Clandon Park, an 18th Century Grade I-listed stately home, in Surrey, was reduced to a charred shell during a blaze in April 2015.
Most of the interior will be conserved in its fire-damaged state, the trust said, with suspended walkways and platforms for visitors.
Restore Trust says the building should be returned to its original state.

The National Trust said it had moved on from a previous idea to restore some ground floor rooms.
The fire-ravaged rooms will instead be conserved and curated in their "laid-bare" condition, except one space that survived - the Speakers' Parlour.
The external walls and windows of the house are being restored, the National Trust said, with a new roof with public terraces and lights will provide views down into the house and across the countryside.

"People want to come and see the glory of the house, and you can only do that if you're restoring it to what it was originally."

"Given how little of the original decorative interiors survive, it would be less a case of restoration than of complete modern replication, and that wouldn't be the right approach to take."
He told BBC Radio Surrey: "[The fire] has revealed the remarkable and fascinating story about how wonderful houses like Clandon were built.
"We're planning to take the opportunity for Clandon to tell those stories."
He said the trust was aiming to have the house open to the public again in 2028.
