Palumbo's development company was called City Acre, and he built their headquarters building in 1952, at 37A Walbrook, as the family office. Following an extensive conversion by Mark Birley, the Walbrook Club opened in 2000.
His portrait was painted by Oskar Kokoschka in 1960, and still hangs in its original position above the fireplace in what was his office, and is now the dining room at 37A Walbrook
Palumbo married Elsie Annie Gregory, a classical musician from Lancashire, and their only child was Peter Palumbo, Baron Palumbo, also a property developer.
Palumbo is buried in the churchyard of St Stephen Walbrook, London.
