The trust's head of awards Vivienne Newlands said that the battle to deliver better British buildings was 'far from won'.
Newlands said that improvements were being witnessed but that far too many schemes were unacceptable.
'The 2005 Civic Trust Award winners are outstanding,' she said. 'There is much good work that we look forward to celebrating.
'However, in the 45th year of the Civic Trust Awards, there are still too many poor projects, out of context, created with little or no reference to the community they are for.
'Excellent projects exist,' she added. 'So why should some communities have to settle for less?'
The 2005 Civic Trust Awards this year will head to the Corn Exchange, part of the Brighton Dome on 7 April.
The location was part of a scheme that one a Civic Trust Award Commendation for restoration work in 2003.
