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

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

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!

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

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!
