Gate Lodge, Olrig House

The Gate Lodge at Olrig House is a unique single-storey and attic building from the later 19th century. It features an asymmetrical gabled design constructed from coursed stugged rubble with tooled dressings, some of which are painted in contrasting courses.

The northwest elevation, which faces the entrance drive, has a projecting gabled porch that includes a ribbed and studded door with decorative cast-iron hinges. To the left of the porch is a window, and above it is a boldly gabled dormer. There is also a round window set in the ground floor at the canted north angle. On the northeast side, a lean-to porch with a leaded roof has a small round-headed attic window in the centre gable above. The southwest gable features a rectangular bay window beneath a fishscale slated lean-to roof, with a small corbelled oriel above. The windows are fitted with 4- and 6-pane glazing.

Distinctive architectural details include unusual projecting alternating quoin detailing at all angles, ornate bargeboards, and decorative cast-iron ridge cresting. The building has tall paired end stacks with string courses and cornices, rising from a slate roof.

The gate piers consist of a pair of square, coursed dressed rubble piers topped with corbelled pyramidal caps. These are linked by low coursed rubble quadrants to similar piers. The original cast-iron railings have been replaced by modern pierced concrete walling.
