The building, constructed in the 1800s, was originally planned as an orphanage but later became an industrial school for girls.
It was given to the religious order in 1910 by the Duke of Norfolk, whose sister was a Carmelite nun.
The sisters have lived there ever since and because the Carmelites are a closed order – meaning the nuns are strictly separated from the outside world to live a contemplative life of prayer – not much has been modernised.
“It’s quite basic but there is a lot of it,” Mr Goff said.
“The Carmelites’ main drive is for another religious organisation to want it for fair value – that’s their wish and I am in communication with a few.”
However, he said he had also received interest from developers and a leisure organisation.
“We’re just gathering interest and finance ability at the moment though before people come to have a look round.”
