About this home

A secluded, wooded hillside is the setting for this one-of-a-kind home originally designed as a Mid-Century classic by Edward Robinson. It was redesigned for the 21st century by Main Line architect Paul Bloomfield as his family's private residence. This is a truly unique home, with soaring spaces and an open plan filled with natural light and modern details throughout. The main level was expanded with 13' high ceilings and blends seamlessly with the outdoors, offering comfortable daily life and a great place for entertaining. A floating stair leads to a new upper level that offers flexible space with beautiful views and more connections to the exterior including a private roof deck overlooking the woods. Recent updates include a new metal roof and an expansive tile patio in the front of the home with a gas fire pit. Perfect for al-fresco parties. Don't miss this one-of-a-kind home. This home feeds Ithan Elementary School, the wonderful public school that is a joyful place to go to school. The House was expanded and fully renovated in 2008. Some details have been recently updated. The home has new wood floors on the main level. All personal items fish, furniture, antlers, the tv in the main room & workbench in the garage is excluded
