The estate wants to convert an unused stable block to create a new entrance and to open a restaurant with a gift shop, office space, an upgraded ticket office and additional visitor attractions.

A Pictish-themed adventure playground is also proposed for the palace gardens, while new parking facilities could be created to the north of the site.

These would connect the palace to the Cross Tay Link Road, which will run past the palace grounds when it opens next year.

The estate says: “This will have a positive impact on traffic flow to the site, in addition to future events held across the estate.”

Under the change of use application submitted by Stormont Trading LP, the B-listed building becomes the new entry point to Scone Palace and Gardens.

The project could also feature a “solar meadow”, cycle storage, EV charging points, air-source heat pumps and a wastewater system that uses reed and willow beds.

Viscount Stormont, whose family have been custodians of Scone Palace for 400 years, said: “It represents a major opportunity to evolve and enhance the visitor attraction at Scone Palace, creating a positive step-change in our offering.

“The proposals will provide jobs locally, and it will enable renewed and lasting engagement with the local community.”
