Development of a primarily residential mixed-use scheme comprising 490 No. residential units (c.75,000 sq m) over a two/part three level basement (c.52,000 sq m) with ground floor level restaurants / cafes/ bars, retail and non-retail service units (c.5,500 sq m), a crèche/ healthcare facility (c.1,670 sq m) and a 151 No. bedroom hotel (c.5,600 sq m) designed by O’Mahony Pike Architects.
The scheme ranges in height from 9- to 12-storeys and integrates into the existing urban fabric by means of new pedestrian streets and public plazas, along with a new high-quality residential development.

Our Role

Tom Phillips + Associates (TPA) provided strategic planning advice to the Applicant and Design Team, and served as the Agent for the Planning Application. The project involved the management and coordination of a large multi-disciplinary design team including the preparation of an Environmental Impact Statement (EIS), Retail Impact Statement (RIS) and included careful engagement with the Planning Authority, Third Parties, Statutory Bodies and An Bord Pleanála.
Billed as ‘Project Trinity’ - given its location on what was once home to Trinity College’s Botanic Gardens - the site was brought to the market by Savills and Eastdil Secured in early 2015.
TPA were retained as Planning Consultants to provide planning advice on the development potential of the Project Trinity Lands, specifically in relation to the permitted scheme, potential variables and development schematics.
A summary of the key advice provided was incorporated into a video made by TPA that outlined the development potential of the property to potential purchasers.
The video is available to view on the property website -
