The Dublin City Sheriff has seized the Ballsbridge home of bankrupt developer Tom McFeely.
The National Asset Management Agency has taken over the mortgage.
The High Court ordered Mr McFeely, his wife and two teenage children to move out of their home on Ailesbury Road, Ballsbridge because of a default on a €9.5m mortgage.
It was taken out on the property during the boom when the house was valued at €15m.
But no repayments have been made in over three years.
The court had allowed extra time for the repossession to allow one of the McFeely's children to complete his Leaving Cert at the exclusive St Michael's College across the road.
Mr McFeely who successfully appealed a three-month prison sentence over safety standards at Priory Hall is challenging his declaration of bankruptcy.
