Brognard Okie is set on a breathtaking 2.5-acre private lot with a terraced lawn and endless views of Gulph Creek and beyond.

With over 100 feet of linear southern exposure, the home boasts gracious sun-filled rooms that flow seamlessly into one another, perfect for entertaining, each space offering large deep-set windows, with two sets of French doors and four additional 16-lite doors leading to multiple terraces and extensive views. High ceilings, beautifully restored original random width pegged floors, incredible millwork, 11 dramatic fireplaces, solid wood interior doors, wrought iron hardware, stunning craftsmanship including Okie designed built-ins and customized expanded spaces throughout the residence hint at the grandeur of yesteryear but perfectly suit todays lifestyles.
