Loft Conversion- 11 Jun 2026
We recently completed a loft conversion with Dean and his team at Blakeon, and I couldn't be happier with the result. The workmanship has been excellent throughout, and the new loft space has completely transformed the house while feeling fully integrated with the rest of the property. What really stood out was the communication, reliability and flexibility. As the project progressed, I refined several design decisions before they were finalised, and Dean was always patient, accommodating and willing to discuss options. The project included a number of additional complexities, all of which were handled professionally and pragmatically. I also remained living in the house throughout the build, and the team were consistently respectful, considerate and easy to work with. I would have no hesitation in recommending Dean and his team and am already discussing future projects with him.

Extensions- 12 Jun 2026
highly recommend Acl brickwork for any major building work. They recently completed a double extension and a full driveway replacement for us. From the initial quote to the final handover, Ashley and his team were fantastic to deal with. The brickwork on the extension matches our original house perfectly, and the finish inside is flawless. The new driveway looks incredibly sharp and has massive curb appeal. Major construction can be stressful, but they kept the site tidy, stuck to the agreed timeline, and were polite and respectful of our neighbours. A huge thank you to the whole team for a job well done!

Extensions- 31 May 2023
We hired Anthony back in January after he gave us in what we thought was a very good quote, Anthony was quick to respond and he was very thorough with the job moving forward, he took over from another builder who didn’t do a very good job, and Anthony took over and we are delighted he did. Anthony and his team were always on time, clean and their eye for detail is excellent. They would always talk us through the next steps and if we had any questions he would always re assure us and give us brilliant advice, I couldn’t recommend Anthony enough he has saved our house and made it a home again, if anyone is looking for any building work anthony is your man, top man anthony thank you very much 👍🏻
