Residents living in a block of council flats were evacuated earlier this year due to unsafe concrete.

Cherwell District Council discovered reinforced autoclaved aerated concrete (RAAC) in the roof of Town Centre House in Banbury.

Work to make the building on the corner of Southam Road and Warwick Road safe is due to begin this autumn.

The council has since confirmed that Town Centre House is the only building it has identified as containing RAAC.

The extent of the RAAC crisis was first brought to light last week over safety fears at UK schools.

RAAC is a form of lightweight building material that was used in construction between the 1950s and 1990s.

It was mostly used in flat roofing but has also been found in the floors and walls of buildings.

RAAC was popular as a cheaper alternative to standard concrete, but it is considerably less durable, with a lifespan of around three decades.  

Town Centre House was constructed in the 1980s as an office block.

It remained empty for 10 years before being bought by Cherwell District Council for use as affordable housing in 2016.

A spokesperson for Cherwell District Council said that when the “risks became known” they took an “immediate decision” to relocate tenants.

The council added that the health and safety of residents is of “paramount importance” and that they have been on hand to provide support.

On Wednesday (September 13) Oxford City Council admitted that there may be unsafe concrete in some of its housing blocks.

The council said it was carrying out inspections as a “matter of urgency.”

A spokesperson told the Oxford Mail that some of its post-war public buildings may be affected.

They continued: “We will carry these out over the next three months.

“If we find RAAC we will undertake a condition survey and take appropriate action to manage any risks."

Both South Oxfordshire District Council and West Oxfordshire District Council have said that they have not identified any of their buildings as containing RAAC.

On September 6, Oxfordshire County Council confirmed that none of the schools it runs are affected by the concrete crisis.

A county council spokesman said: “Only one Oxfordshire secondary school is a local authority-maintained school, and around half of primary schools in the county are now academies.

“These schools are therefore run independently of the council and managed by the Regional Schools Director or Department for Education.

“The county council has been kept informed by a small number of academies in the county who do have RAAC issues but who have each come up with arrangements to ensure that children continue to be educated.

“Parents were fully informed of the individual situations at these schools by academy trusts earlier this week. The county council will help each school where it can.”
