It originated as the Lamb Tavern on the Philadelphia-Lancaster Turnpike and was later converted into a residence.","why_significant":"The nomination argues the house is significant for its early tavern use along the Philadelphia-Lancaster Turnpike, for its association with several Pennsylvania architects including Addison Hutton and R. Brognard Okie, and for its long occupancy by prominent owners. It is also described as the only surviving building from the village of Glassley.","narrative":"Roughwood is a two-story house in Devon, Pennsylvania, built in stages beginning around 1805 and most likely 1819 for the stone wing, which was constructed over a earlier log structure whose timbers were salvaged from the 1722 Great Valley Baptist Church. The stone wing served as the best quarters of the Lamb Tavern, which was licensed in 1812 by order of Governor Simon Snyder, an unusual route in Pennsylvania. The property is significant as one of the few surviving tavern buildings on the Philadelphia-Lancaster Turnpike and for its architectural layers, particularly the 1928-1930 remodeling by R. Brognard Okie, who copied interior details from the tavern period. Later owners included publisher Peter W. Ziegler, banker Thomas Alexander Biddle and shipping executive Colonel Michael Dallett, whose family held the house until 1941.","period_of_significance":"1805-1939","architect_builder":"Addison Hutton (renovation work 1868-1872, attributed circumstantially); R.
