The newly created role will see Shepherd chair the trade arm of the Glasgow-headquartered group, with a remit covering operations in timber systems, contracts, strategic land, and Scottish and English homes.
Shepherd joined Mactaggart & Mickel in 1990 and will celebrate 30 years with the firm in January. He has held several construction and project management roles during his career and was appointed a director in 2011 with responsibility for production and strategic planning.
He also sits on the management board of Hillcrest Homes, a provider of affordable homes in Scotland.
Shepherd said: “As chair, my key priority will be to work with my colleagues ensuring we continue delivering fantastic homes for our clients in a sustainable, consistent and productive manner across our growing geographic area and client base.”
Group chief executive Ed Monaghan added: “Peter’s experience and mix of skills have driven the successful expansion of our housebuilding arm over three decades. His new role gives him overall responsibility for ensuring that the Mactaggart & Mickel construction excellence continues outside Scotland.”
