Work has got underway on the interior fit out of the £30 million redevelopment of Aberdeen Art Gallery.Being spearheaded by Hoskins Architects, the project will see the A-listed civic space converted into an arts venue.It will include 21 new exhibition and display galleries as well as improved visitor facilities alongside transformation of Cowdray Hall into a performance space and refurbishment of the Memorial Hall as a place of quiet contemplation.To accommodate these functions a new wing will be built to the rear whilst a pitched roof and parapets on the main building will make way for a new sculptural copper-clad penthouse level hosting temporary galleries and a learning zone.
