The Dundrum Central Mental Hospital (CMH) is a landmark site with potential for significant residential development and reuse of key historic structures to develop a compact and integrated sustainable community for Dundrum.


Dundrum itself has a rich heritage and vibrant community which continues to evolve and grow. In recent decades, Dundrum has seen major infrastructural improvements including the Luas, a new road network and significant commercial and retail development.

The CMH site represents a unique opportunity to unlock this strategically located site to create a distinctive compact and integrated community as a new quarter for Dundrum.

The CMH is currently in use as an operational mental health facility. Following the completion of a new purpose-built facility in Portrane in the autumn, which will enable patients and staff to transfer, the CMH site will become available to progress plans to create an entirely new neighbourhood.

The lands provide a unique opportunity to transform this inward-looking site into a new, welcoming, sustainable urban community with a distinctive identity which will be integrated into the wider community of Dundrum.

The optimum residential unit mix and number and ancillary uses will be determined as part of the detailed design process, cognisant of planning policy requirements. It is envisaged that this compact development could include in excess of 1,200 new residential units with supporting community amenities. The development is also expected to include sensitive adaptive reuse of key heritage buildings within a distinctive landscape setting.


The site extends to
approximately 11.3 ha and
includes several existing
buildings on-site including the
Central Mental Hospital itself
which dates from c. 1850 as well as
mature trees and gardens


The location is accessible, being
just 800m from Dundrum
Village, and is close to public
transport, with Windy Arbour
Luas Stop (Green Line) 500m to
the west.


The site is currently fully enclosed,
surrounded by mostly 5-metre-high walls
which disconnect the land from the
surrounding communities and open space.
This project will look to integrate with
the surrounding community.
