An imposing walk-in fireplace is the focal point of the Garden Room, a 20th-century addition to the original building that features wood beams and stone from an icehouse that once stood on the property. This sitting room opens into the dining area, where guests enjoy a full country breakfast, featuring seasonal fresh fruit, freshly baked muffins and a main dish such as waffles, pancakes, omelets or quiche.
Next to the dining area is the kitchen, part of a 19th-century clapboard extension that housed coachman quarters and beehive bake oven. The Pennsbury Inn's original dwelling house was erected in 1714 and made of Brandywine blue-granite rubble stone on acreage purchased from William Penn's commissioners in 1681. It was first enlarged in 1749 with a stone addition; the front facade was done in Flemish bond brick.
