The Evening Telegraph has revealed that developers are poised to submit their proposals to transform Perth City Hall into an arts venue, which may see the historic Stone of Destiny as its main focal point.

Netherlands-based architectural firm Mecanoo is behind the approved designs and has already displayed graphics showing a gold- coloured entrance door on the north side of the B-listed building, along with another graphic depicting how the inside of the building may look.

The council will provide £20 million towards an upgrade of Perth city centre, including the transformation of the City Hall.

Engineers have removed the floor of the building and preparatory works are ongoing.

Residents will have the opportunity to view and comment on the multi-million-pound plans.

A council spokesman said: “We anticipate the full planning application will be submitted in the near future and will then be available for public viewing and comment on the council’s online planning portal.”
