During his time at Marshalls the Duke of Gloucester was given presentations on the company's 105-year history, from the first quarrying of stone from the surrounding Pennine hills to its involvement on projects throughout the UK.
The Duke of Gloucester opened a new garden area at the office during his visit.
Marshalls chief executive Graham Holden said: "Marshalls was honoured to receive a visit by His Royal Highness the Duke of Gloucester. Being a qualified architect, he was extremely interested in the company's history and the projects we undertake in the UK and around the world today.
"He was also particularly interested to hear about our work in sustainability from the Carbon Labelling of our manufactured product range."
In 2008 Marshalls announced it had Carbon Labelled all its manufactured domestic product range.
