A number of residential block typologies were examined to achieve within a three to six storey limit, the density and mix required. Generators of the design proposal included the enclosure provided by the listed cut stone perimeter wall and defined entry points, the terraced site and listed Isolation Hospital with its strong cruciform plan. The Isolation Hospital enjoys a commanding position on the upper tier of the site. It will accommodate a Crèche, Restaurant and Community Resource Centre, providing an important interface with established residential communities of Infirmary Road and O’Devaney Gardens.
