We used Stuart to carry out some alterations to our kitchen, convert our garage & construct a link between the two. From the moment Stuart quoted us for the work I was struck by how diligent he was, coming back to discuss his quote & being very clear in everything he had included & equally anything that wasn't. We were delighted that his diligence & care extended throughout the project & to the work that he did, he clearly cared that everything was done correctly, as if it were his own home. He put thought into everything he did & the sequencing of the work, making sure there was as little disruption to us as was possible. He also communicated to us throughout about his plan and any issues he encountered. We are thrilled with the end result, Stuarts work is of a high standard & competitively priced too, I couldn't recommend him highly enough.

Extensions- 18 Jan 2020
In October 2018, I asked Michael to do a rear part single storey part double storey extension. Michael completed the job mid January 2019, which also included relaying the patio, fitting a pre-bought kitchen and building a new porch. Michael, Bill (the electrician) and the rest of the team have done an excellent job transforming our home into something so much more than it was. I was very impressed with his work ethic and his knowledge, and appreciated the advice he gave us which showed his experience. The electrician also was able to successfully rewire our home to bring up to the required standards and was willing to work on weekends to get the job done (that was partly our fault, sorry!). Any issues and disputes, of which there were very few mind you, were dealt with promptly and properly. All in all, if you're looking for a trustworthy, high quality builder in the Hitchin/Letchworth area then do get in touch with Michael. Thanks again for the excellent work! Also, if you'd like to see his completed work, please drop me a message and you're welcome to come and have a look at the work that was done.

VERY HAPPY. Jay was very efficient in his work. While the the quality of his work was very good, what surprised me was the speed with which he completed it. The cost was very reasonable too.

Landscaping- 5 Jun 2022
We received several quotations for the landscaping of our rear garden, Groundworks quote was competitive and after having met Donaldo we felt comfortable they could do the job. Donaldo and his team were reliable, professional, well organised and considerate of our neighbours throughout. Donaldo maintained good communications when issues arose or aspects of the landscape design needed our input to ensure the finished outcome was to our requirements or liking. The works were complete within the timeframe agreed and to the standard we desired. I would have no trouble recommending Groundwork’s or appointing them for similar work again.

I would not use Dan again. Complete lack of expertise on certain aspects of this build resulting in a lot of stress for me. Failure to gain necessary permissions despite Dan's reassurances at the time. An error on Dan's part related in the entrance to my property having to become much smaller than I needed. Disappointed overall.

Extensions- 7 Jan 2020
We have engaged Charlie through myBuilder and he was very prompt with his feedback. His engagement was effective and he gave us the time and attention as we went through the selection process with a few candidates. Once we made up our mind he was quick again to come up with the final quote and accommodated our final changes (of which there where a few). I think it is important to highlight that on a project like this one it is a good idea for the client to have a clarity of the scope and specification to the detailed level - it helps the builder with the scope and the quote. Through the project Charlie was effective in sticking to his timelines and was very proactive in lining up the other trade (although it was not an easy task at times). We have had our hiccups and challenges when things did not go to plan, but those where resolved in a very professional manner with mutual respect, understanding and attention from Charlie for which I m grateful. Overall we are pleased with the work delivered and many of our friends are still amazed at the speed of our project delivery. Will be happy to endorse Charlie or provide any more detailed feedback if required.

Jack came and quoted to lay a new patio and a shed base. He listened to exactly what I wanted (something other workmen didn’t do!) and came back with a very reasonable quote and said he would complete the job on a weekend as I wanted it done asap. From start to finish Jack was really polite and friendly and worked really hard to get the job finished - so much so, I’m adding more bits to the garden and will get Jack back over to do it!

Decking- 3 Jun 2026
Anthony did a great job from start to finish. Having had a few quotes, some cheaper, I decided to hire Anthony for the job as his quote was fair, thorough and clear about the process, materials, time needed, I did not get this assurance from some of the cheaper quotes. He listened carefully to what I was looking to do and make some good suggestions to help achieve the look I wanted for my decking. Communication was clear at all times during the job. Once the job started, Anthony was punctual each day, organised and ensured the site was kept clean at all times. I am very happy with the decking and standard of work achieved. I would highly recommend Anthony and AJK Building and would definitely hire him again for any future jobs.
