Speaking after the ceremony, held in Manchester's Hilton Hotel, Dualchas architect Alasdair Stephen said,
"We are delighted that it was recognised that work which is relatively modest in its scale and budget, can compete with some of the country's more visible projects when it comes to quality and importance.
"With many predicting a recession and money being tight, we hope that we can show that good quality design is still a valuable investment for the future."
