Greig Institute, Forth Street, Leven

The Greig Institute, built in 1872-4 by Andrew Heiton (Perth), is a two-storey, three-bay building designed in the Domestic Gothic style, with a later single-storey, cottage-style extension. The walls are harled with contrasting, roughly-shaped ashlar stone dressings. A raised base and ground floor cill, along with band and eaves courses, define the elevation. Openings feature pointed arches, some with a triple-lobed shape or shoulders; the doorway has roll-moulded detailing; the porch and gables incorporate buttresses; and voussoirs and stone mullions are also present.

The south-east (principal) elevation is symmetrical. The central bay has a gabled porch with buttressed corners and a pointed-arch doorway. Above the doorway is a carved band with the words 'THE GREIG INSTITUTE' and a shield dated 1872 in the gablehead. The doorway itself has a pair of timber panelled doors and a decoratively-patterned fanlight. A small, shouldered, two-part window is set back on the first floor. The flanking bays each have slightly projecting full-height gables; tripartite windows are present on the ground floor with individual triple-lobed heads and moulded stop-chamfering, and further tripartite windows above with colonnette mullions, pointed-arch outer framing and carved shield detail to the top of the window (typanum). A single-storey extension is attached to the outer left.

The north-east (Forth Street) elevation contains four windows with pointed-arch surrounds on the ground floor and a further window in the gablehead to the left, all of which are partially blocked.

The north-west elevation features a slightly projecting rounded bay in the centre with a window on the ground floor and a tall tripartite window above. Piend-roofed bays flank the central bay; the left bay has a door and two narrow windows at ground level, and a pointed-arch tripartite window breaking the eaves above. The bay to the right of centre has a door and two vertically-aligned windows, with a tripartite window to the first floor similar to those on the south-east elevation. A single-storey extension is attached to the outer right.

The south-west elevation includes a single-storey extension projecting at ground level, and a gabled bay to the right with a partially blocked two-part window in the gablehead.

The windows are timber sash and case with plate glass glazing; the windows in the centre bay at the rear have been altered. The roof is covered in grey slates. The gablehead stacks have coped, shouldered and harled details; the ashlar-coped skews have roll-moulded skewputts. Cast-iron downpipes with decorative rainwater hoppers, and decorative cast-iron finials are also present.

Inside, the interior features plain cornicing, a timber-balustered dog-leg staircase, and boarded timber dadoes. A pointed-arch commemorative panel is located on the ground floor. Low, ashlar-coped, rock-faced boundary walls enclose the site.
