Masonic Lodge, 129 High Street, Dalkeith

The Masonic Lodge at 129 High Street, Dalkeith, was designed by Currie, Scott & Young in 1766, with significant additions made in 1939. It is a single-storey, four-bay rectangular building constructed from sandstone rubble, with some areas harled and featuring polished raised margins.

The southeast elevation is obscured by the flat-roofed additions from 1939. The northeast elevation was not visible in 2000. The northwest elevation is partially hidden by a harled addition on the left, while the right side has a window in the flanking bay that has been infilled with brick. The southwest elevation is harled and includes a doorway on the left with sandstone infill, three regularly placed window openings to the right, all infilled with harling, and a piend-roofed addition on the outer right.

Most window openings in the lodge have been infilled. The roof is piended, covered with graded grey slate, and features lead ridges and inset louvred ventilators. The rainwater goods are made of PVCu and cast iron.

Inside, the principal room has a rectangular plan and a boarded floor that covers the original flooring. There is a panelled timber door on the northeast side, with a small round-arched recess to the left, which is said to lead to a bottomless pit. To the right of the doorway is a depressed-arched niche housing a statue of St Andrew, created by Sir John Steele in 1827, with a stained glass memorial window opposite. A segmental-arched niche is located to the southeast, featuring a hexagonal sounding board that oversails. The ceiling is coombed with plaster cornices. A datestone from the lodge, reading "1766," is set into the wall of the 1939 addition.
