Robert W. Gibson designed the church following the design of the 1606 Vleeshal in Haarlem, The Netherlands. Authenticity is enhanced by the choice of long, thin, brown bricks laid in Roman pattern, and by the generous use of quoins and blockings of buff terra cotta. The architect further enhanced the antique effect by inserting several handsome, terra cotta panels carved with the coats-of-arms of the church and of past benefactors. The large, octagonal pulpit is carved from oak. Its panels show the coat-of-arms of the Dutch Reformed Church and the great seal of the Church. The pulpit chairs are carved of oak in Old Dutch style. The stained glass windows were donated and created over the course of several decades; three are by Tiffany studios.
