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.

Landscaping- 4 Oct 2024
One word to define this 'company' COWBOY builders. Numerous issues one after another. Had to get 2nd/3rd opinion on their work to make sure I wasn't being fobbed off. Conducted loads of research which meant left being uneasy especially as a large chunk of payment was made after only 1 day of work when in fact payment was due end of completion. 1- Underestimating material costs 2- Slabs off the walkway coming loose within 2 months of being put down 3- Ignoring attempts of rectifying the flawed job 4- walkway was meant to be clear of grass and strictly shingles but grass/weed still appearing. 5- Forgot to state ground levels would be raised then creating a lie saying I had been told 6- denying and ignoring the obvious Wouldn't trust the reviews being left here and definitely wouldn't use or recommend them to anyone. Have decided to give up on trying to get them to fix their shoddy job and find someone else to fix their mess Correction - you was aware & agreed with mat delivery

Groundwork & Foundations- 26 Feb 2025
I hired John to build a concrete base for a garden building installation and he did a great job, resulting in follow-on work for him laying a new Indian sandstone patio in front of the building, which he also did to a high standard. After receiving several quotes from different firms, I selected John because he asked the right questions, clearly thought about the solution and was interested in ensuring the result was the right one right for me. He's a lovely bloke and a pleasure to have working here. He works on his own and for the most part keeps himself to himself, wasn't fussed about tweaking the scope here or there as the plan developed and kept the place pretty tidy throughout. I will be using him again for sure, so I wholeheartedly recommend John for any work you're considering hiring him for.
