Aberdeen City Council has lodged a petition with the Court of Session as part of the proposed redevelopment of Union Terrace Gardens.
The local authority confirmed it has launched the legal document as part of the process of using Common Good land for the proposed multi-million redevelopment.
The land in question relates to where new entrance buildings will be constructed at Union Terrace and opposite His Majesty’s Theatre.
Common Good land is essentially land held in trust, by the council, for the people.
It would continue to be in public ownership and the petition is separate to the ongoing planning process.
Designs for the site were drawn up and released by London Olympic Park outfit LDA Design and include new entrance buildings, cafes, a gallery area and events space.
The proposals aim to conserve the Victorian park’s heritage and to “sustain Aberdeen’s performance in times of economic difficulty”, according to a design statement.
This restoration will see the toilets completely restored to their former glory, including the retention of glazed wall tiles, cast iron fixings and stain glass windows.
An entrance building is set to be constructed on Union Terrace to provide space for a cafe and viewing gallery as well as flexible exhibition space.
The building will also offer a new gateway to the arches located below, which will be backlit to brighten the spaces and increase safety, particularly at night.
Plans to revitalise Union Terrace Gardens under the City Centre Masterplan were approved in principle in March 2017.
The detailed planning application for the project was submitted in April 2017 and is awaiting determination.
The Scottish Government states that by far the largest component of Common Good Funds is heritable property which mainly consists of public buildings and spaces such as parks.
