After joining the family firm, Bell Brothers, Bell was made the director of the family's large factory, the steelworks at
Middlesbrough. He also served as mayor of Middlesbrough three times – in 1874, 1883 and 1911. He was, like his father, a director of the
North Eastern Railway, and had a private platform on the line between Middlesbrough and Redcar, at the bottom of the garden of his house, Red Barns. He was treated as royalty by the railway. His daughter, Lady Richmond, recalled saying goodbye to her father at King's Cross. He stayed with her on the platform to chat until the train left. When the train did not leave on time, they went on talking, until at last a guard came up to them and said "If you would like to finish your conversation, Sir Hugh, we will then be ready to depart." In 1885, Bell's father was created a
Baronet, a title he inherited in 1904. He was no ordinary capitalist and mill owner, but made sure his workers were well paid and cared for. ==Architectural commissions==
