An 18th Century mansion destroyed by fire will undergo a £30m reconstruction, it has been revealed.

Design teams are invited to submit plans for Clandon Park house in Surrey - reduced to a charred shell in 2015.

Owner the National Trust said plans would combine restoring state rooms with new galleries and visitor spaces, in a building that "reads as one".

The fire, thought to have been started by an electrical fault, left one room - the Speakers' Parlour - intact.

Several hundred artefacts were recovered and many found in the debris await conservation.

Dame Helen Ghosh, the trust's director general, said the building was "a masterwork of its time" and needed sensitive, thoughtful restoration.

She said the trust wanted to attract the freshest thinking "to help us bring it back to life".

Project director Paul Cook said the Grade I-listed building had "an exceptional aura and history".

He said: "The trauma of the fire and sense of loss we feel heightens our determination to transform the visitor experience at Clandon and give the house a higher profile."

The trust said the high-profile project had a £30m construction value.

The house near Guildford captured a moment in architecture when Baroque made way for Palladianism in England, the trust said.

Designed by Venice-born architect Giacomo Leoni, it concealed celebrated interiors, including a glistening white Marble Hall, within red brick walls.

The public will be able to comment on proposed designs this summer and a competition "jury" will be chaired by Sandy Nairne, trust board member and former director of the National Portrait Gallery.
