An Bord Pleanála must reconsider the height of two blocks of apartments being built by developer, Johnny Ronan in Dublin's docklands, after a High Court ruling today.

Dublin City Council had challenged the board's decision in December last year to allow one block to be increased from seven storeys to 13 and the second from seven to 11.

The Court overturned the decision, on consent from both sides and the matter must now go back to the Board for reconsideration. 

The Spencer Place Development Company wants to build more than 500 apartments, co-living spaces and commercial units in the North Lotts/Grand Canal strategic development zone of the north Dublin Docklands.

The company lost a High Court challenge last year to the city council's interpretation of 2018 building height guidelines issued by the Minister for Housing Planning and local government.

The city council argued that the planning scheme for the lands only permitted heights of up to 10 storeys.

The company appealed to An Bord Pleanála which overruled its own inspector's recommendation and gave to go ahead to increase the heights. 

The Council began a legal challenge but Mr Justice Denis McDonald was told today the parties had agreed he could make today's on consent. 

Senior Counsel, Paul Gallagher for the developer said the matter was urgent as it related to a construction site and a large number of employees.
