"This complex project was successfully completed to a demanding time deadline. The scheme was delivered to budget to extremely high standards. We are delighted with the facility in terms of overall appearance, the facilities provided and ongoing energy savings. CBG provided excellent support throughout the design stage, implementation and during a “soft landing” when the project was handed over."
