Architecture and continuing use
The approximately twenty-five-bay range combines repeated arched windows with restrained Classical Modern detail. Its scale reflects the turbines and generators supplied by water delivered through the Ben Nevis pressure system.
Its story
The Lochaber scheme was created to power aluminium production. Original generating equipment and the relationship between tunnel, pipes, powerhouse and smelter give the site exceptional industrial coherence.
Why it is included
It links Highland water resources, twentieth-century engineering and continuing industrial employment in one nationally significant complex.
What to notice
- Long rhythm of arched powerhouse windows.
- Relationship to the descending pressure pipes and smelter.
- Restrained architectural treatment of a very large industrial building.
Reading the surroundings
This is an operating industrial and energy site. View only from lawful public places and do not enter controlled land, approach pipes or obstruct operations.
