St. Mark's Episcopal Church is located on Main Street in Hoosick Falls, New York, United States.

Several additions and renovations were made to the original building in the decades after its construction, most notably a parish hall in the early 20th century.

The church is on a small lot on the west side of Main Street, just south of a village park and a short distance from the post office opposite.

It is on a small flat lot, set back slightly with a hedge and lawn in front and mature trees around it.

The main entrance has double wood doors with wrought iron decorative hinges and a pointed arch limestone surround.

The second has another lancet on the east and west, the third a clock and the fourth a pointed arch louvered opening with Meneely chimes.

Plaster walls, original pews, a lectern with brass eagle and stained glass from different periods complete the trim.

Dudley also designed and built Wood's Tudor Revival house (no longer extant) on the hillside behind the church.

Most churches designed by Ecclesiologists thus featured steeply pitched roofs, axial plans, and clearly defined separations between the various functional spaces.

It is not known why, although perhaps that material was available in enough quantity in Hoosick Falls at the time to make it economical to build the church of it.
