Extensions- 22 Nov 2020
In my opinion would never use NSH again. Several issues throughout the build which in the end one took court action to resolve. Site was a constant mess and found Neil's attitude rude at times. Not once did he apologise for any issues. Have done several new builds/extensions in the past and this has put myself and wife off ever doing one again.

Extensions- 20 Nov 2019
Matt of Pro Build (East) Ltd. was instructed to complete a home extension on my Victorian Mid-Terrace property at the beginning of July 2019. Matt initially replied to my MyBuilder advert promptly, came to view the job within days and could start the next week (in hindsight, probably not a good sign). He started work on the Monday, providing a quotation and an expected completion date of 3-4 weeks later for the complete extension including removal of waste, plastering and external rendering. Throughout the build, Matt's communication was prompt, replying to emails, phone calls and text messages mostly within the same day. Unfortunately, on a number of occasions problems arose with the project and I was frequently to blame for certain aspects, for example it was my fault that the roof could not have slates because the roof was built at a low pitch - however the quote included slates? The quality of workmanship throughout the build was very varied, requiring Matt and his team to return a number of times to re-do work which was deemed unsatisfactory by me, other workmen and the building inspector. There is quite often a number of excuses for why work has not been done, or why it has been done to a low standard as opposed to correcting the issue without argument. In the end, the whole build took 14 weeks to complete and remained to have a number of snagging issues, I would not personally recommend this company for larger works such as this.

Extensions- 3 May 2026
From start to finish, Kingsley kept us informed of what was happening and when, how much things would cost, gave suggestions about minor changes and generally made us feel like we were active in the whole process. Yes, it was stressful for us at times, but he was doubling the size of our floor plan, moving the kitchen while we were still living in the house. He did make it as easy for us as he could, leaving appliances working for as long as possible. The team of contractors he works with are brilliant, willing to go above and beyond to get the job done perfectly. He is very grateful for cups of tea and was happy to let my 9 year old nephew help out now and then. Kingsley is a superhero in my nephews eyes. Really pleased with the outcome of my build. Would definitely recommend Iris Construction.

James is diligent, communicative and constantly strives for quality. James completed our complicated porch extension and was very helpful at providing advice and options. The work that James carried out was of a very high standard. James also kept us up to date with progress and works ahead which allowed us to plan effectively. Everything was also very well managed and safe. We would wholeheartedly recommend James for those looking for works and would be in touch with any future plans we have.

Extensions- 25 Jul 2020
We found A F Robertson through the My Builder website, the excellent reviews from previous clients were very helpful, we have since found them to be honest and accurate, and in line with our recent experience of having Alex and his team build our extension. There is little more to add, only to say we would recommend this company to others and will contact Alex again for any other projects we may have in the future.

Edwin’s Carpentry
No reviews yet
Extension Builder in Stowmarket
Hello my name is Harry Edwin. I’m a self employed carpenter with 7 years experience in Carpentry and 2 years in Groundworks. I worked for a timber framing firm for 3 years and received my level 2 NVQ in Carpentry and Joinery from West Suffolk college. After I received my level 2 I went self employed doing subcontracting and private work where I learnt a variety of different skills from making bespoke French doors with oak framing to fitting trussed roofing. I’m very confident in my experience and I’m always eager to learn from others or try things I’m not too knowledgeable in as I love a challenge. I’ve done most aspects of carpentry including A lot of Joinery, 1st and 2nd fix. I also started my career in construction as a ground worker where I learnt a few aspects from that as well such as Fencing, slabbing, trenching and curbing. I’m always looking for new things to do and have always been proactive on site. I work in and around the Bury st Edmund’s Area but no job is too far for the right money I say. Please reach out to me if you’re interested in getting to know me or if you are wanting to see any of my portfolio of works I’ve carried out for my happy customers in the past. Thank you Kindly

Bricklaying- 21 Jul 2026
I've run my own building firm in the Southwest for 25yrs. I came here to project manage a job for some very dear friends. Needed a local brickie and after chatting to him, knew Mark was the right man for the job. He and his team have been nothing short of brilliant. Punctual, great communication from the outset, polite, highly knowledgeable, great work ethic and extremely conscientious of the quality he stives to leave in a job. If he was operating in my part of the country, I'd have him on all my sites in a heartbeat. The clients who actually own the house we've just put a lovely double extension on, are over the moon with the result, largely due to Mark's efforts in getting it built. Easy 5* review to write.

Extensions- 27 Jul 2018
Steve and Andy are absolutely brilliant. Steve initially came to quote for our job and we instantly knew he was the one we wanted to build our extension. We were very impressed with his experience and knowledge and his quote was competitive. Both Steve and Andy arrived every day they said they would and with their bubbly personalities, made a usually stressful experience, feel like a walk in the park. With 3 children, 1 dog and 2 newly released kittens, they accomodated us all. They communicated with us throughout and kept us informed daily. They handled the building inspections efficiently and professionally. Our single storey extension they built, has been completed to a high standard, incorporating roof lanterns, a window and bifold doors. It has made our family life easier, with the addition of space for a new kitchen and downstairs cloakroom, with the old kitchen becoming a bedroom for our eldest. Thanks so much Steve and Andy, you almost became a part of our family and we miss you already. We have no hesitation in recommending G L Building Services and suggest prospective customers don't delay in making that call!
