"Selling off this part of our portfolio and reinvesting in fit-for-purpose spaces is a far better outcome for both customers and staff."
The conditional agreement was signed on Monday and is subject to the approval of Asset Plus shareholders at a meeting scheduled in early June. Subject to that approval, settlement will occur by end of June 2019 and council will continue to lease the building for two years.
Asset Plus chairman Bruce Cotterill said the property would be redeveloped at the end of the lease term.
"Once refurbished, we expect the expansive floor plates and extensive views will be attractive to a number of these tenants. The Augusta team will be pursuing these potential leads immediately."
