The relocation of the Royal College of Organists to Birmingham has been delayed because of a "funding gap".
The RCO has already secured 90 per cent of the £8.23 million for the project but needs more time to find the remaining funds before work can start on the restoration of its new home, the Grade I listed Curzon Street station in Digbeth.
The upgrade of the historic building was due to have started by this summer and completed by the end of 2006.
However, the delay looks set to postpone the launch date for the prestigious relocation project.
The scheme is being supported by the Heritage Lottery Fund, Birmingham City Council, the European Regional Development Fund and regional development agency Advantage West Midlands.
College president Peter Wright said: "Thanks to the generosity of all our funding partners we have about 90 per cent of the funding in place for this magnificent project.
"However, this does leave a funding gap of just under £1 million to meet.
"This is a project which has profound implications for the college, for the organ and organ music, and for Birmingham itself and in those circumstances we feel it is right and prudent to defer the commencement of work until we are sure where the extra funds will come from."
Mr Wright said the RCO would, in the meantime, continue to catalogue the British Organ Library, which contains, among other material, manuscripts for organ design and choral works which date back to the 16th Century and sheet music by Mozart and Mendelssohn.
Council leaders last December approved a £1.3 million grant for the project together with a 125-year lease to the RCO at a nil premium.
At the time, cabinet members were warned by Eastside director Richard Green that a funding shortfall could endanger the success of the project.
He recommended the council raise its support to a total of £2 million in a "full and final offer".
The scheme includes the library, offices, a restaurant and a new 270-seat auditorium which will house a specially- commissioned £750,000 organ from Swissbased Goll Orgelbau, which will form an architectural feature at Curzon Street.
The RCO ran into problems with storage and access at its former home in Holborn, London, and is currently based at Millennium Point in the city.
The relocation of the college is seen as a major coup for the city and a vital part of the Eastside regeneration project. ..SUPL:
