St Leonards Episcopal Church, Dobbies Road, Bonnyrigg

St Leonards Episcopal Church, built in 1890 by Hippolyte J Blanc, is a cruciform hall church with a chancel added in 1894. The church is constructed of snecked bull-faced ashlar sandstone with polished and droved ashlar dressings. Lancet windows and long and short quoins are notable features, alongside a rectangular rendered church hall to the southeast.

The principal southwest elevation features a hood mould above a tall, point-arched, tripartite window with a central light. Clasping gabletted buttresses mark the terminals, and a gablehead belfry contains a bell. The southeast entrance elevation is five bays wide, with a projecting single bay transept to the right of centre. A hood-mould with label stops sits above a moulded, round-arched doorway, with a deep-set, two-leaf boarded door to the outer left. Single windows are placed in each of the remaining bays. The transept incorporates a hood-mould above a bipartite window with an oculus, an ashlar cylindrical stack, a boarded door flanked by windows to the left return, and a single window to the right return. A bipartite window with a circular pane is situated in the outer right bay. The northwest side elevation has six bays, with a slightly advanced four-bay original block on the right. A tall, gabled incomplete transept protrudes to the left of centre, incorporating a blinded slit window to the gablehead. A bipartite window with a circular pane is to the outer left, with single windows to the remaining bays. The gabled northeast rear elevation features a hood mould above a tripartite, pointed arch with trefoil plate tracery and a shorter central light, as well as a quinfoil window above. Buttresses are positioned at the outer left and right edges. A Latin cross is set into the gablehead. A single window is to the left projection.

The church contains leaded stained glass windows. The roof is covered with grey/green slate, featuring terracotta ridge tiles and vents, with ashlar coped skews. Decorative cast-iron rainwater goods are affixed with decorative brackets.

Internally, the 1997 assessment revealed a timber boarded roof with exposed arched bracing. The added chancel to the northeast has a timber panelled barrel vault reaching dado rail height, a stone chancel arch, stone transept arches to the side walls of the chancel, and a timber panelled altar with a tripartite window above to the northeast wall. A point-arched tripartite stained glass window, manufactured by Mayer & Co, Munich and London in 1890, is positioned on the southwest side. A stained glass window, created by William Wilson in 1961, is situated on the southeast side. Other features include a portable font, timber pews and chair stalls, and a decorative timber gothic organ case set within the southeast transept.
