A hotel developer behind controversial plans to convert an iconic former Edinburgh school has revealed scaled-back proposals.

Duddingston House Properties and Urbanist Group are behind plans to transform the A-listed Royal High into a luxury hotel.

The £75m hotel option has already been turned down by councillors, with rival plans to move St Mary's Music School to the building already gaining planning permission in principle.

The hotel developers revealed revised proposals for the neoclassical building on Thursday ahead of a public consultation on a fresh planning application bid.

The size of the new-build "inca wings" of the hotel has been dramatically reduced.

It is understood there will be fewer than 147 rooms in the revised proposals but further details have not been revealed.

David Orr, chairman of Urbanist Group, said: "Members of the public and interested groups will be able to see our revised design for restoring the Old Royal High School and reinvigorating the public space around this side of Calton Hill.

"Significant modifications have been made to the scale of our plan. We have made changes to the scale of the hotel following a series of design workshops earlier this year with planning officials, taking careful consideration of heritage aspects and public comment from our previous proposals."

Mr Orr said the "sensitive, fully-funded restoration of an architectural masterpiece" would help create a world-class attraction.

He added: "The building's architectural significance links back to the Scottish Enlightenment and the projection across the globe of Scottish thinking in science, philosophy, economy and the arts.

"The worldliness and ambition that underpinned that great age is an essence we want to draw upon in creating with Rosewood Hotels a space in which all that is truly excellent in Scottish food, culture and music can be celebrated with the rest of the world."

The firm says the development would create more than 250 jobs in the hotel.

Duddingston House Properties and Urbanist Group previously won a commercial bid with the council to develop on the site, which technically means they have until 2022 to submit any new planning application.

The planning approval for the music school also includes an extended seven-year timescale for planning and listed building consent, however.

The public consultation on the plans will be held at the Royal High on Thursday from 3pm to 7pm.
