Property developers Ardstone Homes has filed for planning permission with An Bord Pleanala (ABP) for the construction of 590 dwellings on a site on the Scholarstown Road in Knocklyon.

As per a description of the development, 480 of the units will be build-to-rent while 110 will be build-to-sell.

The development will range from three to six storeys in height with the build-to-rent units being a mix of one- and two-bedroom apartments while the build-to-sell units being a mix of two- and three-bedroom homes.

The site was previously the home to former Taoiseach Liam Cosgrave who passed away in October 2017.

After Cosgrave’s death, Ardstone purchased the land and applied for permission to demolish the cottage in which the former Taoiseach lived.

However, earlier this year the site was the subject of an archaeological excavation in which the partial remains of 83 people were found. It is believed the remains belong to a settlement which dates back to the early medieval period.

After South Dublin County Council gave granted the demolition of the cottage, local Fianna Fail TD, John Lahart filed an objection with ABP citing the “significant” archaeological discoveries on the grounds.

A public meeting discussing the proposed development took place this past Sunday in St Colmcille’s Community School.
