The company announced today (9 October) that administrators Duff & Phelps have been appointed following a period of “difficult trading”.
Both sites appear to have closed, and their websites have been taken down.
“Trading at Artisan and Manchester House Bar and Restaurant has been much lower over the summer, and like many other restaurants, we have struggled with balancing rising costs and high rents, together with localised access difficulties,” says Jeremy Roberts, CEO of Living Ventures Group.
“I would like to take this opportunity to thank our brilliant and hardworking teams; we are currently contacting all affected employees and looking into available roles in other parts of the Group.”
Manchester House launched as a £3m project in 2013, headed up by chef Aiden Byrne. It was long-tipped to win a Michelin star, but never received the award.
Byrne stepped down from the restaurant to join D&D London last year, with his protégé Nathaniel Tofan promoted to head chef.
Living Ventures opened Artisan in a 12,000 sq ft space in Manchester's Spinningfields in 2013.
The group says its remaining sites continue to trade as normal.
It says anyone with reservations at Artisan and Manchester House will be contacted and offered alternative options at one of the other restaurants in the group.
Gift cards issued by Artisan or Manchester House will be redeemable at Australasia Restaurant until 31 March 2019.
