Why it's listed
Chestnut Hill is a residential neighborhood in northwest Philadelphia with more than 2,600 buildings, most of them single-family houses of two or three stories. Settlement began in the early 1700s along Germantown Pike and Bethlehem Pike, and the arrival of the Philadelphia, Germantown and Norristown Railroad in 1854 turned the village into a summer retreat. Later, the Pennsylvania Railroad extension in 1884 prompted Henry Howard Houston's planned western section, and Dr. George Woodward's work from 1904 added courtyard housing and landscaped streets. Local Wissahickon schist stone is the common material throughout, and many houses are set into the land along the Wissahickon and Cresheim valleys. The district is listed for its architecture, its wide range of styles by leading Philadelphia architects, and its planning, which followed the natural contours of the land. Much of the surrounding valley was later preserved as parkland.
Significance in brief: The nomination argues that the district is an uncommon assemblage of most residential styles found in the Philadelphia region, with work by nearly every major Philadelphia architect or firm. Its buildings are unified by human scale, the pervasive use of local Wissahickon schist stone, and landscaping tied to the Wissahickon Valley. Its community planning followed the natural land contours, shaped significantly by Henry Howard Houston and Dr. George Woodward.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
