We have just the most amazing 1 bedroom annex built in our garden. The Team at Green Room are fantastic, nothing was too much trouble from changing the design a few times to putting up curtain poles in the finished annex, Brian has a wonderful team and every single one of the workers were polite & helpful.i would highly recommend The Green Room if anyone was thinking of an annex. We did several months research and decide on The Green Room and we are so pleased we did. The finished annex has far surpassed our expectations. A massive thanks to every single person who helped with build.

The build of our Annex took 4 weeks, including clearance of the build area.The site access was not at all easy but the team did a great job.The people whom made up the site team were extremely helpful and conscientious. We were not on site for all the build but did turned up intermittently to "check on things".The Green Room staff were all helpful and gave information and advice as needed or requested, We found them easy to approach and work with.The finished result surpassed our expectations and we are extremely happy with our build, the attention to detail is superb.We would whole-heartedly recommend Brian and his team to anybody looking to have prefabricated or modular building work carried out.

When we decided we wanted to build an annexe in our garden for my Dad we researched our options carefully. The Green Room had such excellent reviews I wasn't sure they would be able to live up to our expectations but they have exceeded them. Brian has been wonderful to deal with from start to finish; never pushy, always patient with our many queries and quick to respond. His product is excellent, such high quality with no expense spared we couldn't be happier with the outcome. Tom and his team were superb, true craftsmen and always friendly and polite. I can't recommend the Green Room more highly and if you are lucky enough to have enough garden to build an annexe then this is the ideal solution to a problem many families now face with an elderly relative who needs indpendence and also family close by. Thank you so much to Brian and his super team for everything.In my Dad's words "I am delighted with the result. It is everything I wish for. The team were friendly, polite and hardworking and very supportive when the odd hiccup occurred. The finished product is beyond my expectations and I am so looking forward to spending my years in such a lovely home as this. Thank you Brian for a job well done." Steve Pascoe

From start to finish the excellent service and attention to detail were to say the least outstanding. From obtaining the planning permission (in our case not without difficulties) to the choses of both internal and external finishes,to the fantastic workforce, every detail was expertly taken care of in a professional way.No extra hidden costs, every detail was expertly managed. I cannot praise The Green Room and there wonderful team highly enough.We now have our forever dream home.Thanks to this fantastic team.

The Green room installed a lovely state of the art annexe for my father in our garden finished at the end of January. It was designed around my fathers needs but also allowed him to have his own independence. Brian came and spent the day with us going through how the annexe would be built and the materials which would be used. My father was happy so Brian up with a design and after a few changes made by us we agreed for the annexe to be built.The green room dealt with everything from the planning permission to the full installation of the annexe including waste services and electrics which was fantastic for us.The team that built the annexe were a delight to deal with and my father has settled into his new home.I would recommend that anyone building such an annexe in their garden certainly considers the Green Room as what you see on the website is what you end up getting built in the garden.

Right thru the process of ordering, planning and building it has been a pleasure to deal with Brian and his fantastic team.No problem too small or large was any bother to them, they just efficiency kept going. The team is a well oiled machine that only has one purpose in mind to please you as the customer.We would willingly deal with The Greenroom again and again. Do not use anyone else for your project.....this is by far the best you can get.Would give a hundred stars if possible.

From my first meeting with Brian until I moved into my granny annexe nearly 8 months later, the whole processs was seamless and stress free. My daughter and her family bought a lovely home with a fabulous garden, the intention was always to build an annexe for me and with the help of The Green Room we have created a perfect home for me in their garden. The planning and designing process was fun and with Brian's help we came up with a design that was just right for my needs an fitted perfectly into the garden. We had work to do clearing the plot before The Green Room guys came on site but once they arrived it took them 5 weeks to complete the build and then I moved into my beautiful new home. I am delighted with every aspect of it and hope to live here for many years enjoying the luxury of having my family close by. I would not hesitate to recommend The Green Room to anyone who was looking to create a room, home or office in their garden, the whole team were professional and nothing was too much trouble for them. Thank you to The Green Room fro giving me my independence and the joy of living with my family but in my own beautiful home.

The Green Room provided us with a fully managed, faultless service to create a wonderful two-bedroom granny annex in Reigate, Surrey. The service included obtaining planning consent which was seamless, annex design which was responsive to our needs and preferences as well as construction which was fast but always professional. The Green Room team that worked on site were all craftsmen who were clearly prepared to go the extra mile to get the job done – as long as we kept supplying the coffee and biscuits! In truth, they cannot be rated highly enough. The finished annex is just perfect for its occupant, 87-year-old Iris, who is grandma to our three grown sons and great grandma to our own four-year-old grandson. Iris feels totally secure in her new home and it has genuinely given her a new lease of life. Well done Green Room and thank you.

Brian and the Green Room Team are thoroughly professional and their workmanship is excellent. The completed Garden Room is beautiful and has more than satisfied all my expectations. I will recommend them to anyone interested in adding value and utility to their garden.

We would definitely recommend The Green Room.My daughter has now been in her new, wheelchair accessible, annexe for two months and absolutely loves it. It would be hard to find enough superlatives to describe how perfect it is. From the day we discussed our requirements with Brian, through his creating the drawings, obtaining planning permission and providing a friendly, professional building team, we could not have been catered for better. We were given a fixed turnkey quote, and were consulted at every stage. Our annexe even included things we hadn’t thought of, such as perfect fit blinds coordinating with our intended colour scheme, and internal pocket doors which not only save wall space but also allow easier wheelchair access.

The Workmanship ,Designer precision and versatility of all the people involved with The Green Room,totally took our breath away. The decorater commented that he had never seen such a perfectly constructed house. Brian and Caron made the whole thing go with seamless efficiency and the construction engineers were tidy, courteous and went out of their way to explain what stage they were at,True professionals. We wouldnt hesitate in recommending The Green Room to any one considering a project as depicted in their brochure. Brians drawings and his ability to liase with planning and the legalities involved, took all these pressures away from us completely and made the whole journey from concept to fruition a pleasant experience.We totally love our New house.Chris and Nades

We are simply blown away by our new garden room! During the process of planning and designing our room we had an optimistic vision of how it would turn out, although slightly skeptical of the company’s grand promises (we were assuming the usual ‘salesperson patter’). However, seeing is believing and the finished article is even better than we imagined. It was a tough job as the weather was awful, with snow wind and rain to contend with. The amazing team battled on regardless. We now have our 7x4 m garden room 30 m from the main house, with toilet, internet, TV point and endless possibilities!After the price was agreed, there were no additional charges, despite the job taking substantially longer than planned, due to weather and other unforeseen difficulties (e.g. 8 inch concrete to remove to lay sewer pipe, requirement for pumping station etc). The whole process from designing and planning application to handing over the key was managed perfectly, with us being kept fully informed.The Green Room did a great job assuring that all the regulations were met and all the correct documentation was provided to us at the end. They supply and install only the very best quality materials, even upgrading some materials (cladding and decking) over what we requested without extra cost. It is clear that they take immense pride in their work.We plan to use the space as an office and play room and it will enrich the lives of all the family.Thank you The Green Room. Ultimate professionals and very highly recommended.

We have just had a 3x3 green room installed. We have to say that from the first enquiry to the completed project our experience with Brian and his happy team has been fantastic. They have been helpful and professional. The building itself is as expected and of a very high quality. It arrived on time and the erection team did a superb job. We would highly recommend the Green Room to any prospective client.

We have just had a one bedroom annexe completed with a separate kitchen bathroom and living room in coventry. From start to finish Brian was absolutely brilliant and bent over backwards to design and install an annexe that was above and beyond expectations. The build team were very efficient and professional and Tom was just amazing a thoroughly lovely man. We are absolutely thrilled and cannot praise everyone enough. Thoroughly professional helpful and friendly. Thank you so much to everyone.

We are very pleased with our quality new garden office, later on next year it will become our company canteen.When we have the landscaping around it completed and also the outside seating areas on the South and East side we will send photo’s to the Green Room. We are planning for it to become a green and relaxing central point for all our staff in the middle of our company grounds. If all goes well we are hoping to add a sedum roof to it next year as well. We would like to thank all of the Green Room team for an excellent service!

We had an ageing wooden summerhouse that was drawing water in at floorboard level.This was at the end of extensive decking that didn’t get much use.So we made contact with the Green Room to see what they could offer, our idea was to look for something more usable and as maintenance free as possible.Plans were drawn up, discussed and agreed. The old summerhouse was taken down and within a few days our new Garden Room was up. The quality of the final product is amazing and will add substantial value to our property.We would recommend the Green Room to anyone thinking of having an outside room.

Love my granny annex! From start to finish Brian and his team were superb. I have lived in it for a while now and would recommend it to anyone thinking of doing the same. My daughter calls it my dad pad and is on hand if I need her. I have no hesitation in recommending this company to anybody wishing to purchase a garden annex.

The process from start to finish was very positive and efficient. Our initial visit with Brian was very informative and thorough, the process of having the garden studio built was quick and an example of great workmanship. The main selling point for us was the way in which the product was designed and put together with literally everything included, this took a lot of the hassle out of the process and meant we had a finished garden studio ready to use.We would recommend this company and their products.

Brian from the Green Room sat down with us and we explained our needs. He designed everything perfectly and whilst the work was being undertaken he stayed in regular contact with me by email, text and phone. The guys that did the work were extremely hard working and friendly and often worked in freezing conditions without it stopping them from working. The garden room i now have is perfect and it feels like a room in our house.

I am absolutely thrilled to bits with my new granny pad. It was originally going to be for my daughter but when it started to take shape I decided I wanted it instead. The Green Room designed and built a lounge /kitchen on the side of an existing garage and the garage became a bedroom with en suite .What a transformation!! A very professional service was given and first class workmanship was provided.Nothing was too much trouble for Brian and his team !! A big THANKS guys from Cath Jackson Stockport
