His promotion follows the retirement of Carl Read, who worked at Tilbury Douglas for almost 40 years, having started his career as a general building operative in 1983.
Since starting at Tilbury Douglas in 2006, Edmonds has progressed through a variety of senior roles, most recently as regional operations director for South Wales.
He also spent five years leading the £130m refurbishment of Prince Charles Hospital in Merthyr Tydfil.
Simon Butler, managing director for Building Central at Tilbury Douglas, said: “With extensive experience of the business and region, it is great to see Chris promoted to the role of regional director.
“We wish Carl all the best for his retirement and thank him for all his years of commitment to the business.”
