Kentuck Knob, National Historic Landmark residence in Chalkhill, United States.
Description
Kentuck Knob is a private residence in Chalkhill, Pennsylvania, recognized as a National Historic Landmark and situated on a wooded hilltop in the Allegheny Mountains. The curved form of the building uses red cypress wood and local sandstone, with large glass surfaces offering views of the surrounding forest and valleys.
History
Frank Lloyd Wright designed the house in 1954 for Isaac Newton and Bernardine Hagan, a couple from the region. Construction was completed two years later, following the principles of Usonian homes that Wright developed for middle-class Americans.
Culture
The name Kentuck Knob comes from the site's location on a hilltop where Kentuck oaks once grew in the Allegheny Mountains. Visitors today see how the open living spaces flow seamlessly into the terraces, with the building following the natural contour of the hillside.
Practical
Guided tours run from March through November between 9 AM and 4 PM, with Wednesday tours starting at noon. The house sits on a ridge and requires sturdy footwear, as paths cross uneven terrain.
Did you know?
The entire building is based on a module of equilateral triangles that runs through walls, floors, and windows. This geometric foundation shapes every room and creates angles that direct views outward and distribute light in different directions.
