View from the Entrance:

 
The floor plan is quite common to other Calvinistic Meeting Houses of the period in the Colonies and the British Isles.Our Calvinist "New Side"forbears were strict Iconoclasts; you will notice there is no ornamentation
.
The boxed pews on the ground floor were rented by subscription annually to families. These monies provided the bulk of the congregation's annual operating funds.

Note the rounded arches over the doors and windows (Palladian) marking this as a Georgian-style structure. (A portrait of the George in question,George II, hangs in the rear of the church, next to the founding royal charter dated 1742.)
All pews were aligned to the focal point of Calvinist worship, the pulpit. Note the elegant "wine stem" double pulpit and lower presenter's desk.
