I am an experienced and fully insured builder. On average I and my team build and renovate 5 extensions per year. Our current or old clients are always ready to share positive feedback about our work. We work off the ready plans which are usually prepared by the clients themselves and approved by the local authority. As of now (30/03/2023) my availability to start the new project is late April or early May. Please get in touch and I will be happy to assist.

Extensions- 4 Aug 2020
On a cold November evening, Tony and his team turned up to provide a quote and within a week this was received. The quoted price came in the middle of the pile, which was a good start and aligned closely to the ballpark figure I'd received from a friend who was also in the trade. We then visited a site they were finishing off, and Tony had the confidence to ask us to speak to the client without him there and they gave us the confidence to proceed. They started in January 2020 and rapidly moved through the works and engaged closely with my architect, Structural engineer and building control and proceeded based on their recommendations strictly. We lived in the property as build progressed and the team ensured that the site was secure every evening and we were safe. As COVID-19 hit and we went into Lockdown, the team continued to come and work (we were separated from them as the house was boarded up) and the only challenge was getting supplies. Tony scoured all over London, picking up items as best as he could and work continued. Once they'd broken through into the old part of the house they continued to progress rapidly and showed utter professionalism. The team lead's attention to detail is impressive, and he gave great recommendations on what would be the right approach when we were laying out features such as window sizing and lighting. The standard of work is excellent and I would highly recommend them.

Extensions- 5 Oct 2022
I am very pleased with the work Josh and his team did in building my rear extension. They were a friendly and hard working bunch and very respectful of my space. Josh did a great job in project managing the work and making sure things were progressing as planned. Any snagging items were dealt with promptly. I would hire them again if required and recommend them to anyone who wanted to have building work done.

Extensions- 25 Aug 2021
Having had bad experiences in the past with other builders, this time we tried to do our homework properly before hiring someone. We couldn't have chosen a more competent and professional builder! We obviously asked around and had many quotes (some ridiculously expensive, others didn't even seem to understand what we wanted to do) but Sorin immediately impressed me with his detailed and fair quote, knowledge and lots of suggestions (he's the kind of guy that immediately gives you the impression that he knows what he's talking about). We encountered some issues during the works (which is to be expected if you didn't build the place yourself) but Sorin and his team did an amazing job and always gave us regular updates. End result? Work completed on time and a new construction that is exactly what we asked for (plus other things here and there that he kindly sorted while he was on site!)

Isac did an excellent job removing my old dishwasher that was stuck in place and fitting the new one at very short notice as the firm booked in to do the job couldn’t remove it. He even helped with getting a loose hinge secured and adjusting the base board to go back into place. Highly recommended

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

An extension builder in Whetstone 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 Whetstone?

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