Charity group Focus Ireland plans to provide 800 additional units of accommodation as part a new strategy to help tackle homelessness.
Focus says 80 per cent of the housing will be for single adults - who represent the vast majority of homeless people - with 20 per cent for families.
Focus Ireland said its strategy had been drawn up in response to the continued problem of hundreds of people becoming homeless annually
The cost of the plan has been estimated at €200 million over five years, with most of the finance coming from the State and other statutory bodies.
Focus says it intends to raise €37 million of total itself through fundraising. The group also said it would double its tenancy support and settlement services - which provide support to help people move on to independent living in local authority or private rented accommodation.
A recent housing report by the National Economic and Social Council claimed that an increase of 73,000 housing units between 2005 and 2012 is needed to tackle the backlog on the waiting lists.
It also highlighted the fact that social housing output as a percentage of overall housing output fall to just 6.6 per cent in 2004 - only half what it was a decade ago.
Focus Ireland said its strategy had been drawn up in response to the continued problem of hundreds of people becoming homeless annually and the challenge of providing long term housing to move people out of homelessness.
But it insisted housing alone will never fully solve the problem of homelessness.
Speaking today Chief executive Declan Jones said: "Everyone of us knows that having a home is not just about the bricks and mortar. It is a feeling of belonging, of being in a place we share with family, a place in which we can let down our guard and be ourselves."
Mr Jones said: "Feeling at home is also being connected to the wider community through education, work and leisure. Many of the people we work with are not just without somewhere to live but are also disconnected from family or society."
