In 1912, vaudevillian Frederick Proctor built a duo of Dutch-style Colonial homes for his two daughters in Larchmont Manor. Over 100 years later, they’re both being offered for sale simultaneously.

Developed as a summer colony, the Westchester coastal neighborhood, with its storied yacht club and Frederick Law Olmsted-designed Manor Park, was as fashionable then as it was today. The Proctor sisters, and their sister houses, couldn’t have been in a better location.

Both 84 (left) and 88 (right) Park Avenue have been extensively renovated and modernized. While the exteriors remain mostly matching, a century’s time and contrasting decorating sensibilities of their respective owners reveal two vastly different interior styles.

88′s kitchen boasts a center island, concrete counters and Calacatta marble backsplash, along with appliances by Bosch, Sub Zero and Wolf. But 84 is on trend in its own right (see No. 2 on this Forbes list), opting for cabinet-free windowed walls and open shelving.

Both screen porches are as relaxing as they ever were.

The best parts of living in either home will never change.
