EXCELLENT Based on 1 reviews Posted on Google MARKO GALLINAJuly 20, 2026Trustindex verifies that the original source of the review is Google. A fantastic experience from start to finish. Jurgen transformed our loft into a bright, modern space with a stunning roof balcony and large glazed doors. The workmanship was exceptional, the project was well managed, and the team was always professional and reliable. The new room has completely changed our home, adding valuable living space and an amazing feature we enjoy every day. We couldn't be happier with the result and would happily recommend G&J Construction to anyone planning a loft conversion or home improvement project.Posted on Google Melania CJuly 16, 2026Trustindex verifies that the original source of the review is Google. We couldn't be happier with the extension completed by Jurgen and the G&J Construction team. From the initial consultation through to completion, the entire process was well organised, transparent, and professionally managed. Our ground floor extension has completely transformed the way we use our home, creating a spacious open-plan kitchen, dining, and family area filled with natural light. The quality of the workmanship is outstanding, with excellent attention to detail throughout every stage of the build. Jurgen kept us updated with regular progress, managed the project efficiently, and ensured everything was completed to a very high standard. The team was always punctual, courteous, and kept the site clean and tidy, making the whole experience as stress-free as possible. The finished extension has exceeded our expectations and has added both valuable living space and significant value to our home. We have already received so many compliments from family and friends and would not hesitate to recommend Jurgen and G&J Construction to anyone considering an extension or refurbishment project. Thank you for delivering such a fantastic result.
