspired for your own project…


UK Garden Room Prices

We have no hidden costs when it comes to our garden buildings. We include all of the ‘essentials’ as standard, meaning the price you see on our website and in our brochure is that price you pay to have a fully operational luxury garden room building installed at your home (excluding electrical connection from your home to your garden building as we quote for this once we know the location of the building).

To personalise your garden building we offer a range of options included in the price or as optional extras – such as air-conditioning, plastering or bi-fold doors.
