The winner of the prestigious Royal Institute of British Architects' Stirling Prize is due to be announced later.
Judges will select the winner from a shortlist of six buildings which range from a new wing for a derelict castle to a revamp of an inner-city housing estate.
Members of the public were given the chance to have their say by voting on the BBC website, choosing Astley Castle in Warwickshire as their favourite.
