The meetinghouse had its beginnings as the conventional one-room building of early Quaker design, but within a decade a growing community required the west addition, perhaps to keep up with the new fashion of the Philadelphia Yearly Meeting. Its mason, Willis, had constructed the brick courthouse in Center Square a decade earlier. Significantly, this building follows the Chester County norm of a one-story meeting, rather than the more monumental two-story mode of the Bucks County buildings.
