outbuildings at Pennsbury, as a home for a house museum dedicated to Penn. Completed in 1940, it is operated as Pennsbury Manor by the Pennsylvania Historical and Museum Commission in association with The Pennsbury Society, a non-profit organization, and is open to the public. Additional acreage has been acquired enlarging the site . The manor and grounds were listed on the National Register of Historic Places in 1969. Reconstruction Penn wrote to his overseer James Harrison frequently from England during the construction of the estate, providing insight into his intentions and progress of the project. During its early years of ownership the Pennsylvania Historical Commission conducted site mapping, archaeology, and documentary research. In 1934 historian Albert Cook Myers found the buried foundations of the house and a crude drawing on an eighteenth-century survey map. These served as the basis for recreating a typical red-brick manor house on the property. Pennsbury Manor was designed by local architect R. Brognard Okie, (1875-1945), known for his sensitive Colonial Revival constructions in the area, and restoration of the Betsy Ross House in Philadelphia. It appears to today's analysts that he designed a larger and more elaborate house than the original Pennsbury, believed to have been based on a T-shape. Pennsbury Manor was built 1938–1940. Okie's design decisions drew from other properties of that period in nearby Pennsylvania, asserting that Pennsbury probably influenced their design. The result is two stories, with a dormered hipped roof serving as an attic. The design is Georgian influenced Colonial Revival, five bays wide and two piles deep. A white wooden door and windows contrast against red brick laid in an English bond. Support buildings in either matching brick or whitewashed wood frames surround the home. Early anachronisms that were part of the original construction project, such as a white picket fence and brick walkways, have been replaced by more appropriate styles of pale fencing and graveled walks. Bricks were too expensive at the time of Pennsbury Manor's original construction to be used for walkways, and not even the original house was fully constructed in brick. Since the late 20th century the museum staff has concentrated their attentions indoors, creating an increasingly accurate depiction of domestic life in Penn's time through interpretive programs and such decorative elements as period appropriate wall colors, textiles, and furniture arrangements." Okie did not get the final contract for the landscape, but had submitted a
