Jack built a brick buttress to structurally support my garden wall. Originally I was going to rebuild the entire wall, but Jack’s advice to build a buttress saved me a lot of money! The job was done quickly, affordably and to a high standard. Would highly recommend.

Really pleased with our built-in bedroom storage. The quality of the work and the finish is excellent. Communication was great throughout, with quick responses to messages, and he was very flexible, happily taking on a few extra jobs around the house and responding to feedback as he went. Would definitely recommend!

Bathroom Fitting- 22 Sep 2025
I recently had my bathroom completely renovated by Zsolt and Mario and the experience was outstanding from start to finish. They were professional, punctual, and incredibly skilled—nothing was too much trouble, and their attention to detail was second to none. One of the highlights of the project was the walk-in shower they installed, It’s beautifully tiled, and gives the bathroom a sleek, modern feel. They kept the workspace clean, communicated clearly throughout. Zsolt clearly take pride in their work, and it shows in the final result. The bathroom looks fantastic and feels like a real upgrade to the home. I wouldn’t hesitate to recommend them to anyone looking for trustworthy, high-quality builders. Thanks again, Zsolt and the rest of the team, you’ve done a brilliant job.

Extensions- 13 Feb 2025
Shami and his team had been fantastic from start to finish! Before hiring his team he showed me around a house his team built, which was amazing to see. His communication was excellent throughout the progress of my renovation and very reassuring. Even as I had made changes to the build, he was very helpful in planning and adjusting to my needs. His team had built a single floor rear extension, including a new kitchen, bathroom suite, full electric rewire and plumbing from scratch. Also, comparing his team with six other builders, he had one of the most competitive quotes for the build. Post finishing the job, any issues I had were resolved immediately putting me at ease! I would definitely hire Shami and his team for any future jobs.

I've used Facundo's team to install a new shower, including wall and floor tiling, massage jets, and concealed shower equipment. Facundo was the person we dealt with at all times, although someone else was assigned to do the job. The quality of the work and finish is extremely good. I was also impressed with Facundo's professional attitude at all times, being very polite and respectful, as well as proactive in addressing any potential issues affecting our planning and execution. Highly recommended.

Windows & Doors (uPVC & Metal)- 13 Jun 2024
Job done promptly and within the budget required. The window was put in place so quickly I didn’t have a chance to wipe the dust of it before it went in! Would suggest the fitter carries a cloth with him to wipe fingerprints and bits off the window before installation but really a small thing considering. Overall very happy with the job done. Thanks.

A really excellent set up of builders. Peter was great in evaluating the work and what we needed done. Sue was clear in her communication on costs, and then execution of the works by Taras and his team was superb. The extension was built in fantastic time-frame, and the end result is great. The work-ethic of the builders is what really makes them so good. They are on-time every day, and relentless with working hard each day.

I looked at 5 quotes and was so happy to have chosen Elvis and his highly experienced team. They did an excellent job of building a new 11sq meter garden rear extension. This was a bit complicated project because it’s a listed house. Elvis and his team were hardworking, always responsive and came up with great solutions when necessary. I am very pleased with the high quality end result. I would use them again and can't recommend them enough! Great job done

Painting & Decorating- 6 Oct 2022
Very pleased with our choice. We initially got four quotes from different builders, most of them were terrible at communicating apart from Alfred. He was very easy to work with, responsive and very careful with our brand new house. His team was hard working, tidy and fast. They completely renovated our garden from removal of old decking and gravel to setting up new fences, levelling and turfing the ground. They also removed our old kitchen, partition wall and carpet, as well as did jobs like plastering, building a wall and set up lights and shelves. We’ll surely have him back soon to work on other jobs.

What experience do you have with similar extensions in Newington?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Newington extension builder’s ability to deliver a result that meets your expectations.
