Tate St Ives has decided to review Jamie Fobert's proposed extension to its galleries - so that it can secure more funds for the scheme.
The project is now facing a 12-month delay that officials claim will allow Fobert to re-analyse the scheme.
The gallery made the call to potentially revamp Fobert's controversial proposals shortly before Christmas, to allow the project to be eligible for more cash from the European Union.
An extension to the scheme's timetable will mean that it will no longer be able to tap in to an existing European 'Objective 1' funding programme that finishes this year.
But the project team will be able to bid for a successor funding programme that could provide more cash for the scheme.
Crucially, the delay will also allow the architect to make a fresh attempt at appeasing local residents, who have rallied against the development, replacing a car park in the congested West Country town.
According to the Cornwall County Council's special projects co-ordinator Frank Chapman, the local authority has used this 'breathing space' to review the project.
Chapman said: 'We're drawing breath, reviewing things across the board, to make sure that we can optimise what we can achieve.' by Rob Sharp
