This unusual modernist church building reflects the transformation in Irish church architecture following liturgical changes and recommendations of the second Vatican Council. The church is a protected structure together with the priests’ house and parochial house which form part of the original ensemble. New additions were required to enhance the ongoing use of the church and parochial house, and to facilitate some increased and more diversified functions. In conforming with best conservation practice, the new additions adopt a respectful attitude to the original composition while the use of traditional detailing allows these to remain distinct and discernible as later work. The solution enhanced the functionality of the buildings while preserving the authenticity and integrity of the original design.
