The Royal Alexandra Children's Hospital won the 2008 Prime Minister's Better Public Building Award.

"The spectacular sweeping steps add drama and beauty to coastal protection - a terrific piece of public space."
"The frank use of raw materials will appeal to the rugged enthusiasms of those using the centre."

"Another delightful bridge over the River Cam - but this one of the 21st century."
