The Manchester United legend and current Ireland assistant manager bought the property when he managed the Tractor Boys between 2009 and 2011.
And with his current commitments to the Irish team, rumours have been spreading that the Mayfield man may be set for a return to his native city.
The Irish Examiner has learned that Keane has been discretely viewing a number of off-market properties on the northside of the city.
A very private family man, he and his wife Theresa, have five children, one already attending University College Cork, and extended family across the city.
Now Keane’s seven-bedroom, detached home in Woodbridge, Ipswich, is on the market for £3.5m. Set on over three acres, the property is described as having been “refurbished to an extremely high specification” by a local management company, The Cotton Tree.
The house comes with seven double bedrooms, four with en-suites and two family bath/shower rooms.
The property also has a tennis court, swimming pool, and tree house.
Creative director of the company, Jules O’Dowd, was tasked with designing the interior of the home and worked closely with the Irish legend.
Speaking to the East Anglian Daily Times, Ms O’Dowd said Keane’s fiery image was some way removed from the reality of the man in person.
“He was one of the most sincere, wonderful men. His wife, too. Just lovely people. I did his house when he moved to Woodbridge.
“People always say: ‘He must have been...’ and then they make a face, but I always say: ‘He was gorgeous’. Because he was. The loveliest man and so easy to work with,” she said.
Ms O’Dowd said she sometimes texts Keane when she sees him on TV and recalled “an interesting conversation” they had about management styles.
“He once asked what were my tips because he had so enjoyed working with my team. I told him, ‘A boss is only as good as the slowest person. They are a metronome to the business. If you know someone is taking the business backwards, move them on.’ It was funny to be discussing management with him, but managing people is the same really whatever area you work in and, essentially, we both work in a creative world,” she said.
