• Stories of the families and craftspeople who built Chestnut Hill

• Preservation efforts that keep this neighborhood thriving

• Hidden details and features you might otherwise overlook

Gregory J. Scott is a Fellow of the American Institute of Architects and partner emeritus at RLPS Architects. A seasoned columnist for LNP News and a dedicated preservationist, Gregg has twice received the prestigious Smedley Award from the Historic Preservation Trust of Lancaster County. His expertise and passion for architectural history have drawn sold-out crowds, including his 2018 presentation on Urban at LancasterHistory and his more recent talk on architect James H. Warner.

Scott is also the author of two acclaimed books about C. Emlen Urban. His first book, Urban Legend, highlights 25 of Urban’s architectural masterpieces that left an indelible mark on the City of Lancaster. Based on seven years of meticulous research, Scott draws from Urban’s personal travel diaries, sketchbooks, and linen drawings to track his progression through seventeen different design styles and eleven building types.

In his second book, Urban Alphabet: The Work of C. Emlen Urban A-Z, Scott celebrates Urban’s architectural influence through Lancaster’s first architectural dictionary. This innovative book connects each letter of the alphabet to architectural terms found in Urban’s buildings, offering readers a deeper appreciation of the beauty and intricacies of Urban’s designs. From remarkable details to bold stylistic choices, Urban Alphabet showcases the mastery and vision of the architect who defined Lancaster’s landscape from 1885 to 1935.
