Great new space delivered with no fuss. Comms throughout great. I had a bit of a rethink after initial order and Ralph and the team there were flexible and helpful. They turned up when they said they would, were polite and friendly and installation was sorted in two days with no hitches. Really can't fault the process and love the new office.

I am delighted with my new lean-to. I was initially hesitant to this concept but from get-go Ralph alleviated all the concerns/questions I raised.
I'm rating this job a 5 STAR STAR STAR!! Ralph and the lads did an amazing job. From start to finish it took less than 4 days, including electrics. The actual build itself took two and a half days and the size of my lean-to was 4.8m x 4.8m, so it wasn't small. They were always happy, smiley and polite. They cleaned up after each day's work, no mess no fuss. They were a class act and a real pleasure to interact with, always professional. I cant say that

Absolutely top class service. Professional service from start to finish. The company supplied and fitted an outstanding Garden Room .. The unit went up completely in less than 6 hours. We are so excited about this extra living space. Ralph kept in touch with us regarding installation and start date etc. He and his team are a polite and… professional team. We had a lovely guy who came next day and did all the electrical fittings for us. Had no worries about leaving any of these guys here at the house whilst I went out. Can’t recommend enough. Outstanding doesn’t seem enough to

Ralph and his team at CS Garden Offices are simply brilliant. The customer service is second to none and our office looks amazing.
Ralph went above and beyond when designing an office for the space we had. Offering his expertise and experience to make sure we had everything we had wanted to include. The maintenance free exterior was a big factor for us and was one of the main reasons we contacted Ralph and his team.
The finish is great and installation only took a day which was a huge bonus.
I highly recommend CS Garden Offices!!

We've had two garden offices from CS Garden Offices and have been very pleased with them both. So great to have a fully insulated and double glazed office at the bottom of the garden, it's made a huge difference to our working lives. We built the first one ourselves, which was pretty easy and felt like a great accomplishment! When we moved and bought another larger version the team at CS built is for us is less than a day! Looking forward to receiving our lean-to extension/utility room in a few months.

We are so delighted with our new extension to our home. The Lean-to product was perfect, is brilliant quality and really attractive. I have been speaking on and off to Ralph for over a year with different ideas & plans of what we might do, and every interaction has been extremely helpful & very professional.
The build was delayed by several days due to weather and Ralph & the team kept us informed and leapt into action as soon as there was a break in the rain.
I cannot recommend CS-Garden Offices highly enough and would say this has been one of the easiest, stress free interactions with a company

Great job! Ralph and the team did such a good job with our lean to extension. Absolutely love it and we hang out most of the time in there. It is surprisingly well insulated and we have used it all winter without having any heater installed. The process was super easy and stress free from start to finish. Installation was a 2 day job and I couldn't believe we ended up with a room in just two days! They were very friendly and professional, and even cleared up afterwards. I waited a few months to leave a review, and I am so happy that we have had no issues whatsoever with the structure despite the

Can't recommend Ralph and his team enough. They've turned a useless space behind our house into a large, light, attractive extra room at low cost and with no fuss. Ralph was really helpful in getting the design just right to fill the space and the whole thing was built in two days with no disruption at all to the rest of the house. Really pleased we found this company.

Ralph and the team came and installed an office in our garden, and the whole experience from start to finish was outstanding. Ralph is extremely responsive and couldn’t be happier to help spec up the right office for us, even after 3 or 4 revisions! The installation was smooth and quick, and the team were all extremely friendly and courteous. The office itself is an incredible space made of high quality, long lasting materials and we’re all really happy! I couldn’t recommend CS-Garden Offices enough - thank you!

Ralph and the team at CS Garden Offices have been brilliant from the start, giving very helpful advice to ensure we got everything we wanted out of the room and even assisting with our planning permission drawings. The modelled images they send over are brilliant and really help you be able to visualise what it will look like.
On the installation day the team were friendly and professional and took real care with the build to deliver a great product. We are delighted with our room and it’s been a great value was for us to get more space.
We have had a great experience from start to finish and

CS garden offices have provided us with an amazing addition space. They have been a pleasure to work with being professional and friendly. They run a tight team of professional fitters and electricians. I Would thoroughly recommend them to anyone looking for a garden room/office space.

Very, very happy with my garden studio from CS Garden Offices. I was interested initially as they offered a quick turnaround and an insulated and low maintenance structure (I want to use my space, not be painting or sealing it every five minutes). Ralph and his team worked to the footprint of the small space I had available and were very… understanding while I tweaked various aspects of the design. The end result was put up in a day with the electrical team following up the next day. I had control over every aspect of the build and I can honestly say I am completely satisfied with the result

Well what can I say. Delighted with my new building. After alot! of quotes for extensions, conservatories,insulated sheds etc..I came across CS Garden Offices and found the perfect solution for me. They have given me two extra rooms off the back of my house for a fantastic price. The build took about 3 days (it was a big unit) and Ralph and his team were a pleasure and nothing was to much trouble. Having now moved in and using the rooms they are bright and airy and really feel like part of the house already. Highly recommend for an affordable extension to your home or for a room/office to use in

So pleased with my CS Garden Office. It is what they say it is, solidly constructed and very aesthetically pleasing on the eye both internally and externally. The team putting it up were quick, efficient and could not have been more helpful and Ralph was always on hand to make sure things were going to plan. Installation took about a day and a half. I have now been using the office for over a week in the coldest of conditions and have felt really well insulated and warm. I can sit and work with a great view of the garden through the full length double glazed units. Fantastic! Thank you Ralph and

We had our lean to built whilst away on holiday and so came home to a high quality, well finished product. Having had it for a couple of months we are still very happy with it! Ralph was very responsive to my questions and calls. They are reasonably priced and the lean-to we bought provides a well insulated extension to our home. I highly recommend them!

The process was simple & stress free from the first phone call. Ralph was incredibly helpful & got back with drawings pretty quickly.
The installation went well - in one day as promised! The end product was stylish & looked far more expensive than the actual cost.
I would highly recommend this family run business - in fact I'm about to buy another lean-to from them. We are so pleased with the extra space we now have - pictures will be posted soon.
