Step into a piece of history upon entering this stunning mansion on private and prestigious Washington Terrace, a street in the National Register of Historic Places and a St. Louis City Landmark. This 1903 Second Renaissance Revival masterpiece, designed by architects Weber & Groves, perfectly blends grand architectural heritage with refined modern amenities. Upon arrival, the stately portico columned entrance flanked by guardian lions sets a tone of timeless elegance, continued with a classic porte-cochere over the side door entrance—a rare architectural touch that provides both style and sheltered convenience. Spanning an impressive 9,667 square feet, this 18-room historic landmark offers an expansive floor plan designed for both grand-scale entertaining and sophisticated everyday living. The elegant foyer leaves you in awe as your eyes take in the beauty of glistening refinished hardwood floors and old-world early 20th century ornate craftsmanship. Exquisite Arabesque carvings in a rich, dark finish adorn the wood throughout the entryway and staircase. The home’s heritage is preserved through 10 sets of pocket doors and 9 hand carved fireplace mantels distributed across all three levels. On the main level you’ll find a parlor with hand carved cherub embellishments on the massive mantel, intricate ornate crown molding and floor to ceiling windows, a library with original built-in desk/bookcases and an ornate ceiling border, a living room with exquisite crown molding and the original non-electric candle chandelier, a curved solarium with access to the private courtyard, a formal dining room with a sparkling Waterford crystal chandelier as its focal point, and a Chef’s Masterpiece Gourmet kitchen - a stunning blend of historic charm and modern conveniences. Featuring a hearth room, brick walls, tall arched windows, and granite countertops, it is fully equipped with premium appliances: a Gaggenau cooktop, Subzero refrigeration, Electrolux double ovens, and a Bosch dishwasher. A separate coffee/wet bar with a beverage refrigerator and a dedicated breakfast seating area complete the kitchen. The beautiful Grand Staircase includes a curved window seat with leaded glass soaring to the ceiling and leads you to the 2nd floor Grand Landing highlighted by 2 stunning crystal chandeliers. From there, step out onto the front balcony and enjoy the view of this historic street. The Primary Suite includes a Powder/Dressing Room with 2 walk-in closets, as well as an ensuite bath with built-in closets and access to the side balcony. Also on the 2nd floor, you'll find 3 more bedrooms, and 2 original marble bathrooms. The 3rd floor boasts an additional 3 bedrooms, a full bath, and a craft/hobby room, as well as a media room and a ballroom/recreation room, both ideal for grand entertaining. A 4th level of space - the attic - accessible from the media room, has 15-foot ceilings and has been used as a roller-skating rink in the past with a disco ball at its center. For relaxation, the home offers 4 private balconies—including one overlooking the pool—and two featuring newly installed copper flooring. All of this space, plus central air-conditioning (3 new condensers installed in 2025) and radiant heat throughout the home, offer ample space for family and guests to retreat in comfort. Outside, the grandeur continues with a 3-car garage equipped with EV chargers, an in-ground, heated, saltwater pool, a wraparound porch with hot tub and a beautiful English garden/courtyard adjacent to the curved solarium – areas all perfect for entertaining. A home of this scale and pedigree is a rare find. Over $1 million has been put into the home since the current owner purchased it in June of 2021, with most of the improvements being done in the past 2 years. Don’t miss your chance to own this Grand, Magnificent Masterpiece!
