This document discusses the emergence and evolution of planning in Ireland from the late 19th century to the present. It outlines how an unregulated development frenzy in the 1990s and 2000s led to overbuilding, sprawl, and infrastructure deficits. The global financial crisis exposed flaws in how planning was implemented. It argues for a new approach centered on consolidating development, revising national strategies, and encouraging partnerships between the public and private sectors to plan for the common good. The planning profession is urged to respond through education, practice focused on sustainability and the public interest, and working within a plan-led system.
