A Dundee woman who sold her home at almost half of its value because of Raac said private homeowners must receive financial help to repair affected properties.

A £21.6m repair scheme for Dundee council properties affected by Raac (reinforced autoclaved aerated concrete) has been approved by councillors.

However, 237 privately-owned properties in the affected buildings will have to contribute to the cost of the repair work.

Yvette Hoskins, who sold her flat in a Raac-affected building for £55,000 despite its £100,000 value said the experience was "daunting and devastating".

The local authority said 783 properties within 171 cottages and 74 blocks of flats were affected.

Work on the scheme is expected to begin in January. It follows a £500,000 pilot project last year involving five unoccupied properties that were affected.

Yvette, who lived at a flat in the Craigie area of the city with her husband and two children, managed to sell the property after an initial sale fell through.

The family had been in the process of selling their flat when the material was found in the block's roof.

The property was on the market for more than a year.

"Our future home fell through, because we were unable to purchase it," she said. "The whole experience was extremely daunting, devastating, emotional, tearful.

"We could not believe that we had to sell our property at such a low price, it was super difficult."

Yvette said the flat eventually sold for just over half of its value.

"The lowest price we were offered was £35,000 on a property valued at £100,000," she said.

Yvette, who chairs the Dundee Raac Campaign Group, is calling for private homeowners to receive financial help for their share of the repairs.

She said: "A lot of homeowners still believe they were mis-sold their properties.

"They bought their properties in good faith with no knowledge of Raac."

She said they had also never been informed of Raac being present in the properties.

"They are very angry that nothing is being made available to them at a local authority level or a government level," she said.

"They have no support, they face a lifetime of debt, their homes are their lifelines."

At Monday's meeting, when the repair scheme was approved, Yvette asked councillors to consider alternative options.

This included full Raac removal from homes or a buy-back scheme allowing private owners to sell their properties to the council.

Council officers said a buy-back scheme would not be viable.

Dundee City Council leader Mark Flynn put forward an amendment during the meeting.

This asked the chief executive to write to Angela Rayner, the UK government's secretary of state for housing, and the Scottish government's housing secretary, Shirley-Anne Somerville, to seek financial support and a dedicated funding mechanism for owner-occupiers affected by Raac.

He also asked for assurances that work carried out to remediate Raac would be accepted by both mortgage providers and insurers.

The move was unanimously backed by councillors.

Raac, a cheaper alternative to standard concrete, was used mostly in flat roofing but also in floors and walls between the 1950s and 1990s.

However, it is less durable and susceptible to structural failure when exposed to moisture.

Dundee councillors were told the pilot repairs demonstrated that the preferred "fully supported" remediation approach was "technically viable" across a range of house types and could be delivered using conventional materials and construction methods.

The system uses plywood, timber joists and, where required, steel beams to provide support beneath the Raac so that it no longer performs a structural function.
