Apartment owners in a west Dublin development have raised concerns that their homes are not properly fire-proofed.

The apartments at Foxford Court in Lucan were built in 2004.

Many of the duplex apartments were sold by South Dublin County Council under the affordable housing scheme.

Last November, one resident discovered what he believed was a breach of fire safety regulations.

He found he could reach in under the wall into the apartment next door after he had lifted the floorboards in a bedroom.

A private contractor confirmed that cavity walls and floor penetrations were not installed properly to prevent the spread of fire and smoke.

It is understood that the council recently repossessed three properties in the complex and discovered that one of them did not comply with a Fire Safety Certificate and will require remedial work.

South Dublin County Council has written to another resident who raised fire safety concerns as far back as 2005 saying it is not liable for any remedial work and that the onus falls on the current owners.

The builders of the apartment block said they were unaware of the problems until media reports today.

Newlyn Developments said the Foxford Court scheme was completed and handed over to the council having complied with all regulatory and compliance issues and receiving appropriate certification.

The company said it had not received any communication about the matter and was not aware of the existence of any report regarding fire safety issues.

It said it was prepared to meet with all relevant stakeholders if asked to do so.

Calls from RTÉ News to Newlyn about Foxford Court went unanswered last week.
