John Knott, of the Rochester and Chatham Dickens Fellowship, said the author wrote his books in the top room of the chalet
A £100,000 appeal has been launched to save the wooden chalet in Kent in which Charles Dickens wrote Great Expectations and other famous works.
The Rochester and Chatham Dickens Fellowship and Medway Council are jointly seeking to save the chalet, which has fallen into disrepair.
It once stood in the grounds of Gads Hill Place, Higham where Dickens lived.
It was dismantled in 1864 and rebuilt in the council gardens of Eastgate House, Rochester.
The building has already been restored twice, but plans are in place to re-use it in time for the 200th anniversary of Dicken's birth in 2012.
Councillor Howard Doe said the chalet would be relocated to the other side of the gardens and cultural events held around it.
