Bathroom Fitting- 9 Feb 2019
Extremely pleased with the job Remi did. At the quoting stage he was upfront about costs we might not have considered, but still ended up being very competitive on price. During the job, he communicated clearly when he came up against issues; his fitting was to a high standard; he was on time and worked as long as he needed to each day to finish the job. His after-care was also good, as he returned to fix a related issue that arose during the work without quibbling; he also came back to complete fitting an item whose delivery had been delayed. Overall, I'd definitely hire him again.

Extensions- 4 Jul 2026
We posted our building project on MyBuilder for the construction of a new outbuilding. We received a number of responses and quotes and selected EDSS Ltd. My elderly mother had used EDSS Ltd previously to do a number of renovations to her house and we found EDSS Ltd’s quote competitive and fully broken down. The work completed to date has been high quality with a high level of attention to detail. Stefan and his team managed the project from start to finish. This has included liaising with building control and other parties. We did not have to worry about any detail and Stefan always goes the extra mile to reduce any inconvenience. Stefan and his team were reliable, hardworking, approachable and always willing to discuss any questions we had during the build. The work was completed to a very high standard and we were kept informed throughout the project. We have no reservations in recommending EDSS Ltd and are happy for customers to see the work.

Extensions- 30 Sep 2025
Overall, I’m very pleased with the work Marin has carried out for us and I’m currently in the process of instructing him to do more work. Marin built a high spec cedar shed for us with electrics and plumbing, some brickwork and laid composite decking. Marin came across, honest and reliable, which in itself is rare. He was on site most mornings to make sure his tradesmen were on the right tracks. Like with a lot of these things there were some issues along the way and I was highly impressed by Marin’s ‘no quibble’ approach to rectify any problems. I myself have a high attention to detail and am quite indecisive (nightmare client) and Marin was happy to work with me with changes to the project without incurring extra costs.

Restoration & Refurbishment- 5 Jun 2026
This builder is not honest; he didn't do the work to live up to his verbal commitment to quality. He refused to include the electrical work he had done on the invoice because he did not want to issue an electrical safety certificate. He is not a professional, and we argued 2-3 times about not doing the quality work and left work, giving unethical reasons. His work laying garden slabs was of poor quality; the slabs were moving when walked on. I asked him to do it again, which he said he did, but still he left the slabs moving while walking. I am thinking of legal action against him. I will not recommend him to anyone. PLEASE AVOID HIM GIVING ANY JOB IN YOUR BEST INTEREST.

Architecture- 5 May 2018
Contracted to provide options for a new garage office and storage solution. They turned up promptly and were very polite and professional. Through many discussions they ultimately offered up a very good bespoke solution for our situation and once planning is approved we will have no issue with looking to them to complete the actual build. We have had a lot of issues in the past finding reliable trades but with ArhiTERRA design and build we felt confident in their ability to both visualise and implement the build as well as follow through on their promises. I would say that for anyone considering discussing a project with them that it is worth your time to at least have a meeting with them and judge for yourself.

Extensions- 5 Oct 2022
I am very pleased with the work Josh and his team did in building my rear extension. They were a friendly and hard working bunch and very respectful of my space. Josh did a great job in project managing the work and making sure things were progressing as planned. Any snagging items were dealt with promptly. I would hire them again if required and recommend them to anyone who wanted to have building work done.

Bathroom Fitting- 25 Feb 2022
This was the best experience I have ever had with a team of builders. Aldo and Leo were polite, organised and their workmanship is of a very high standard. They replaced the bathroom in our rental flat, and it looks really smart. They also refurbished the kitchen, replacing flooring and decorated the whole flat. We have just shown it to an estate agent as we are planning to sell it and they were very impressed. Aldo was very helpful in making suggestions of small changes that would save us money and delivered the project on time and right on budget. Would recommend them and will certainly use them again.
