One of Gandon's finest designs
Abbeville house is considered one of the finest examples of leading architect James Gandon, whose better known works include the Four Courts and the Custom House.
The family took up residence at Abbeville in June 1969 just a week after Charles Haughey became Finance Minister, aged 44.
The politician paid €120,000 for the house and grounds. It proved an insightful investment and some years later, he recouped the entire purchase price, and more, by merely selling a field on the estate.
Estate agent Savills says the €7.5m asking price reflects a fair value in the current market.
"After all, two houses on Ailesbury and Shrewsbury Road, Ballsbridge, have sold for more than this amount in the last nine months and they were on small sites," said Savills Pat O'Hagan.
The same agent recently sold more than 400 acres of farmland in Co Cork for around €7m. While that may have been more land, Abbeville is in a prime location being close to both Dublin city centre and the suburb of Malahide.
