The architectural composition of Saint Andrew’s Church is distinctive and picturesque in the Gothic manner. Constructed of rock faced granite, the Church’s rugged appearance has a solid quality and great dignity.
The interesting massing of structural elements culminates in a handsome clock tower, adjacent to the south transept on 127th Street. Two graceful pointed-arch openings on each side of the belfry give form and deep shadow to the tower, while the slate-covered spire is adorned at each corner by delicate turrets. Cruciform in shape, the plan has galleries in the transept and side aisles in the nave. Simple buttresses, at the exterior of the south aisle wall, lend structural support and considerable interest to the design.
