I recently completed the building of an orangery extension (with skylight) to my semi-detached townhouse in NW London. The extension was to be used as a new kitchen while the existing kitchen converted to a living room. I awarded the contract of building the extension to Anthony and I was pleasantly impressed with the quality of work delivered. Anthony Project Managed the entire process from beginning to end and ensured that all my expectations were surpassed. His hands-on attitude to every detail of the work was quite reassuring. I am glad to say that Anthony and his team are very good professionals and they delivered the project on time and within budget, even going over and beyond the original scope of works in order to ensure that all my latter requests were addressed appropriately.

Bathroom Fitting- 21 Jun 2022
We are not entirely satisfied with Ludovic's work. Some of the tiles were not cut to the correct messurement which left big gaps in between. Worse still, the grouting was very messy and did not have a smooth finish. We will now have to get another Tiler to redo some of the tiling work. Overall, it was not a professional job and we are not very happy with his workmanship.

Had work carried out by RS construction recently, was an overall pleasant and stress-free experience, had a dormant chimney breast removed all the way through my property. Which had to be removed due to constant leaks and repairs by previous roofers. Ross was very helpful and knowledgeable throughout the project and his team kept my house and garden very clean considering the work that was undertaken, it has not only freed space within my property but given me peace of mind concerning continuous leaks, which have caused numerous issues over the years. Can't recommend this company anymore , from sale to completion a very professional and helpful service

Bathroom Fitting- 30 May 2022
Mohammed Huda and his builder were professional and quick to attend our job –– recommend! The communication was fast and professional. Mohammed provided a detailed quote (our job had to go through insurance) that is fair and transparent. The builder who came around, Jafa, was very respectful to our things. We were able to trust him from the get-go and had a peace of mind when he was working. He works incredibly hard and is methodical in his process (e.g. painting ceiling first, then walls, so to avoid splatter unevenness). They responded to our requests quickly and fixed things we weren't 100% happy with. The team finished the job ahead of time, and gave us tips for refurbishing in the future. Very happy and highly recommend!

Hard Flooring- 29 Dec 2018
Giuseppe and his team are top level professionals able to give qualified advice and real expertise. In renovating our art gallery, they showed real old-time mastery from the beginning. They not only helped us study the most suitable solutions for the features of our place both for the flooring and the walls painting, but also showed amazing precision and care in carrying out the whole renovation project by applying the renowned knowledge of Italian master masons. While other builders had cursorily told us that any laminate would be good, the one that Giuseppe and team suggested us was selected by considering both the resistance to the clomping and the desired aesthetic result. Also, they adopted all the special arrangements needed to prevent the wood floor from bulging and lifting. They suggested us the type and the colour for the skirting board, making the gallery even more refined. The works were terminated in the estimated time and the fantastic result in terms of elegance, sophistication and safety has been possible thanks to the reliability and attention to detail of Giuseppe and team. We were so satisfied that we decided to hire them for all the other works needed (ceiling painting, walls painting, positioning of the anti UV film in our windows, enforcement and lifting up of the electrical track for the lighting system). All these works were completed with mastery and are still contributing to fascinate all the visitors at the gallery!

Blerim undertook the task of constructing a rear extension to my home, which involved creating additional living space while seamlessly integrating it with the existing structure. The project was quite intricate, requiring meticulous attention to detail and a deep understanding of construction techniques. Blerim's craftsmanship was truly remarkable. He demonstrated an unwavering commitment to quality, ensuring that every aspect of the extension was completed to the highest standards. His precision in measurements, choice of materials, and execution of design elements exceeded my expectations. Throughout the construction process, Blerim exhibited the utmost professionalism. He was always punctual and kept me informed about the project's progress. His communication skills are commendable, as he patiently answered all my questions and addressed any concerns I had. His ability to work collaboratively with me and the other contractors involved in the project contributed to a smooth and efficient workflow. One aspect of Blerim's work that I found particularly impressive was his reliability. He consistently met project deadlines and stayed within the agreed-upon budget. This reliability gave me peace of mind throughout the construction process, knowing that I could trust Blerim to deliver as promised. In addition to the extension, Blerim also transformed my outdoor space with his landscaping expertise. He took my vision for a beautiful and functional outdoor area and turned it into a reality. His landscaping work included planting trees, creating flowerbeds, installing a patio, and adding various hardscape features. The result is a stunning outdoor oasis that I now enjoy daily. In summary, I wholeheartedly recommend Mr. Blerim for any construction or landscaping project. His workmanship is exemplary, his professionalism is unmatched, and his reliability is unquestionable. Blerim's dedication to delivering top-notch results truly sets him apart, and I have no doubt that he will excel in any endeavor he undertakes.

Marius has been doing a great job and put in an extra effort to ensure we were happy with the outcome. I can not recommend Marius highly enough, especially as he managed to fix an issue with the council that we had from someone else drawings. He was patient and very well prepared. Went an extra mile and gave us different ideas/options. He was flexible with timings and most importantly with price. Had by far the best quote and did an exceptional job.
