Extensions- 22 Dec 2025
We contracted JMD for a detached house project to demolish an old 1970s extension & rebuild larger 70sqm extension, an outside terrace patio and remodel some of our internal ground floor setup. Project started in Feb2025 and JMD made super quick progress on the build during the dry spring months. We had to pause JMD due to our timelines which they were fine with and finally completed end-to-end by Oct2025. What makes JMD standout for us was their team of employees – they don’t use too many contractors, most of their team are employed by JMD and are a loyal hardworking professional squad. Liam, Mark, Chip, Ross, Zac and the rest – all top class! We had some additional projects and requirements mid-project, JMD provided good pricing along the way which were all totally fair and priced as incremental add-ons. YES – there are always bits that could be better, but JMD did an excellent job on the whole. Site left clean, tidy, complete and all post project snags dealt with! THANKS JMD!

Extensions- 30 Dec 2020
I have only got positive things to say about this project - we are extremely happy with both the end result and the overall process. This was a big project for us, involving an extension of our kitchen and conversion of our garage into an office, to transform the entire ground floor of our property. It involved taking down two external walls and three internal walls, requiring the fitting of 3 steel beams. We had underfloor heating installed throughout and a bi-fold door extending across the whole back of our property. Zurab’s team, AZ Renovation, did everything – laying foundations, building new walls, electrical wiring, plumbing, plastering, tiling, painting, kitchen fitting, the whole works. Zurab, his main builder Mikheil and his team did an exceptional job and it was a pleasure working with them. They were friendly and helpful right throughout the project, listening to our ideas and concerns and helping us make the right decisions. Their attention to detail was excellent and they did all of their work to a very high standard. We are so happy with our new kitchen/ living area and it is an amazing space for our family. We would have no hesitation in recommending Zurab and his team for large projects like house extensions (or anything else for that matter). In fact, we have booked them in to come back next year to help us remodel our garden and outdoor area!

AT Line Construction built our extension and worked on the remodel of the inside of our flat. We are extremely happy with the results. Adison and his team are very professional and friendly. They were able to deal with any changes and problems that came up quickly and sensitively. Part of the build was to renovate a small disused swimming pool - this was a tricky job, and they were able to help us creat an amazing pool. We would definitely recommend them.

Agim completed a ground floor extension for me in 2025 and I would not hesitate to recommend him for similar work. The quality of the work was excellent and the team worked tirelessly for months to ensure it was completed on time and for a reasonable price. Agim was able to adapt quickly when any unforeseen problems occurred, always clearly communicating possible solutions to help keep the project moving. Having people in your home can be difficult but Agim is very respectful and considerate, making sure to put our needs first. The results are fantastic and Agim continues to help snag any minor issues that come up. I couldn’t be happier with how things went, testament to his professionalism. Thanks Agim for all your help on this project.

I recently had my whole kitchen renovated, and I couldn’t be happier with the results. The team was professional, skilled, and incredibly organised from start to finish. They arrived on time every day, kept the workspace tidy, and communicated clearly throughout the entire project. The quality of workmanship is outstanding — from the cabinets and tiling to the plumbing and electrics, everything was completed to a very high standard. They paid great attention to detail and always made sure I was happy with each stage before moving on. What impressed me most was how smoothly everything went. Any small issues were dealt with quickly, and the team was friendly, respectful, and easy to work with. My new kitchen looks amazing, and the whole project was finished on schedule. Highly recommended — a reliable and talented building team that delivers excellent results. I would definitely use them again for future renovations.

An extension builder in Belmont 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?

What experience do you have with similar extensions in Belmont?

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

How long will the extension take to complete?
