Set at the end of exclusive Monk Road on the cul-de-sac, this Midcentury Modern masterpiece by noted architect Irwin Stein is a rare expression of thoughtful design, natural beauty, and timeless livability in the heart of Gladwyne. Built into a picturesque hillside overlooking wooded surroundings above the Schuylkill River, the residence embraces its setting through expansive glass, abundant exposures, and a seamless connection to landscape from nearly every room. The dynamic "folded plate" roof, a signature of Steins, appears to float above the home. A paved patio leads to the ground-level entrance, where a bright and welcoming foyer immediately showcases the home's generous proportions and architectural character. Original details blend effortlessly with tasteful updates, while Stein’s signature approach to light and sightlines is evident throughout—framing mature trees, natural foliage, and long views at every turn. The main level offers an ideal everyday layout. The primary suite is privately positioned and includes an ensuite bath and copious closets. Two additional bedrooms on this floor enjoy large windows, tranquil views of the property, and share a full hall bathroom. Nearby, the updated kitchen, clad on three sides with original Walnut boards, features granite countertops, stainless steel appliances, and an electric cooktop, while the adjacent dining room is perfectly placed for both casual meals and entertaining. There is also an expansive, sunken living room highlighted by a fireplace, butt-glazed corner glass windows and a surrounding deck. Downstairs, a more intimate family room creates a warm and inviting gathering space centered around a cozy fireplace. Designed for entertaining and relaxed living alike, this level also includes two additional well-sized bedrooms sharing a full hall bath, offering flexibility for guests, offices, or fitness needs. There is also an expansive bonus room ready to be made into a home gym or craft center and the original bomb shelter (the home was designed in the sixties!) ready to be converted into a wine cellar. Glass doors open directly onto an organically shaped custom patio with unique rock formations that catch the water as it plunges from the roof on rainy days; it's where the home’s indoor-outdoor lifestyle truly shines. A few steps down into the yard, a heated in-ground pool set against a dramatic stone wall provides the perfect summer retreat. Completing the property is a covered carport equipped with a Tesla electric charger, thoughtfully integrated for modern convenience. Surrounded by wooded scenery and elevated river views, this exceptional residence offers a rare opportunity to own a true architectural gem in one of the Main Line’s most coveted settings.
