Plastering- 26 Jun 2016
We hired Manu and his team to plaster our summerhouse, relocate two radiators and fit a new bulkhead ceiling in the lounge and install LED tape. He was knowledgable, professional and considerate and I highly recommend Manu and his team. Not only did he understand the project for the bulkhead, but he came up with another suggestion which we went with, and friends and family agree looks amazing. The finish on the plasterwork is perfect and Manu and his team worked hard and even left the summerhouse cleaner than when they started! It is great to work with a team who pay such attention to detail, listen to the client and get the job done to a high standard. It was a risk to go with Manu as he didn't have any feedback when I hired him. I actually got him to quote so I could compare prices with someone else I had in mind to do the job, but when I met Manu I felt he would be the better person to do the job as he listened and understood exactly what I wanted and so I ended up hiring him instead. I wouldn't hesitate to hire him for any future jobs. Thank you Manu and team!

Conversions - General- 11 Sep 2026
I am delighted with my new cast iron Victorian air bricks with grills! Jacek took the old ones out and inserted the new ones. The job is extremely neat and the area left completely immaculately. A few neighbours have taken his number for more work. You will find Jacek extremely polite and amiable, professional, hard working and very knowledgeable about his particular trade. His price was competitive and I would have no hesitation in recommending him. I will be hiring again for other structural work. A great professional find!!

Akash made sure the job was complete exactly how he said it would be, he provided reliability during the installation of our kitchen and answered all questions very professionally. The builders were well aware of the conversations my mother and I had with Akash and so put our mind at ease. The installation itself was very quick (the tear down was very much completed in a few hours) and installed over the weekend. They were very hygiene aware and set up a cover between the kitchen and the rest of our house and didn’t disrupt our home living. They cleaned up before they were gone to very high standards without us even asking them too, all I’m sure is due to Akash’s excellent organisation skills.

Extensions- 5 Sep 2019
The builders did an incredible job refurbishing my house. For my house I wanted to break the internal wall to create a bigger living room and also for them to refurbish the toilet. In the beginning they’ve set a period when everything will be done and they’ve stuck to it so they are trustworthy. Seeing the progress, I could definitely tell that they were working incredibly hard and I know that they have been working long hours to ensure that they manage to finish it within the timeframe that they’ve set. I would definitely recommend them.

We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.

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.
