Extensions- 1 Sep 2021
I have nothing but praise for Michael and his team. The project was managed exceptionally well and Michael kept us apprised of progress, emerging issues (which were dealt with quickly and with some innovative thinking) and he was honest and candid with our choice of kitchen tile (I think his words were do you want to rethink that colour!). Michael quoted in Nov and started work in the Spring (late Mar) and held his price despite a national increase in the price of materials and reduced availability which he managed admirably. Obviously a man with a good eye; his suggestions for additional works were inspired and they have resulted in a high quality finish. Finally, it is worth mentioning the team who did the grafting! Very industrious, skilled, polite and helpful. Highly recommend Wooburn PM to anyone considering building work. :-)

Extension Builder in Smithfield
My 35 years in the construction industry started as a City and Guilds bricklaying tradesman, moving to the construction of residential extensions/refurbishments and new build properties. I'm now based in Chelmsford and joined My Builder having spent 6 years working in partnership with a London building company. I pride myself on being highly professional, my references and client relationship are second to none. I will personally carry out the build and oversee finishing work to a high standard.

I cannot recommend Rob and his 2 sons highly enough, they have done an excellent job completing the brickwork for our large outbuilding in good time and at a reasonable price. 3 genuinely nice blokes who are hard working and thorough, we wouldn't hesitate to use them again and have already referred for work elsewhere.

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!

What experience do you have with similar extensions in Smithfield?

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