Sinn Féin's housing spokesperson has said there is a growing consensus that the market cannot deliver homes that middle-income can afford to rent or buy.
Speaking on RTÉ's Today with Sean O'Rourke, Eoin Ó Broin said he spoke with businessman Dermot Desmond about Irish housing policy after Mr Desmond wrote an opinion article on the topic in the Irish Times at the weekend.
Mr Ó Broin said he emailed Mr Desmond on Sunday about the article and the pair discussed it in detail yesterday.
The Sinn Féin TD said "architects, city planners, local authority chiefs and even some industry players" recognise that "there is a very large section of people for whom renting and buying is becoming increasingly difficult and who aren't eligible for social housing".
He said the market is building a large number of "high-end apartments" that are laying empty because they are too expensive.
Meanwhile, he claimed, local authorities are being prevented from building good quality, affordable homes that middle-income can rent or buy.
He said it was interesting that Mr Desmond calls for a "greater level of State intervention to use public lands, masterplanned by local authorities, and financed by the State, to deliver affordable homes for working people to rent or buy".
Mr Ó Broin said the scheme being developed by Dublin City Council at the St Michael's estate in Inchicore is an example which could provide 500 apartments, 70% of which would be affordable rental and 30% would be social rental.
"It's not just about delivering more homes but the right kind of homes in the right locations," he said.
He also called on political parties to inject urgency into government formation talks in order to begin addressing housing issues.
Meanwhile, South Dublin County Council has said it is to progress an affordable housing development in Killinarden, Tallaght that could provide up to 500 new social, affordable and private homes.
In a statement, the local authority said the proposed mix for the Killinarden site is for 300 affordable homes with 100 private and 100 social homes provided.
The local authority added that the development will include a new community centre and "sports pavilion".
