Welcome to 15 Old Gulph Road, an architectural masterpiece in a serene, private location set amidst 1.69 exquisitely landscaped, gated acres featuring over $350,000 in recent enhancements by the current owners. This extraordinary residence is a rare fusion of classic architecture and timeless design with a flexible layout to accommodate any lifestyle. Redesigned in 2012 by celebrated architect Carlas Valhonrat, protégé and colleague of Louis I. Kahn, the home represents a perfect harmony between nature and structure, serenity and sophistication. The unsurpassed beauty of the landscaped gardens generates a peaceful energy that carries forward as you enter the home. The home's design emphasizes light and openness, with floor-to-ceiling windows, wide balconies, secret walled patios, and five fireplaces on the entry floor anchoring the expansive, open-concept living spaces carefully designed to offer stunning views from every window and filling the home with abundant natural light. The main house offers 5-6 bedrooms and 6 full baths, including a luxurious Primary Suite with dual baths, featuring both steam and traditional showers, extensive custom designed closet space, and a third-level dressing room/cedar closet featuring a motorized dry-cleaning-style hanging system. Each secondary bedroom enjoys its own en suite renovated bath, showcasing classic materials used in imaginative ways. A third level on one side of the home offers two bedrooms and full bath while a separate third floor space above the Primary Suite offers an additional Bedroom and full Bath, ideal as a Private Study or Professional Home Gym. The main floor features rich hardwood flooring throughout and a fabulous Kitchen, Breakfast Room & Family Room area that serves as the heart of the home offering. The Outdoor Living Area is equally impressive and truly a gardener's dream featuring lush new landscaping, mature specimen plantings, new exterior lighting, and a new awning on the lower terrace. A circular inlaid courtyard leads to a two-car garage topped by a charming in-law/au-pair suite with Kitchenette, full Bath, walk-in Closet, Laundry and generous storage. A separate 3-4 car garage with private gated access from Old Gulph Road provides additional space for collectors or enthusiasts and provides the perfect blank canvas to create additional future living space, perhaps a Guest Cottage.
