About this home

Gracing one of the most prestigious locales in all the Lehigh Valley is a bright, airy and inviting cape cod beautifully sited on 2.67 rolling acres high above Saucon Creek. The family room is illuminated by a wall of windows crowned by a bold glass arch giving stunning vistas of Saucon Valley. Well-executed cabinetry flanks a floor-to-cathedral ceiling brick fireplace. The open floor plan flows to a bright custom kitchen with ample Corian counters providing vast workspace. The dining room displays superb moldings and French doors that lead through the hall to the living room. Two bedrooms on the main floor include a master bedroom suite - a sought after luxury. The bright garden level recreation room opens to a slate terrace. A game room, bedroom, bath and attached garden garage complete this level which overlooks the extensive lawns. Access to the second floor is via a broad, open stairway leading to a comfortable library and yet another bedroom and full bath.
