The Irish Housing Market has experienced unprecedented success over the last decade, with record levels of growth. The housing boom has seen prices spiral by up to 300%, with over a third of all housing stock being produced during this period. This book intends to follow Ireland s journey in its quest to explore the contributory factors that led to the housing boom and the future perspectives on the Irish Housing Market. The book establishes the driving forces for the housing boom, including the role of financial institutions and the construction sector. To present an unbiased and balanced approach to the main arguments of the paper, interviews were conducted with a sample of the major players within the Housing Market. Participants include a property developer, a banking representative and David Mc Williams (Economic Commentator).Data Analysis establishes common threads of the arguments and contrasting outlooks on the Housing Market. After fifteen years of a Housing Boom, Ireland is experiencing a housing downturn. The House Party is Over, and how Ireland intends to overcome the hangover is outlined in the final conclusions and recommendations of this research paper.
