Dublin City Council could sell off land worth over €100m to fund cultural, sporting and recreational projects.
According to The Irish Times, the council's chief executive, Owen Keegan, is in favour of selling the sites instead of using them for social housing.
Mr Keegan named 14 sites across the capital he wants to sell, which along with 15 council works depots would be valued at over €90m, and says more are likely to be added to the list.
Under the plan, five sites in Ballymun, Ballymount, Dolphin's Barn and Chapelizod would be sold by this summer -- raising an estimated €12.2m.
The rest would be sold in batches between then and the summer of 2022 - with Shelbourne FC home ground Tolka Park and the College of Music on Chatham Row among the most prominent.
Mr Keegan told the Irish Times most of the sites have been "idle for many years" and said housing wasn't "appropriate" for the sites.
City councilors have to vote to approve land sales and the controlling coalition on Dublin City Council has agreed not to sell land unless there is proof the cash return is worth more than the potential social and economic benefit of building new homes.
The list of 14 sites will be presented to councillors at their first full meeting of 2020, on Monday evening.
