The Old Schoolhouse, 27 Croft Street, Penicuik

This is a late 19th century former service block, originally part of 25 Croft Street in Penicuik, now used as a private residence. It is a single storey building with an attic, arranged in a near H-plan with an asymmetrical design. The building is constructed of stugged ashlar sandstone, with a stugged, squared and snecked stone projection at the front entrance on the left side and a single storey, two-bay lean-to addition on the right side. The stone dressings are stugged with projecting cills, and the principal elevation features stop-chamfered arrises and stone mullions in the bipartite and tripartite windows.

The northwest (entrance) elevation has a single storey entrance projection on the far left, containing a modern six-panel timber door with a radial semicircular fanlight. The central three bays have regular fenestration. A modern glazed timber door and a window are located in the two-bay lean-to addition on the right, and a single window sits in the remaining bay at the far right, with a small light in the re-entrant angle.

The northeast gable has a window to the right of centre and a window on the far right, both at ground level.

The southeast (principal) elevation features a pair of tripartite windows flanking the centre at ground level. An advanced gable to the right is surmounted by a decorative gablehead bellcote, and French windows are centred at ground level beneath a two-pane rectangular fanlight, all enclosed by a modern conservatory built on a brick base. An advanced gable to the left is surmounted by a stone finial, with a bipartite window to the left of centre and a single window to the right of centre, both at ground level. A window is centred in the attic. A timber panelled door is located in the re-entrant angle to the right.

The southwest gable has a window to the left of centre at attic level.

The interior was not inspected in 1999.

The building has a variety of timber sash and case windows. The roof is covered with graded grey slate, with a lead ridge that slopes down to the rear of the entrance projection; a tarred asphalt roof covers the lean-to addition. There are modern skylights on the entrance elevation. Two regularly-spaced, louvered, slate-hung dormerhead ventilators are present on the principal elevation, and three are on the entrance elevation. Cast-iron rainwater goods are used throughout. The building has gablehead and shouldered wallhead stacks with coped details and circular cans. Sawtooth coped skews are also present, with some gablet skewputts.
