Cosgrave Developments was founded in 1979 by brothers Joseph, Peter and Michael Cosgrave. Under their leadership, the Group has completed more than 5,000 residential units and 1.5 million square feet of commercial space and have accumulated an extensive investment portfolio, comprising offices, retail, leisure and residential units, both here in Ireland and the UK. The diversity of their portfolio, highlights their depth of knowledge, from developing Dublin’s iconic office building (No. 1 George’s Quay Plaza), to the complete restoration of St. Helen’s House in south Dublin, now a 5 star hotel managed by Radisson. The Group continues to be the market leaders in delivering energy efficient developments, having recently won numerous energy awards in 2014 & 2015, for their recent developments at Honeypark in Dun Laoghaire and Bracken Park in Castleknock. There is nothing as reassuring in Irish property, as the phrase “Cosgrave Built”.
