The accommodation stands on the site of the Ritchies Mill, most recently known as the Mill Providore and Art Gallery.

SEVEN Rooms and Stillwater Restaurant co-owner Kim Seagram said the interior architecture, by Cumulus Architecture, took influence from the mill's fire of 1942. 

"We really wanted to pay tribute to that part of history, but we also wanted to show the new green shoot of where Tasmania's going to now," she said.

"Tasmania is being rediscovered and rising from the ashes of a troubled, dark, cut and burnt past is a nurturing, clever and creative place."

Everything in each unique room at SEVEN, from the furniture to the books, is Tasmanian.

As well as Cumulus, SEVEN was a product of local construction group Anstie and furniture pieces were specifically crafted by Simon Ancher and AH Beard.

"It's all totally bespoke to us," Ms Seagram said.

"The chairs are the only interlopers, they're Italian."

SEVEN will have mystery guests test the accommodation this week, pricing is expected to be between $350 and $550 per night.
