Sron Mor Power Station, Sloy Awe Hydro Electric Scheme

Sron Mor Power Station, part of the Sloy Awe Hydro Electric Scheme, was designed by architect James Shearer for the North of Scotland Hydro Electric Board in 1955. This tall, single-storey power station has a rectangular plan and is constructed with rubble-faced Modernist design. It features lower blocks at the northwest and southwest corners and an oversailing tailrace to the southeast. The building is prominently located in upper Glen Shira, situated between the upper and lower Shira Dams. The exterior is made of random rubble with a banded concrete eaves course and concrete surrounds.

The northwest elevation, which serves as the entrance, has a roughly three-bay layout with advanced lower blocks at the corners. It features prominent recessed canted windows in the single bay returns to the centre. A tall, panelled teak vehicular access doorway is centrally located, framed in plain concrete, and topped with a rectangular geometric glazed fanlight that has a shallow triangular pediment above. The fanlight also displays the North of Scotland Hydro Electric Board coat of arms. Flanking the doorway are paired rectangular windows in the lower single-storey blocks.

The northeast elevation consists of roughly five bays, with an advanced single-storey section on the right (northwest). It includes three large rectangular windows for the turbine hall on the left (southeast), which have louvered vents above, all set in plain concrete surrounds. There is a window with an arched lintel off-centre to the right and a slightly recessed canted corner clasping window to the left (southeast) of the single-storey block.

The southeast elevation has a roughly three-bay configuration with a single large rectangular window in the centre. The southwest elevation mirrors the northeast, featuring the turbine hall (to the southeast) that oversails the tailrace on concrete piers and lintels.

Most of the windows have small pane metal glazing, with some featuring hopper openings, all set in painted metal frames. The building has a shallow pitched platform roof, and the metal rainwater goods are recessed behind the parapet.

Inside, the power station has a predominantly plain and functional interior, which includes an entrance vestibule and offices leading to a large turbine hall. A large travelling gantry crane is positioned on a steel gantry supported by substantial concrete piers.
