I received quotes from multiple builders to build a garden office, and choose Teodor as he provided the best quote. His workmanship is top quality and he built me a fantastic garden office which I am enjoying immensely. Teodor was very professional and reliable, keeping me involved throughout the whole project.

Quality Builders completed a remarkable domer and loft conversion for us on 2/10/2023, and we couldn't be more pleased with the results. From the outset, their professionalism and attention to detail were evident. The initial consultation was thorough, and they took the time to understand our vision for the space. Throughout the project, communication was excellent, with regular updates on progress and any necessary adjustments. The craftsmanship displayed by Quality Builders was exceptional. Every aspect of the conversion, from structural work to finishing touches, was executed with precision and care. Their team of builders and contractors demonstrated expertise and skill, resulting in a finished product that exceeded our expectations. Not only did Quality Builders deliver on time, but they also adhered to budgetary constraints without compromising quality. Their transparency and honesty throughout the process gave us peace of mind and confidence in their abilities. The transformation of our space is truly remarkable. The addition of the domer and loft has added both aesthetic appeal and practical functionality to our home. The new space is light-filled, spacious, and seamlessly integrated with the existing structure. Overall, we cannot recommend Quality Builders highly enough. Their commitment to excellence, attention to detail, and professionalism set them apart in the industry. If you're considering a home renovation project, look no further than Quality Builders for exceptional results.

Bathroom Fitting- 6 Jun 2020
The bathroom was refurbished from top to bottom even changing the location of basin, toilet and shower. One worker employed by AGStar Ltd did the entire job including floor and wall tiling. The worker cleaned up the stairs and the hall everyday before finishing for the day. When requested to carry out additional small jobs, not part of the contract, the worker always obliged. The refurbishment of the bathroom was carried out to a very high standard by just one worker and in short period of 10 days. I would recommend this company for all building work although a little pricey!

Norbi is an exceptionally talented carpenter. He was the team lead on our major building project when we restored our Victorian house over an 18 month period. All his work was superior, from replacing ceilings and ceiling roses, to laying the new herringbone floor with electric underfloor heating. He was always polite, well mannered, and respectful. Norbi takes pride in his work and genuinely cares about the finished result in your home, a rare quality amongst many. We cannot recommend him highly enough.

Conversions - General- 28 Jun 2026
We recently had our detached single garage converted into a fully usable room by Agron and his team, and we couldn't be happier with the result. The project involved replacing the garage door with matching brickwork, raising the roof, installing new windows and a door, insulating the garage, plaster boarding and skimming throughout, and rendering and painting the exterior. The work was completed to an exceptionally high standard. Agron and his team were fantastic from start to finish. They were incredibly friendly, professional and hardworking, completing the project quickly without ever compromising on quality. Communication was excellent throughout, they kept us updated on progress and always made sure we were happy with how the project was proceeding. They were also very accommodating and happy to adapt to any requests or changes we made along the way, making the whole process stress free. The attention to detail and pride they took in their work really shows in the finished result.

Extensions- 15 Oct 2020
DPS were superb from start to finish. They were hired to build a single storey rear extension in North London including a new kitchen and bathroom fit. I met Ralph on site along with a number of other builders, Ralph was highly knowledgeable and clearly explained what was required with practical solutions. DPS clearly scoped out the timeline and cost for each stage of the build and kept to this. They completed several agreed extras throughout the job. Communication with Ralph and the whole DPS team was first class throughout. I own a number of rental properties and can comfortably say DPS are the best builders I've dealt with, I cannot recommend them highly enough, they will be my first port of call for future work.

Conversions - General- 6 Apr 2010
After being let down by our previous builder, shortly before work was due to start, we were informed about this website, and somewhat hesitantly posted our garage conversion and kitchen renovation onto the site. After obtaining quotes from 3 builders, we decided to hire Nick cos of his straightforward and honest attitude to the job. We spoke with a couple of people that Nick had previously done work for, and they were very complimentary, so this just confirmed our decision to hire Nick. We have never undertaken any extensive building work before and were therefore nervous about the work starting, however I can honestly say that Nick was absolutely fantastic from start to finish of the project. Nick and his team were extremely hard working (finished much sooner than we expected), they kept the house as clean as possible when completing such works, and were generally an absolute pleasure to have around the house. Nick's craftmanship is exemplary and was always there to discuss any changes, extras or cut backs when not required. I would not hesitate in recommending Nick to anyone, safe in the knowledge that I know he would do an exceptional job, in fact more than three people have already asked for his details upon seeing the great job that he has completed here!! Thanks Nick for everything!!
