The former Wallace Craigie jute works, known locally as Halley’s Mill, on the city’s Broughty Ferry Road was razed to the ground after diggers moved on site on Friday May 11.

A building standards officer from the local authority was present as the remainder of the derelict building was brought down the following day.

“Our concern at this stage is that the building is left in a safe condition,” he said at the time.

However Dundee City Council has now confirmed that an investigation into the demolition of the B-listed building is underway.

A statement was issued confirming that officials were seeking urgent talks with the property’s owners.

A council spokesman said: “The council has been made aware of the situation. We are investigating and will discuss this with the owners as soon as possible.

“The process of gaining a demolition warrant under building standards is separate to that required under planning legislation to demolish a listed building.”

The local authority approved a building warrant for the demolition of the former jute works in April after it had sat derelict for decades.

Planning permission was previously granted to convert it into flats as part of a wider development. This would have seen Craigie Estates Ltd incorporate the facade and features into a modern block.

However, the development did not go ahead and the mill was condemned by council building standards officers.

The site owners applied for a building warrant to demolish the structure in its entirety in December last year.

Historic Environment Scotland has pledged to assist the council in its investigation.

A spokeswoman said: “We are aware the council plans to investigate the demolition of Craigie Works and have been in contact with the owner.

“It is highly unusual for the demolition of a listed building to take place without following due process and if this is the case here we will assist the council in any way we can.”
