Tiger Developments’ plans for a hotel scheme in Haymarket in Edinburgh have been called in by the Scottish Government as Unesco arrives in the city to inspect its heritage credentials.
The call in came as Unesco inspectors visited Holyrood to investigate the capital's World Heritage status and view prominent development sites.
Tiger had signed up hotel chain Intercontinental for a five-star hotel at the heart of the £200m development and experts thought the scheme would not be called in.
Councillors backed Tiger’s project earlier this year, but the Scottish Government had to be asked to approve it because the council previously owned the site.
Ministers have said this week it has been called in to examine concerns that the scale of the building will damage the city's skyline.
The Unesco visit has been prompted by concerns over the city’s status.
The council passed a controversial Caltongate planning application which some have suggested could have a detrimental impact on the city’s old town.
Concerns have been raised over Mountgrange’s £300m Caltongate plans and also Henderson Global Investors’ redevelopment of the St James shopping centre.
Edinburgh was awarded its world heritage title in 1995.
