In the heart of one of the most coveted avenues in Westport, this iconic piece of history commonly known as the headquarters to William Phelps Eno and the Eno Foundation in the late 1800's, boasts over 10,000 square feet of unparalleled architectural designs on one acre of land. When you arrive at the property, the terra-cotta brick instantly welcomes you to a classic marble entryway that leaves a remarkable first impression. The existing layout offers 9 generously sized offices, a mail room, 9 closets and additional space that can be re-arranged to meet your needs. Just minutes from I-95 and Metro North and nestled in a desirable residential community makes this a unique opportunity for a discerning buyer. This exquisite mansion is approved as a non-conforming use in a residential zone, but has the opportunity to be converted to a single-family residence.
