In 2007 Halliday relocated to Dublin and began work for Hennessy Doyle Architects developing knowledge on high-end residential projects.     

In 2009 Halliday Ryan joined Jamie Falla Architecture (JFA) in Guernsey, Channel Islands. JFA is an award-winning practice and has received widespread international accolades with a number of published works.

In 2014, following five years in the Guernsey studio, Halliday returned to New Zealand opening up his own practice Arc Atelier Ltd.
