I had the pleasure of working with Romeo and his team on my kitchen renovation, and I couldn't be happier with the results! From start to finish, his work was great. The kitchen looks fantastic, and they even finished the project ahead of schedule! Romeo and his team were very professional, always on time, and always kept me updated on the progress of the project. They also kept the flat clean and tidy every night, which made it much easier to live in the flat while the project was being done. I highly recommend them to anyone looking for a kitchen renovation!

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!

Extensions- 23 Aug 2023
On schedule and to budget, Ibrahim and his team from Triada Building Ltd delivered a very high standard on this project. Despite poor weather (Summer of 2023) and some issues with 3rd party contractors, access for concrete pour, skip delivery etc. his team worked each stage of the project to plan keeping me informed and showing great level of craftsmanship. I was after a simple workshop build that would compliment our house and he did not try to over sell options I wasn't interested in. Very happy with the result, and would recommend. Thank you.

This was a major piece of work. F&G Design and Build created a stunning new storey to the house. The roof was renewed, new windows inserted back and front, plus a shower, toilet, cabinets and basin in adjoining bathroom. Special mention needs to be made of the extension to the stairway. They copied the original design to perfection (much admired by all those who have seen it). They also refurbished my kitchen to a very high and beautiful standard. They were always friendly and approachable and totally reliable. An absolutely brilliant team, and a pleasure to work with. And they finished the job on time!

I had my double side and single rear L shape Extension which had kitchens and bathrooms with bedrooms. It was turnkey project and didn’t know them before but they are Pro Contractor as they got all planning permission approved with structural calculations. They completed work in time with high standard quality and regulations and got my certificates from council. I would recommend them as Pro builder all the time.

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

An extension builder in Furzedown 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.

What experience do you have with similar extensions in Furzedown?

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