Extensions- 7 Jun 2026
Zilvinas and the team at Innovate Builders were outstanding from start to finish. We hired them to build our two-storey side extension. Zilvinas was open, professional, and fully committed throughout the project. He was always available to answer questions, offer advice, and guide us through each stage of the build. His team worked hard and delivered a high-quality finish, all while keeping the project on schedule and within budget. As this was our first major building project, we relied heavily on Zilvinas's expertise and guidance. His knowledge, practical advice, and problem-solving skills were invaluable and made what could have been a stressful experience feel smooth and manageable. We are absolutely delighted with the result and would not hesitate to recommend Innovate Builder. As I said it was our first ever big project, we had heard many horror stories but are so grateful to have found Zilvinas and his team.

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.
