Idlewild is a historic building near Media, Pennsylvania, designed by the Victorian-era Philadelphia architect Frank Furness as a summer cottage for his family.

This increases the privacy of the rooms behind, and the visual interplay between the differing scales of the "service tower" and main house gives vibrancy to the façade.

In the library, the architect placed the grand staircase in a tower at the front, separating circulation to the building's upper stories from the reading rooms behind.

"[6] See main article: Frank Furness "Idlewild" is located at the top of Gayley Hill in Upper Providence Township just south of the borough of Media.

This was a mile west of "Lindenshade," the Wallingford summer house of his brother, Shakespearean scholar Horace Howard Furness.
