The development is directly adjacent to the Royal Hospital Kilmainham and, as part of the scheme, the Irish Museum of Modern Art (Imma) has been guaranteed 4,000sq m of space in what is termed the Heuston South Quarter. This site was earmarked for a new Imma gallery. As Imma's director Enrique Juncosa has pointed out, the museum needs a new, purpose-built gallery space to accommodate both its growing collection and the kind of exhibitions that it wants to feature in the future. The provision of such a space for temporary exhibitions would have the benefit of freeing up the galleries in the Royal Hospital building for showing a greater proportion of the permanent collection. It is generally recognised, for example, that there is no gallery in Dublin where residents and visitors can see a representative collection of Irish art from the mid-20th century onwards.
