It has now lodged an appeal against the proposals, which specifically rule out an Ikea-sized development.
The global giant had lobbied strenuously to be able to locate a store in Cherrywood, telling the council it wanted to expand due to the success of its Ballymun outlet.
A new store would provide a "significant quantum of jobs" in both the construction and operational stage, it argued.
But the strategic development zone (SDZ) document eventually agreed by Dun Laoghaire councillors prohibits retail warehousing.
When contacted today, Ikea said it is "committed to expanding in the Irish market and have been identifying sites in Dublin for a potential second store".
A spokesman added: "We have made representations to local authorities, in line with planning policies, to enable the possibility of a future store to the south of Dublin city. However, we have no plans to confirm at the current time."
Dun Laoghaire council told the Herald it is not in a position to comment.
The SDZ, a designation reserved for projects of national importance, makes provision for up to 8,300 new homes on 264 hectares of land in Cherrywoood.
The development of three new villages and a new town centre are permitted under the planning scheme.
Given the country's economic woes, the development is forecast to take many years to complete but, in the meantime, some sections of it will go ahead.
Six schools and 4,500sq metres of community centres are also to be built.
Councillors voted late last year to approve the massive land bank in south Co Dublin.
Among the other organisations that have lodged an appeal with An Bord Pleanala are NAMA, construction company Tudor Homes Ltd and the Cabinteely & District Residents Association.
A town centre as well as the three villages of Priorsland, Lehaunstown and Tully will eventually be built.
The land in question is primarily green field at the end of the Green Luas line between the N11 and M50.
Ownership is divided among a range of developers as well as the county council.
Dunloe Ewart -- formerly controlled by construction boss Liam Carroll -- is among the companies involved.
In a previous submission, Ikea outlined its belief that an outlet in Cherrywood would "stimulate wider economic impacts in associated builders and suppliers".
