The Scottish Government has said there has been no increase in the cost of building the V&A at Dundee, despite investing another £20 million in the project.
Finance Secretary John Swinney announced more than £60m of funding to help develop Dundee’s waterfront last week.
Of the £63.8 million granted to Dundee, £20m has been earmarked for the development of the Kengo Kuma-designed V&A.
The money comes a year after the Scottish Government was forced to give another £10m to the project after costs ballooned from the initial expected price tag of £45m to £80.1m.
A spokeswoman for the Scottish Government said: “The capital cost of V&A Dundee has not increased.
“The additional package… includes the £12.6m remaining funding requirement for V&A Dundee and reflects an apportionment of the council’s assessment of the potential wider financing costs associated with the overall central waterfront development.”
Both Dundee City Council and the V&A Dundee have maintained there has been no further increase in the cost of the building, which will be the centrepiece of the planned £1 billion waterfront redevelopment.
Construction work on the museum began in March and the completed project is scheduled to open in 2018.
The £63.1m funding agreement is only the second of its type in Scotland following an £850m agreement to redevelop St James Quarter in Edinburgh.
Under the terms of the deal in the capital, £61m of public money is being used to upgrade infrastructure at the east end of Princes Street.
Known as a Regeneration Accelerator Model (Ram), the investment is offset by business rates and overall gains to the economy.
Money will be paid to Dundee over 25 years and is dependent on the council achieving a set of specific agreed aims.
A review of the cost of fitting out the £80.1m V&A at Dundee is now under way but is not expected to affect the museum’s overall budget.
