In January 2006, Gibb purchased the former home of country singers Johnny Cash and June Carter Cash (the House of Cash) in Hendersonville, Tennessee, intending to restore it and turn it into a songwriting retreat. The house was destroyed by fire on 10 April 2007 while under renovation. On 10 July 2009, Gibb was made a Freeman of the Borough of Douglas (Isle of Man). The award was also bestowed upon his brother Robin and posthumously upon his brother Maurice. Also in 2009, Gibb and his wife became U.S. citizens, while retaining dual UK citizenship. Gibb has homes in Miami, Florida, and Beaconsfield, Buckinghamshire.
