Valleyfield Mill School, Valleyfield Road, Penicuik

Valleyfield Mill School, located on Valleyfield Road in Penicuik, was designed by J A Bell in 1823. This picturesque group consists of two single-storey rectangular-plan gabled blocks set at right angles and connected by a gabled porch. The building features Tudor gothic detailing, including a gothic bellcote, and is constructed from coursed stugged ashlar with polished dressings. The windows are predominantly square-headed with hoodmoulds, and the edges are chamfered.

On the principal elevation, the advanced gable to the left is accentuated by stepped buttresses angled to both sides. At the center, there is a three-stage stepped bellcote that projects outward, featuring decorative two-light curvilinear pointed arch windows with hoodmoulds at the ground level, a decorative former clock face at the middle stage, and a cusped lancet arch opening topped with a cross finial at the apex. To the right, there is a gabletted entrance porch at the re-entrant angle, which includes a pointed arch doorpiece and a vertically-boarded timber door, with a buttress angled to the outer right. The right side has a three-bay arrangement that includes a centrally located two-leaf, four-panel timber door with glazed upper panels and a rectangular fanlight, flanked by a pair of multi-pane bipartite windows. There is also a low, recessed two-bay later wing to the outer right with a piended roof.

The west elevation features a four-bay layout with regular fenestration. The north elevation has a window centered in the gable to the right, alongside a canted single-storey modern rendered addition to the left with modern casement windows. The east elevation shows a blank gable, partly obscured by the canted end of the later wing on the left and a flat-roof rendered addition on the right.

Inside, there is a fireplace from 1860 in the style of Pilkington, which has a panel that reads, "Little Children Love One Another." The building has a variety of windows and is topped with graded grey slate roofs featuring lead ridges and modern prominent skylights. Decorative ashlar gablehead stacks are corniced with circular stone cans, and the skews are coped.

Additionally, there is a low, coped ashlar wall surrounding the property, which includes an iron gate and wall-mounted cast-iron railings adorned with decorative finials.
