The trust which took over Scotland's former national museum of costume has announced it will cease trading in January.
Shambellie House at New Abbey near Dumfries closed in 2013, with its contents transferred to Edinburgh.
A trust was set up two years later to find a new use for the building and it was handed over in 2021.
Shambellie House Trust (SHT) vice-chair, Ann Hill, said it was solvent, but insurance, heating and electricity were too expensive. If a new charity cannot be found to take over the site, it will be sold and the proceeds returned to the Scottish government.
When plans were announced to shut the costume museum more than a decade ago it provoked cross-party political opposition.
National Museums Scotland said that it had taken the decision "with great regret" to shut the facility, which first opened to the public in 1982.
The trust was set up to try to bring it back into use and eventually reopened it as an arts and heritage centre in 2022.
However, the building now faces an uncertain future once again.

Hill said the trust had come to the decision "with great sadness" to cease trading on 10 January next year.
She said they had enjoyed the company of many tutors, speakers, events and pupils over the years and thanked them for their support.
However, she said running costs had risen "spectacularly" which had put "enormous strains" on everyone trying to keep the project working but it had become "simply unsustainable".
The SHT will now look for another charity to take over the building. Any bid would need to be approved by the Scottish government which transferred the property to the trust.
If it is unable to find a new operator, then the house and land would be sold.
'Sorry state'
Hill told BBC Scotland News the building had been in a "sad, sorry state" when the trust took over and it had been struggling almost since the outset to find enough money to look after it.
She said that in recent times things had become even more problematic and the issue was widespread.
"This past year we have seen a lack of money being the most difficult thing for people," she said.
"Even with the quilt show this past week, we've had people that didn't come and phone up to say they were sorry they couldn't come from the likes of Fife or Stirling because petrol was too expensive.
"So it is not just us, it is the whole country that is feeling it and I see more charities winding up than ever before."
She stressed that they were still solvent and did not owe "anybody anything".
