Builder Michael Cotter made it through the crash in much better shape than most of his competitors. However, pre-tax profits at his Park Developments Group almost halved to 2.94m in 2015. At the end of 2015, Park had shareholder funds of 82m. Park Developments is currently building a 60,000sqft office building at Carrickmines in south Dublin. We are therefore increasing our estimate of his worth to 90m.
