Work to convert one of Dublin city’s oldest buildings into a homeless hostel has been stopped following the intervention of the Department of Arts, Heritage and the Gaeltacht.

The Peter McVerry Trust had planned to use 21 Aungier Street, believed to date from 1667, to accommodate homeless adults.

The building is a protected structure and a registered historic monument, with any work requiring the consent of the Minister of Arts, Heritage and the Gaeltacht. The trust had not received this consent before starting work on the building.

Work to reconfigure the house started last month. The Dublin Civic Trust, which restored the building in the 1990s, when it had been derelict and under threat of demolition, had objected to the development which it said could compromise its historic fabric.

Peter McVerry Trust chief executive Pat Doyle confirmed officials from the department had visited the building on Monday.

Notice period The charity had not given the required two-month notice period to the department before beginning work, Mr Doyle said.

“We understand that we have obligations under the national monuments legislation, but I am very confident that we in no way damaged the building.”

Mr Doyle said he saw no reason that historic buildings could not be used for homeless accommodation. “If I could use the Áras, I would.”

Assistant Dublin city manager Brendan Kenny said the building would not be used as a homeless hostel.

“Peter McVerry Trust has withdrawn from the project and it is not going to progress. We will be looking now at other options for homeless accommodation throughout the city.”

The failure to seek ministerial consent had been a mistake, Mr Kenny said. “Projects are moving very fast . It was just an error not to give the two months’ notice.”

Independent councillor Mannix Flynn said the council had failed in its duty to protect the building. “This is a very damaging and unfortunate scenario for Dublin City Council and for the Peter McVerry Trust. Leaving aside the issue of homelessness, nobody is above the law.”

Aungier Street was laid out in 1661, more than 10 years before St Stephen’s Green, as a residential street for the elite. Chosen for its proximity to Dublin Castle, it gave rise to a new type of house, the “city mansion”.
