TBT Engineering Consulting Group, N.M. Paterson Building

This building shares the story of Norman Paterson, whose pursuits in the grain-trade industry brought him to Fort William in 1908. Paterson’s successes saw this property develop from a small building, wooden grain elevator, workhouse and dock into the headquarters of a vast grain-handling and steamship firm. Now home to TBT Engineering, restoration and preservation of this site continues.
