A true architectural masterpiece, this extraordinary 3.5-acre estate was custom designed and solely owned by a well-known Saint Louis-based architect and offers sweeping, unobstructed views of the Meramec River Valley. With over 6,500 sq. ft. of total living space, this one-of-a-kind home is designed to showcase the landscape with a dramatic wall of windows that spans the main living areas, flooding the interior with natural light and treetop vistas for miles. The main level features a formal dining room, sleek modern kitchen, library, powder room, a two-story great room and two-story family room divided by a see-through fireplace. Above this space sits the private primary suite, featuring a vaulted sleeping area with skylight views of the stars and an en suite bath with freestanding soaking tub and custom walk-in shower. Two additional bedrooms with soaring vaults and a gorgeous second full bath complete this wing. To the left of the entry, discover another vaulted living space on the main level with a wall of glass, slate floors and a second large fireplace, a wide gallery-style hallway, and a stunning mudroom with circular staircase leading to a flexible upper level. This wing includes a fourth bedroom (currently used as an office with Murphy bed), full bath, and a large-sized vaulted bonus space ready for your vision. The walkout lower level offers recreation space, kitchenette, full bath, and storage with additional laundry hookups. A separate exterior entrance leads to a full apartment – complete with kitchen, living room, bedroom, bath, and laundry – ideal for guests, in-laws, or private office/studio use. A four-car garage offers ample parking and an additional parking pad and circular driveway are great for when you entertain. Multiple patios and stone pathways surround the home, creating extensive outdoor living spaces designed for entertaining and enjoying the scenery and breathtaking views. Nestled in Rockwood schools, this rare property blends modern design, architectural significance, and a setting unlike anything else in Wildwood.
