Among the pieces feared lost in Monday's blaze were works by Damien Hirst, Tracey Emin and the Chapman brothers - leading members of the 1990s Brit Art movement known for often shocking creations.
Dinos Chapman said his tableau, titled ``Hell,'' was destroyed, The Daily Telegraph reported Wednesday. The work, which he produced with his brother, Jake, consists of thousands of model Nazi soldiers committing atrocities, and was sold to Saatchi for $900,000.
Other works from Saatchi's extensive private collection were destroyed at the warehouse owned by art handler and storer Momart.
``Charles is absolutely devastated,'' a representative for the collector said on condition of anonymity. ``Obviously works have been lost, but until we can confirm more, it's probably wrong to comment.''
Carole Hastings, director of Momart, refused to identify the artists whose work had been lost or give the value of the destroyed pieces.
Firefighters were at the warehouse Wednesday, but it would be hours before they could assess the damage, said fire brigade spokesman Nick Comery. TV pictures showed smoking rubble and twisted metal - all that remained of the storage facility.
Dinos Chapman shrugged off the loss of ``Hell,'' which took two years to complete.
``It has burnt,'' he was quoted as saying. ``We have had it confirmed by two or three sources.
``We will just make it again,'' he added. ``It is only art.''
Among other famous works feared lost in the flames was Emin's ``Everyone I Have Ever Slept With 1963-1995,'' a tent embroidered with the names of all her sleeping partners.
The fire was also thought to have claimed works by Hirst, famed for his works of pickled sheep, dismembered cattle and a shark in a glass tank. Momart stored some of Hirst's trademark spot paintings, his sales manager, Franky Dunphy, told The Times of London.
