Ballymena's Ecos Environment Centre opened in August and it is another award winner. It is powered by wind and solar energy and is a champion of recycling. It is also a rare example of a piece of millennium architecture that has won universal praise. Another winner is the Young People's Centre in Warrington, which is inextricably linked to events in Northern Ireland. It was built in honour of Johnathan Ball and Tim Parry, the two boys killed by an IRA bomb in 1993.
Young people can come and enjoy simply being together - and learn a bit more about peace.
The centre has a cyber cafe, a shop that schoolchildren can run themselves, an art room and a residential wing for visiting children from war-torn countries. The awards presentation will be made on Thursday at the Science Museum in London.
