A block of apartments owned by the National Asset Management Agency just outside Longford town have been demolished.
Residents in the Gleann Riada development on the Strokestown Road had claimed that the three-storey apartment block was in a dangerous condition and presented a safety threat to locals.
The apartments have never been inhabited.
Demolition was due to commence three weeks ago, but it was delayed because of the presence of birds in the building.
Officials of the Parks and Wildlife Service gave the go-ahead earlier this week for demolition to begin after the last of the nests were removed.
Meanwhile, residents in the same estate as the demolished apartments have said their houses are unfit to live in because of dangerous levels of carbon monoxide.
One home-owner at the Gleann Riada development has already been evacuated because of high readings of gas in the estate and others living there have appealed to NAMA and Longford County Council to take urgent steps to make their homes safe.
