An Bord Pleanala has approved plans for more than 8,400 homes to be built in South Dublin in a move that has left councillors "disappointed" and "insulted".
Plans for the new South Dublin town - with a population that would exceed 21,000 - will be based on 280 hectares of land at Clonburris, east of Adamstown.
The new development is part of a Strategic Development Zone (SDZ), which is said to help tackle the capital's housing crisis.

The approval of this zone means that South Dublin County Council can grant permission for developments which can't be appealed to the board.
As well as this, construction can start two months after the application is made.
ABP had made some changes to the local authority's plan - reversing proposals on height restrictions and and omitting others that would have tied the development of homes to the provision of public transport.
Councillors had proposed that Kishoge train station - built between Adamstown and Clondalkin in 2008 but never opened - must be operational by next year, and if that didn't happen, no further housing developments would be granted until it was opened.
However, ABP said that the provision would restrict the "timely delivery of residential development" and rejected it.
Councillors say they spent "many hours" debating and making amendments to the plan in 2018 and have been left feeling overlooked by ABP's decision.
They had put provisions in the SDZ which meant that new developments that were beside existing two-storey houses could only be a maximum of three storeys in height, but this provision was rejected.
Cllr Madeleine Johansson said: "Councillors made significant changes to the plan on issues such as building heights, public transport and exiting communities.
“It’s really disappointing to see the decision of the Board (ABP) to remove many of the good amendments councillors made to the plan such as public transport provision."
She added: "We worked closely with existing communities to achieve a plan that was sustainable and addressed the inadequate provision of public transport in the area.
“The removal of all of these in the plan is an insult to the work that councillors and residents have done.
"Instead we have an un-elected body make decisions which will have a massive negative impact on the local community, acting in the interest of the developers and land speculators.
"We need more housing, but we need it to be built in sustainable communities with adequate infrastructure.”
Councillor Francis Timmons added that although he approved the news of the housing, he was very concerned about transport, traffic and community services.
He told Dublin Live: "I voted for the SDZ not because I believe it was the best plan but because we are in a dreadful housing crisis.
He said: "We are now in the hands and at the mercy of the National Transport Authority, Government agencies, South Dublin County Council and Government departments to provide what is needed to deliver a sustainable community."
