The James Foster House at 46 Summer Street was built in 1720. The roofline shows that it was once a smaller house, later doubled in size and remodeled to appear Georgian, with the two chimneys, dormers and a symmetrical front. He bought this former orchard land from Nathaniel Clark who moved to Newbury.
The original frame is exposed in places and the chimney girt in the southeast first floor room has simple beveled lamb’s tongue chamfer stops. On the second floor is a rare 2-panel door. Except for the mid-18th century stairs, much early material is concealed.
James Poster was the first postmaster of Ipswich and a Deacon of the South Parish.
