The judges said of Cook: "This is a journalist who makes you want to read on. Well-researched and clear, he puts forward a balanced case."
Cook – winner of the journalist of the year award in 1998 – was also runner-up to Baldock in the building category.
Regular Building freelance writer Elaine Knutt won the property section and came third in the building category.
Building's technical editor Andy Pearson was runner-up in the environmental category. Architectural editor Martin Spring was third in the housing award.
