Council chiefs have applied for listed building consent ahead of carrying out a multi-million-pound renovation of Provost Skene House.
Aberdeen City Council plans to reopen the building, originally built in 1545 and now located in the heart of the Marischal Square complex, as a “Hall of Heroes” celebrating the city’s finest sons and daughters.
The house was initially expected to reopen its doors to visitors at the end of 2017 but in February it was announced the attraction will now launch in the winter of 2019-20.
Councillors approved a range of conversation work for the 16th Century property on Guestrow later that month. This includes re-slating the roof, repairing rotten timbers and giving both the interior and exterior a new coat of paint.
Work to remove algae from its stones and replace cracked window panes will also be carried out.
The local authority has submitted an application for listed building consent to carry out the works.
Earlier this week, prior to the application being lodged, the council’s opposition SNP group criticised the council’s ruling Labour, Conservative and independent coalition for delays to the revamp and other major projects.
However, administration leaders said the nationalists were “talking the city down”, rather than acknowledging the “massive amount” of public spending the council is investing.
The council previously said preparations were under way to “conserve and improve the fabric of the building” in advance of its conversion and that new display materials were being sought.
Provost Skene’s House had previously housed a series of period rooms, furnished to show how people lived in the 17th, 18th and early 19th Centuries.
It closed to allow for the construction of the Marischal Square complex.
