MGS Architects will combine with a fellow Melbourne company, project manager Accuraco, to bring “the grand old building back to life”, Victorian Environment Minister Ryan Smith announced yesterday.

MGS has worked on the Crown foodcourt, the redevelopment of Bendigo library and masterplans for Monash and Victoria universities.

Accuraco has been involved in managing works at Melbourne Zoo and the Shrine of Remembrance.

The member for Benalla, Bill Sykes, backed the involvement of two “well-credentialled companies”.

Dr Sykes said he expected well-priced expert North East subcontractors to win work on the mountain.

He also expected the bulk of work to begin in spring with the project not expected to be completed for up to two years.

Approval has been given to demolishing basic accommodation, a staff recreation hall and a woodshed, while the facade, ballroom, dining room, main lounge and billiard room will be restored.

Dr Sykes said restumping work and asbestos removal had been occurring at the chalet over recent months as part of preparatory works.

The chalet has been closed since 2007 with an auction of its goods held early last month.
