Judges’ Comments

“This is a clear winner, showing how retrofit and refurbishment can, with determination and skill, achieve extraordinarily high environmental standards.  All parties: the client, architect and contractors are commended for not only setting but maintaining the vision for an exemplary and game-changing approach.  The aim from the start was to feel normal while being deep green.  The process has been recorded and operating standards are being closely monitored with the aim that others can both copy and better it.”
