Set up in 1970 by Tricia Guild (pictured) with a single showroom on London’s King’s Road, Designers Guild has put its vibrant stamp firmly on our interiors. Forty years later, you can buy its fabrics, wallpapers and bed linen in more than 60 countries. It sells Tricia’s own designs and top Brit names such as Jasper Conran, plus the Royal Collection on behalf of the Royal Household. This year, the company has launched a showroom in Marylebone, a new online store and digitally printed wallpaper and fabric ranges.
