Extensions- 4 Aug 2019
Very constructive input throughout the whole process. We were given a clear idea of timescales for every step of the build, what to expect and how they would minimise disruption to our household which was all done effectively as promised. For the beginning he made clear that the process would allow us to still have a family home running (almost) as normal for most of the build, which was really helpful with our young children! Baz would always answer any questions and welcomes feedback. He would be flexible and find ways to work around problems to ensure the design was achieved and did so beyond our expectations. The build was completed to schedule and to a high standard. He would work with you to make sure everything was done properly and around schedules you have with other services if you are using separate glazing or kitchen suppliers as we did. We’re very happy with choosing Smiley building services and would definitely use again. All his staff are friendly, polite and considerate. Friends and family who have seen the work on our house have already asked for Smileys details for their own build work due to the great finish.

Extensions- 21 Jul 2025
I recently hired AK construction to build an extension on my home, and I am beyond impressed with their work ethic, flexibility, and outstanding customer service. The extension was built to the highest standard—flawless craftsmanship, attention to detail, and seamless integration with my existing home. The team was punctual, tidy, and respectful throughout the project. What really stood out was their willingness to help, even beyond the contracted work. When I had some DIY tasks, they offered advice, lent me tools, and even stepped in to assist where they could—despite not being obligated to do so. Their kindness and professionalism didn’t waver, even when I declined additional quotes for other work. They stuck to the timeline and budget with no surprises. Communication was excellent, and they treated my home with care as if it were their own. I can’t recommend Ali and AK Construction enough—they’re trustworthy, skilled, and genuinely care about their clients.

New Builds- 7 Jun 2022
Sohail worked closely with me on this project. Providing detailed costings, work schedules and build timelines. Filling my knowledge gaps with his extensive experience he was able to assist over and beyond what I expected from him. Unfortunately due to circumstances out of my control this development project didn’t go ahead. However when the next opportunity for a new build comes up I will definitely be using Rose and Stone. I did have another job going at the time where the other builder badly let me down and left me with a big problem on my hands…. Sohail and his team stepped in and took on the project. The team finished the job exceptionally well, which was a full on top to bottom conversion, some internal reconfigurations and with the addition of a loft and new downstairs WC. The workmanship and overall quality of the job was excellent. My wife is over the moon with the results, taking the house from a three bed one bathroom to a four bed 3 bathroom house. We would definitely recommend Rose and Stone for this type of extensive refurbishment/loft conversion work and look forward to working with them in the future on bigger development projects.

Carpentry- 15 Aug 2025
I would 100% recommend John and his team. We have been really unlucky with 3 other builders taking off with our money and not completing the work. John is very professional, took on someone else’s mess and done a brilliant job. We wanted exposed oak rafter detail and the team done an excellent job. John is very good at problem solving on the spot when there are issues, he is very approachable and keeps you updated with the progress throughout the job. What he has been good at is also talking through different options with us before doing different sections of the work and he does not take short cuts. If you need excellent honest builders John is your guy! We will get the decorations done and post the end product.
