A major refurbishment occurred in 1988 and the upper storeys in Verco Building are now leased to the South Australian Government. A large underground car park was built where the basement was in the Myer Redevelopment and was engineered by Adelaide firm Ginos Construction. The car park is leased to Myer Centre Management, and so is some of the office space inside. It was listed on the South Australian Heritage Register on 11 September 1986.
