Developers look to start a realignment and enlargement of the existing on-site ornamental pond for surface water attenuation.
They will demolish two existing shed structures on the site.
There will also be the installation of infrastructure along Cross Avenue to facilitate connections to the potable water supply at Cross Avenue and Booterstown Avenue.
Cairns Homes Properties originally submitted plans for the site in 2019.
Last year An Coimisún Pleanála refused permission for 355 build-to-rent apartments on the site,
Revised plans were submitted in August 2026, with permission granted in January of this year.
