Who We Are?



L.J. Millar Building Contracting was founded in 1976 by the late Leslie Joseph Millar. Leslie was brought up in a hard working family farm, but after leaving school he took a keen interest in Joinery  and Construction. Soon after Leslie had served his time he started contracting, setting a high standard  of quality workmanship, taking on work in both the Public and Private Sectors, and building good relationships everywhere  he went. In 1999 Leslie renamed the Business L.J. Millar & Sons with the coming on board of his sons Jonathan and Stephen. In today's market we offer a complete building contracting service and along side this we have a bespoke Joinery workshop. Today we pride ourselves on keeping the high quality service and relationships going just as our father had set for years.


Our promise as a contractor is to build community value into every project while delivering professional expertise, exceptional customers service and quality construction.
