One of the next batches of modular homes will be built close to the seafront in Dun Laoghaire.
It's also been confirmed the housing units will pop up at Whitebarn Road in Nutgrove, at Pinewood Green Court Balbriggan, and Wellview Green in Mulhuddart.
They'll be used to house homeless families until more permanent homes are built. The Tanaiste, Joan Burton, admits that's taking longer than she expected.
Meanwhile the Peter McVerry Trust is today opening 20 new Cold Weather Beds for homeless people in the city.
The charity's new family service will also move 44 adults and children out of hotel rooms in time for Christmas.
