The Job was to extend the rear of the house on the ground floor, open up the kitchen and reception room into one open plan living area, to refresh the rest of the house which included new plaster skim, doors and frames and to fit new bathrooms and kitchen as well as an rewire on the whole house and the construction of a retaining wall in the garden to accommodate the extension. Florins team were excellent from start to finish, the whole project was completed in record time to a very high standard. The 10 weeks turnaround was incredible, we were very happy that Florin was always here at the property or on the end of the phone throughout the process, his professional advice and smart ideas made for a smooth transition from room to room. The team were very hard working, polite and knowledgeable, these guys worked very hard and very quickly which was amazing to see and I was very grateful we were able to move into the property earlier than planned which even saved us money on the temporary accommodation we had! Can’t thank you enough Florin, any small issues we had were dealt with quickly and smoothly, I love the house, the level of work and would 100% use Florin and his team on my next project!

Latest review:
I was planning an extension to my kitchen, which included a complete refurbishment and the addition of a shower room. I also needed somebody to coordinate all aspects of the project, including recruiting the right resources for the building work, electrics etc. I was extremely pleased that Bull & Chisel were recommended to me. From the start, Bryan and Warren gave me the confidence that they were able to complete the project to my satisfaction. They were happy to continue working with me throughout and they liaised effectively with partners they brought in at key stages to ensure that each task was completed to my satisfaction. As for their own work, I cannot fault them. There are always unexpected challenges that arise in these types of project. Bryan & Warren consider these very carefully before providing a solution. They pay close attention to detail and that has resulted for me in a super new space. I highly recommend Bull & Chisel and have already asked them to sign up for more projects in the near future!

What experience do you have with similar extensions in New Southgate?

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