Description

The Valve House stands on a high battered base of rock-faced stone, but is otherwise of quarried stone with rock-faced quoins, under a hipped slate roof on swept eaves that gives the building its distinct profile. The main access is a doorway in the E wall under a concrete lintel. In the north wall is a single-light window and in the W wall a mullioned 2-light window with concrete dressings. A (later) outshut, with corrugated asbestos-cement roof, is on the N side. It has a doorway at basement level on the W side facing the dam, below a 2-light wood-framed window, both under concrete lintels, and a further boarded-up doorway in the N wall and there are further stone and blockwork additions on the N and E sides of the outshut.
