Description

The Valve-House, part of the Kinlochleven Hydroelectric Scheme and former aluminium smelter, was designed by architect H Scott Alban and supervised by General Manager W M Morrison between 1905 and 1909. This single-storey building features a pitched roof and is constructed with granite rubble facings and a reinforced concrete frame. It has four bays and is a key component of a large high-head hydro-electric scheme that provided electricity to the nearby aluminium smelter, which was demolished in 2002.

The south elevation has bi-partite windows in the center, flanked by single rectangular windows in the outer bays, all set within raised banded margins. The gable ends are blank. Adjacent to the south and east elevations, there is a fixed spillway and a catchment pool. The roof is made of pitched corrugated aluminium and includes a single coped stack on the left (west) side with a clay can.
