79 new social housing homes have been launched on Charlemont Street.
It follows a long-promised regeneration of the area which was shelved when the economy tanked.

34 families who had been living in the flats will move into their new homes in November.
The complex will also feature a sports hall, community centre and play area for children.
Deputy city chief Brendan Kenny has paid tribute to locals in the area; "We very much appreciate the patience, resilience and support of the local community during this whole development."
Minister for Housing Eoghan Murphy says the government's determined to build more homes like these:
"We have ring-fenced over €5bn between 2016 and 2021 to increase the total number of social houses in the State by a third over that 5-year period."
