CS-Garden Offices
What customers say
Design consultations, site surveys and installation form a consistent chain of praise for CS-Garden Offices, based on Fareham Road in Gosport and reachable Monday to Thursday until 4.30pm and Fridays until 3.30pm. A detail many reviews return to is the speed and clarity of communication, with customers describing every query answered promptly from the first enquiry through to the finished build. Staff such as Paige and Ralph are named for their handling of quotations and onsite surveys, while installation crews including Andrew, James, Reiss and Oakley are praised for completing garden offices and gyms within a day or two, sometimes working through difficult weather without losing pace. Several accounts mention the insulated metal construction and online configurator, which allowed adjustments to size and price before any commitment was made, and more than one customer reports installation being brought forward rather than delayed. Electrics fitted as part of the build, including lighting and work around existing wiring, are also noted favourably. Buyers converting garden space into offices, gyms or specialist storage describe a low-pressure sales approach paired with practical guidance on suitable options. Across the feedback, the recurring impression is one of a well-coordinated process from initial design to final handover, with the Gosport base open through the working week for enquiries and site visits.

Would definitely recommend and have no hesitation to give a positive review. Service throughout has been excellent and questions answered promptly. They helped us decide what was best for us and gave us a walk round the workshop. The building install took less than a day to complete and everything was left clean and tidy. Electrics even less time, so in two days it's ready to use.
CS-garden offices built and installed a garden office for us recently, and the whole experience was fantastic. Communication was prompt and clear throughout - every single question we had was answered on time. They gave us plenty of notice regarding installation dates and were even able to bring the installation forward by a week, which was a great bonus. On the day, the installation team arrived right on time, worked incredibly efficiently, and completed the build in just 6-7 hours, followed by the Electrics setup. Highly professional service from top to bottom. I would highly recommend.
Can not recommend C S Garden offices enough. They have been very responsive to our emails with many requests to ensure we received an office to suit our needs. The guys installing were lovely and installed our office efficiently paying attention to detail. Can’t wait to move in!
Great work by the team here. Anthony was kind enough to show and explain the manufacturing process. Ralph did a timely onsite survey. Admin team kept us updated on the schedule and cost. Installation team was fantastic, ensured we were okay on every little thing. No pressure on sales, rather guided us on the process and what's good for us as customers. 'Doing it right the first time' is important for prefabricated modules and CS Garden offices team delivered a fantastic job. Highly recommended.
Absolutely fantastic service from start to finish. The lads arrived on time and got on with the job. They were checking with us to make sure we were happy with everything. Job completed in less than half of day. There was nothing to much trouble. We had to put the job back a few months due to health problems but for Antony in the office this was not a problem. Will have no hesitation in recommending CS gardens to anyone. Thank you all.
We chose our garden room following significant research, surveys and quotes from other suppliers but none could beat the quality of materials and competitive price offered by CS-Garden Offices. In particular, the long lasting, insulated metal construction was ideal for our need for storage of environmentally sensitive medical equipment. The whole process of selection through the configurator and adjustment of quotations was straightforward and communications have been excellent throughout with weekly updates. The installation was trouble free onto a prepared based using compacted MOT Type 1and gravel filled grids, completed in a day with great attention to our requirements by the team who were timely, polite courteous, patient and efficient. The quality of the finished office is great and we have no hesitation in recommending CS-Garden Offices, we would definitely use them again.
A very efficient build and high quality room. Everything was discussed with the team and laid out easily. The electrician had to deal with our houses awkward electrics too. Would highly recommend, especially for working from home people. (Picture is before lighting was installed)
