CIE's bus garage at Conyngham Road in Dublin is one of a number of sites that will not be transferred to the Land Development Agency for housing until between 2027 and 2030.
Yesterday, ministers expressed frustration at the pace of progress of the transfer sites to the new agency.
According to the Government Information Service, the Cabinet yesterday requested all departments to identify further potential sites within the State's property portfolio that would be suitable for housing.
It added: "The purpose of this specific programme is to ensure that every effort is made to identify State land and properties which can be re-purposed to increase the supply of housing in the long term."
A spokesperson for the Department of Housing said: "Yesterday we had a call for the Government Departments to go again and look at what they have."
Sinn Féin's housing spokesperson Eoin Ó Broin today criticised the design of the LDA, which he said lacked the power of compulsory purchase orders.
He said this had been pointed out to the Government when it was introducing legislation setting up the agency.
Some ministers are understood to be perplexed at the lengthy delays given that the State already owns the lands.
The Government's Housing for All strategy identified 20 sites, including places such as old army barracks and disused schools, which should be transferred to the agency for new housing developments.
Departments have now been asked to find potential new sites within the State’s property portfolio that would be suitable for housing.
This would then be delivered by either the LDA or local authorities.
Last week, the Government gave the green light to the LDA to proceed with a plan for 597 homes at Shanganagh in Dublin.
This was the first project backed by the agency. It will include 306 cost rental homes, 200 social and 91 affordable homes.
