Photo credit: Peter Aaron/OttoThis architecturally significant residence at 51 Old Stone Hill Road in Pound Ridge, New York, was designed by renowned firm Kieran Timberlake. Sheltered by the woods, this rare example of modern architecture sits high on a secluded knoll.

Glass walls and reflective surfaces aside, the home was designed to be energy efficient with every possible comfort. [Listing details: 51 Old Stone Hill Road by Brian Milton of Compass]RELATED:
