He has over 35 years of experience in the construction industry and has held managerial positions within market-leading international consultancies.
His drive for pursuing this career comes from his great-grandfather, W.G.R. Sprague, whose love of heritage buildings saw him design many theatres in London with unsupported balconies.

Outside of work, Michael enjoys walking, being outdoors on his motorcycle and is a keen golfer, having played for the county at junior level.

James Sprague - Project Manager
James has been in the construction industry for 10 years.
Starting out as an apprentice, he has worked his way up to a managing level.
This means he now handles his own projects, undertakes site surveys, and communicates with external bodies such as engineers, councils, case officers, and clients.
James is quick to learn and has a real passion for assessing the practicalities of software such as Revit and AutoCAD and finding the most efficient methods of working.
The knowledge that he has gained over the last 10 years has enabled him to work his way from a simplistic job to one of a complex size.
In his spare time, James enjoys a ‘good’ game of golf and playing video games.
