“I had the distinct pleasure of working with Bobby on the complete refurbishment and extension of my family home, and the experience was nothing short of exceptional. The project encompassed a full renovation, both internally and externally, including a new roof and a carefully executed extension. Every element was delivered to an outstanding standard, with a level of craftsmanship and finish that truly reflects the highest tier of the industry. What sets Bobby apart, however, is not only the quality of the work, but his remarkable eye for detail and design. He didn’t simply follow instructions - he elevated them. In many instances, he personally refined and enhanced aspects of the design, resulting in a final outcome that far exceeded my original expectations. Equally important was the pace at which everything was completed. Bobby and his team managed to deliver the entire project in an impressively short timeframe, allowing my family and me to move back into our home much sooner than anticipated. With a young daughter, this made an enormous difference to us, and it is something we are deeply grateful for. Beyond the outstanding professional work, what made this experience truly special was the personal connection we built along the way. Bobby approached the entire project with genuine care, integrity, and warmth. It never felt like just a business transaction - through this journey, we feel we have gained not only a beautifully renovated home, but also a trusted relationship and, I would say, a good friend. Thank you.”

“We couldn’t be happier with the renovation and fit-out of our gym, Intent Boxing, delivered by Finns Group. From project management through to completion, their team were incredibly professional, reliable, and detail-oriented. Even with a tight turnaround, they gave us complete confidence that everything would be done, and done to a very high standard. The quality of the finish speaks for itself, and the entire process was smooth, efficient, and well-communicated. If you’re looking for a company that truly delivers on their promises, we highly recommend Finns Group. Thank you for bringing our vision to life! — Neon & Arron Co-Founders, Intent Boxing”
