Sugar sculptor Brendan Jamison is hoping for a sweet response to his gift to Children in Need.
His portrayal of Belfast City Hall - fashioned in sugar cubes - is on the Children in Need auction website.
The artist from Bangor is hoping that it will raise much needed funds for the BBC charity.
"The sculpture was made live on a BBC programme, Out of the Blue. Its retail price in a gallery would be about £1,000 to £1,200," he said.
"In terms of bidding, it is early days. A lot of bidders are cautious. Art collectors tend to wait until near the end of bidding time which, in this case, is Monday 19 November."
Brendan made his reputation from intricate carvings in sugar cubes.
In 2010, he created a replica of the Tate Modern building in London, made to scale, using 71,908 sugar cubes. It is 2m wide and weighs 224kg.
It was commissioned by Native Land and Grosvenor for the 2010 London Festival of Architecture.
More recently, his sugar sculpture of the door of 10 Downing Street found a special niche when it went on display inside the prime minister's house to visiting presidents and leaders.
He also sculpted Henry Tate's Mausoleum in a London project, the Curious sculpture trail.
It went on display at West Norwood Cemetery, London, beside the real building.
He is currently working on a sculpture of an old US spy station in west Berlin. It was built on an artificial hill at Teufelsberg - Devil's Mountain.
"The mound was made out of all the rubble heaped up in Berlin after the war," Brendan said.
"It was piled up into a hill. It was the highest point in Berlin and was used from 1963 to the end of the Cold War. Nowadays people go out into Grunefeld forest for a walk and to see it."
Earlier this year, Brendan Jamison was elected to the Royal British Society of Sculptors.
