Locals and councillors are worried that a 5,000 year old neolitic tomb portal in Cabinteely will be "ruined" by plans for over 500 build-to-rent apartments.
The scheme by Cairn Homes Properties Ltd is across eight blocks with one block up to 10 storeys in height on a site at Winterbrook and Barrington Tower on Brennanstown Road in Cabinteely Dublin 18.
The scheme is made up of 30 studios, 135 one-bed units, 318 two-bed units and 51 three-bed units. It has been described being of a "very high quality design" and with "ready access to amenities" such as resident lounges, entertainment space and public transport.
