“Another magnificent job completed by D L Rhodes building contractors! The extension was a complete success and the school will benefit tremendously. As expected Paul and his team were easy to work with from beginning to end and the quality of their workmanship has been superb! The timeline presented to us at the start of the project was kept to and all the health and safety requirements were followed to precision. The workforce were professional and courteous at all times. I would absolutely recommend DL Rhodes to any school considering building works!
