We were proud to be part of Love Your Home and Garden with Alan Titchmarsh, where we designed and built a bespoke garden room for the Seesurrun family. Their son Aryan requires full-time care, and our garden room gave his mum, Manisha, a peaceful space to return to her design work.
The finished room opened onto a wide terrace with level access, a lift for Aryan, and beautiful landscaping that tied everything together. It was a thoughtful project for a remarkable family.
“The building is so well constructed and the team were a joy to have on site. I cannot recommend them highly enough!”

There are not enough complimentary words to describe my experience with The Green Room. At the outset Brian was always there for advice helping me to decide exactly what was needed for my Garden Annexe.
Now it is complete I could not be happier. All the staff are amazing and helpful. Nothing was too much trouble.
The workmanship is top quality and my dog Freya and I absolutely love our new abode.
So impressed with the quality of the kitchen. The shower room is just perfect.
One of the best features for me is the fully fitted wardrobe, shelving and drawers in my perfect cosy bedroom.
So do not hesitate to give them a call. You will be so glad you found them. Jenny

We had our first garden office from the Green Room installed in August 2017. It was installed quickly and efficiently and to date it has not needed any maintenance. Not even the beautiful green roof we decided to have installed as an extra has needed any maintenance. The changing colours of the different mosses and plants throughout the year have been stunning. It proved a favourite workplace for our employees.
As our business has grown further we recently decided to have a second garden office from the Green Room. It was delivered just as quickly and efficiently as our first garden office. It is absolute quality, the workmanship as well as the materials used. Our compliments to the Green Room!

So glad we picked Brian and his team at The Green Room. I did endless hours of research on annex builds and watched lots of videos. The final seal of approval for me was Mr Alan Titchmarsh. If The Green Room is good enough for him it is certainly good enough for me. From day one to the end, Ben and the lads were
superb and very trustworthy and meticulous. We have spent a bit of time in our lodge now and are thoroughly enjoying it. It is so quiet, very warm and the underfloor heating is a lovely bonus. I can’t recommend The Green Room highly enough.

If you are looking for an outside garden room or annexe look no further. You will not find a better company and customer experience. We’d been planning to build an extension or separate living area for my in-laws to live with us for a while, but didn’t really know what we were looking for. We contacted several ‘garden room’ companies and explored a hard build too. Out of everyone we contacted and spoke to Brian from the Green Room was the only person who very quickly agreed for a visit to discuss all the options and possibilities. We didn’t really know where to start with the whole process but Brian was completely transparent and helped us consider everything that we needed for fully accessible living.
We looked for more quotes and whilst the Green Room were not the cheapest no other company gave us the guidance and advice that Brian did. We felt in very safe hands right from the start.
We went through several design iterations until we were happy, Brian’s attention to detail when designing was incredible. We spent the summer clearing the site and team started work. It took 5 weeks and the end result is utterly amazing! Ben, Brandon and John were fantastic. Friendly, highly skilled and very efficient. The plasterers, electricians and plumbers were also exceptional!
The whole process just exceeded our expectations. We decorated it ourselves and my in-laws are now in and settled for Christmas.
Brian kept us updated regularly, managed all the deliveries, skip hire etc. You literally dont need to do a thing, except make a few coffees! Communication with Brian has still continued, with him checking in to make sure all is ok. We decided to add some grip strips to the decking ramp, add some handles to the outside and make an adjustment to some guttering. Within in a week Ben had ‘popped’ back to fit it all.
Don’t bother looking else where! You won’t be disappointed.

I would like to thank Ben, Brandon and John who worked on site for 6 weeks and who went above and beyond and nothing was too much trouble.

We would like to thank Brian and his amazing team for all of their hard work and dedication to build our 91 year old Dads 2 bedroom garden lodge. This was built at the bottom of our garden so that Dad can still have his independence but be close by in case he needs us. It’s such a fantastic idea and keeps family together.
The workmanship external and internal was top speck and only took 6 weeks from start to finish. The team were professional throughout the build and most importantly very friendly. Brian kept us well informed and the whole process was completely streamlined.
Thank you Green rooms we couldn’t be happier. 😃

The Green Room have just completed the most amazing lodge built on my garden for my parents aged 90+. The expertise and attention to detail of Brian and his crew has been amazing. I really believe this is the cost effective future for anyone who needs to have family close. This lodge was designed and purpose built to our spec and it’s really given them a new lease of life. Would 100% recommend The Green Room.

If you’re thinking about adding a granny annexe or garden lodge to your property, it’s natural to have a few questions. Here we’ve answered some of the things we’re most often asked. From how long it takes to what’s included in the price, this section covers the key points to help you get started with confidence.
Yes. Just like our annexes, our lodges are manufactured with SIPs panels for excellent thermal performance. They’re warm, quiet and energy efficient all year round.
Yes. We include trenching and connection to mains water, foul drainage and electricity. If a pump or additional works are needed, we’ll advise you clearly before we start.
Yes. Once we’ve visited your site and agreed on a layout, we’ll provide a full written quote. This will be a fixed price for the full project.

Absolutely. All granny annexes come with a fully fitted kitchen and bathroom as standard. Garden rooms can also include these features if needed.
If a dependent relative lives in the garden annexe, you are usually exempt from council tax. Rules can vary slightly depending on your local council, but we can help guide you.
For an annexe, you will typically need to apply for either Full Planning Permission or a Lawful Development Certificate (LDC) from your Local Planning Authority (LPA). We handle this process on your behalf.
Whichever route you take, our team handles the paperwork and contacts the local authority on your behalf. For further information, please see our planning page.

We don’t offer finance directly, but we can supply a detailed quote that you can take to your mortgage provider or broker. Because our annexes add value to your home, they are often accepted by lenders for equity-based loans.

Just fill out our quote request form or give us a call. We’ll guide you through the next steps from there.
