His keen attention to detail is exceptional, and he leads a highly efficient team that promptly meets all demands and tasks.

I have enthusiastically recommended him to several of my friends, all of whom are immensely satisfied and grateful for his services. Furthermore, his pricing is fair and reasonable, leaving me extremely pleased with the quality of his work.

Restoration & Refurbishment- 3 Apr 2016
Vidas and his team did a fantastic job with our property refurb project and I can't recommend him highly enough. He completely stripped out property back to brick and rebuilt if from the ground up. We had some quite particular requirements requiring the removal and creation of new partition walls and Vidas was able to accommodate and direct us in how we could address each requirement. We are very happy with the finish and have had many compliments from other tradesmen on the quality of the work. We did have some minor snagging after the project was complete but Vidas was very accommodating in coming back to rectify these issues. I would highly recommend Vidas and look forward to using him again in any future projects.

Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

Tiling- 24 Sep 2025
I hired seasouth builds because not only did he give a really reasonable quote, but he also had knowledge of tiling over retrofit underfloor heating - which other tilers seemed to be really hesitant to work with. The job was done to an excellent standard - he’s a real perfectionist. It did take a bit longer than expected, due to some floor level issues which he didn’t account for when he quoted. I was really worried about the price increasing out of my budget when we started running over time, but I was so grateful to find that he was a really honest guy who stuck to the agreed quote and didn’t try to make it my problem one little bit. He was polite and friendly throughout the whole job, turned up whenever he said he would, and kept in constant contact. Really honest (I happily left him unattended in my property). Customer service was excellent, nothing was too much trouble. 10/10 would recommend.

Gareth arrived early, identified the issue and was really prompt in fixing it. He was very clear in explaining what the issue was and showing me how he fixed it. We also had another issue in the bathroom and he was able to identify it and give tips on how to manage it in the future. I would definitely recommend him and have saved his number in case of the need for future work. His also provides guarantees for his work which gave me alot of peace of mind. Thanks again!

Restoration & Refurbishment- 28 Dec 2015
I did quite a bit of research before choosing Battersea Builders. They didn’t come in with the cheapest quote but I never base my choice on price alone. And it wasn’t miles above the other quotes I got. Instead, I chose them because they ticked a lot of boxes including a) good independent reviews, b) a dedicated PM, c) qualifications, d) quick responses, e) a decent website etc. Overall, they did a fantastic job. The quality of the work and finish is really good. The PM, Tommy, was really helpful throughout and the team was very polite and conscientious. They were also on site every day as promised and didn’t play that old builders trick of getting the job and then going offsite to secure another job elsewhere (resulting in the deadline being missed). Was it perfect? No, but then not many projects are. I have a few minor comments including the fact there was a misunderstanding about the quality of bathroom cupboard I needed so the original quote was insufficient and costs had to be increased half way through the project. Despite this issue, Tommy did his best to keep the extra costs down. One other niggle was that I asked them to keep all the manuals and instructions for all the fittings but they threw them out. Not a big deal but quite annoying. Overall, it wasn’t cheap but I would use them again because the work was done to a high standard and the team were a pleasure to work with.

★★★★★ Highly Recommended! I had an existing 3-bedroom rundown property and contacted multiple builders before meeting Director Mr. Q Nawaz. From our first meeting, I was impressed by his ideas and the fact that Grand Designs could provide all services in-house. Initially, I proceeded only with the planning application to see if what he promised was possible—and YES, he delivered! My application was approved as he assured me. Seeing this success, I entrusted them with the entire construction project, and Grand Designs completed it within just 6 months, despite the challenges of COVID-19. Not only did they build my project, but they also added significant value to the development. I’m proud to have worked with them, and their exceptional work on my St Albans development is now featured in their portfolio. Within one year, the value of my property increased by £500,000—a testament to their expertise! Extremely professional, highly skilled, and very reasonably priced. You don’t need to go anywhere else—Grand Designs is the complete package!

Architecture- 20 Nov 2016
This is the first time we are carrying out an extension work at our property. Sean worked with us from a very early stage, prepared the drawings, coordinated with the council and ensured that we received the building approval on time. He was always available to advice us (when requested) on design challenges, choosing installers and material choices which we found very helpful. We are very happy with his work and thoroughly recommend him.

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!
