Noli Antzara

Extension Builder in Bethnal Green
I’m Noli Antzara, a North London tradesman with 37 years of experience. I started working alongside my father at 18 and have spent my working life developing my craft. My main specialities are tiling, paving and brickwork. I also take on bathroom and kitchen tiling, slabs, garden work, blockwork, extensions and painting. Whether it’s a small repair or a larger project, I give the same care and attention to the finish. I prefer to visit the property, listen to what you want and provide a clear quote before starting. Depending on availability, I can often begin within one or two days. I’m based in North London and can travel approximately 60–70 miles for the right job. I know that inviting a tradesman into your home takes trust. I treat every property with respect, protect the areas I’m working in and keep the space as tidy as the job allows. I communicate clearly, take pride in the details and want you to feel comfortable raising questions along the way. After 37 years, I still care about improving and doing work I’m proud to put my name to. My aim is simple: to deliver a quality finish and leave every customer feeling that their home was in good hands.

Tiling- 6 Oct 2026
I couldn’t recommend Noli highly enough. He was incredibly friendly, professional and reliable from start to finish. His quote was very competitive and included all the materials. After seeing the fantastic job he did on my front garden, I wish I hired him before. His attention to detail and quality were impeccable. I’m genuinely grateful for his excellent service and have no doubt that Noli will be my first and only choice for any future projects. HIGHLY RECOMMENDED!

We needed a rear extension built with an internal courtyard. From day one when we first contacted Mert to get a quote he was professional and easy to talk to. His quote was good value for money. During the job he and his team were approachable, careful with our property and always easy to talk to and answer questions we had. The work Mert did was fantastic and our neighbours have already gone on to use him. We will get him back again for more work and highly recommend him.

Restoration & Refurbishment- 25 Sep 2025
We were over the moon with our kitchen once Zihni and his team had finished. We had never used this firm before but we will definitely be using them again for future projects. Zihni is calm, knowledgeable, and went over and beyond in helping us not just complete our kitchen project, but in helping us move into a new home smoothly. We are also really appreciative of the rest of his team, as they were all so serious, professional and perfectionists. Zihni's communication was probably the single reason why the completion of our kitchen was such a success.

Decking- 29 May 2020
Started on time and completed the decking extension & renovation to a high standard. Ensured that small details like cuts around poles etc, were finished properly and not left with gaps. Next time I would confirm that clearing rubbish is part of the quote, but highly recommend Przemek for quality finish.

Not only was Ian's quote to do the loft conversion very reasonable, he was very reliable, tidy & very helpful when we had a difficult situation. The work was done in a quick time, when he said he was going to be on site he was, at no time did he let me down. The standard of work was excellent, I would recommend Ian & wouldn't hesitate to use him in the future.

What qualifications and experience do you have as an extension builder in Bethnal Green?

An extension builder in Bethnal Green should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Bethnal Green extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Bethnal Green?

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 Bethnal Green extension builder’s ability to deliver a result that meets your expectations.
