Sts. Peter and Paul Ukrainian Orthodox Church

• the crossroads setting near the western edge of Sundown and the building's traditional east-west alignment, set back from roadways within a large grassed and treed plot
• the free-standing wooden bell tower, two-tiered, with hip roofs, louvred openings, cupola, etc.

Key external elements that define the building as a fine interpretation of traditional Western Ukrainian church design include:

• the boxy, tiered cruciform massing on a low concrete foundation, including the twin-towered front, short cross-gabled transepts and polygonal apse surmounted by a large central dome, and two lower volumes, a one-storey entrance porch with a gable roof and a sacristy with a shallow hip roof
• the symbolic trio of metal-clad banyas (onion domes) topped by three-bar Eastern crosses, including the main dome and cupola on an octagonal drum and the smaller tower domes
• the orderly arrangement of round-arched sash and fixed windows with clear glass and painted wood transoms throughout
• the unpretentious materials and finishes, including stucco cladding over walls of milled lumber, plain wood window surrounds and other trim, the double-door entrance, etc.

Key elements that define the church's liturgical functions and richly decorated interior include:

• the cruciform plan, including the vestibule, open-area nave, transepts, raised east-end sanctuary, west-end loft accessed by a small staircase off the nave, etc.
• the groin vault ceiling opened at the crossing by the broad, well-lit and intricately detailed dome on pendentives
• the painted wood finishes throughout, mostly in light blue with pale trim and contrasting panel and border motifs, including elaborate detailing depicting the heavenly world, faux marble, etc.
• the sanctuary, including the iconostas with royal and deacons' doors, the wooden altar, etc.
• other religious furnishings and features, such as the tetrapod, framed icons, brass chandelier, etc.
