St. Andrew's is one of the most notable examples of the Stick Style in Vermont. It marks a rationalization of Wentworth's Richard Upjohn–inspired Gothic Revival compositional elements seen in his earlier St. Luke's in Chester (1871). The steeply gabled nave is fronted by a chancel, flanked by a recessed vestry ell to the north and square tower to the south. To the southwest is a small gabled entrance. Stepped wooden buttresses strengthen corners and brace the building's sides. At St. Andrew's these forms are bound (if not altogether coordinated) by a web of Stick Style polychromed framing in the pro jecting gable of the chancel and the gablets of the flared spire. Rafter tails and brackets mark the eaves. Wooden belt courses break the wall surfaces into a patchwork of variously textured siding: clapboarding, a board-and-batten dado, flush vertical sheathing on the tower, and a scalloped version of the same in the chancel's gable. The inherent angularity is echoed by windows and doors that mix angle-headed openings with more typical Gothic lancet forms. The emphasis on frame and texture continues in an interior of hammer beams and patterned boarding. In this more mature Wentworth design, complex form and decoration gain logic and unity from materials and construction.
