North Gate Lodge, Riccarton Estate, Heriot Watt University, Edinburgh

North Gate Lodge, located on the Riccarton Estate at Heriot Watt University in Edinburgh, is an early 19th-century building designed in the style of William Burn and David Bryce. This single-storey, gabled T-plan lodge features Jacobethan architectural details. It is constructed from stugged, squared, and snecked sandstone, with polished ashlar dressings, a base course, and projecting eaves. The lodge is adorned with decorative bargeboards, chamfered reveals, sandstone mullions, and transoms, as well as buckle quoins.

On the west elevation, there is a broad bargeboarded gable to the outer right, with a canted window at the center and an ashlar roof with a panelled apron. To the left, there is a slightly advanced, ashlar bargeboarded porch situated in the re-entrant angle, featuring a basket-arched, boarded door and a panel in the gablehead with a modern angle lamp. A small window is located in the left return, with an ashlar transom above. The outer left side has a bipartite window.

The south elevation consists of three bays, with an advanced shouldered flue at the center and narrow windows flanking to the outer left and right.

The north elevation features a square projecting bay at the center, topped with an ashlar roof. The lodge has 8-pane sash and case windows and a stone-slate roof with a diamond pattern at the center of each pitch. A rope-moulded, barley-sugar stack sits on a shouldered base with a shaped coped cap, while a wallhead stack is located to the south, accompanied by a diamond-aligned sandstone stack.

The gatepiers and screen walls consist of panelled ashlar gatepiers with a triglyph panel motif in the frieze, beneath which hangs a masonry bauble on a link, topped with a pyramidal cap. An elaborate perforated screen wall features regularly stacked semi-circular sections on a plain base. Curved quadrant walls made of stugged, coursed sandstone with ashlar slab coping continue to the west, with the lower wall featuring semi-circular coping.
