U2 band members Adam Clayton and Larry Mullen Jnr are among investors who have taken a legal action over alleged defects at a luxury apartment complex in south Dublin.
Residents of The Cubes complex have also hit out at alleged defects in their homes that could cost millions to fix. They claim they are facing problems including mould and damp.
People living in the Beacon South Quarter, in Sandyford, told the Herald how serious issues developed in recent years.
It comes as it emerged 200 investors have launched a High Court action over alleged defects at the apartments.
U2's Adam Clayton and Larry Mullen Jnr are among the investors to have begun the action, it has been reported. A total of 15 defendants have been named, including Laing O'Rourke Ireland, PJ Hegarty & Sons and John Paul Construction.
One woman said she had been living in the apartment for around eight years, but the problems only set in recently.
"I have problems with the bathroom with damp and now there's mould growing. There's also problems around the windows and with the ventilation," said the woman, who didn't wish to be named. "I know that a number of other residents have had it looked at, but I don't know what's happening," she said.
Another woman said she lives with her children in the apartment and she was concerned with the conditions.
"There is a problem with the ventilation, there's very noticeable marking on the walls and the air feels damp, which I'm concerned about with the kids.
"There's also a problem with the light, the way the apartment was built, we get almost no natural sun light," she said.
"These were supposed to be built to the highest standard, I can't believe we are having these problems," she added.
According to the woman, specialists had been sent to asses problems with the apartment.
"That was a while ago, but I don't know what's happened since," she said.
Some of the residents said they were tenants with Dun Laoghaire Rathdown County Council or the Circle Voluntary Housing Association, others owned the apartments or were renting.
The council was named as one of the prosecuting parties in the case against the developers.
Calls to the management company of the complex were not returned last night and the council could not be contacted. The Cubes are located in blocks as part of a large apartment complex, developed by Paddy Shovlin's Landmark Developments around 2007.
Many of the apartments were sold off the plans, with the most expensive fetching €1.1m. At the time they were hailed as luxury residences designed around a courtyard. In some cases, the apartments were built with two balconies. However, residents have complained that some of these balconies are now leaking.
There are more than 600 apartments in the development. Not all are affected by the problems.
