One of Canada's best known golf course architects, Furber's fifty years' experience in creating golf courses was laid on solid foundations. During the early part of his career, from 1969 until 1980, he honed his design skills while working with the legendary Robert Trent Jones Sr. During these 11 formative years, Furber worked on "RTJ" projects, including several in Europe, Morocco and the Dominican Republic.

Branching out on his own in 1980, Furber became the founder and president of Golf Design Services (GDS), based in Canmore, Alberta. GDS developed a varied Canadian and international portfolio, including new designs, redesigns, renovations and restorations. As well as many new designs in his native Canada, GDS also crafted the first modern–day course in the Czech Republic (Karlstejn), the first 18–hole course in Cuba (Varadero), as well as other layouts in the United States, Switzerland and Germany.
