Prominently situated on revered Kalorama Circle, directly adjacent to the French Ambassador’s residence, is number 78. A Neo-Palladian Revival residence constructed at the height of the Roaring 20s and painstakingly restored over the years. A stately, symmetrical facade, honed from limestone and brick, is sparingly embellished by cornice work and rosettes, creating a subtle elegance while harkening back to a bygone era of master craftsmanship. The restrained entrance reveals an elegant gallery-style greeting hall, with gleaming inlaid marble floors and accent lighting converging around the dramatic central staircase spanning all four levels, bathed in natural light from the large skylight above. A private office, access to a shady pea gravel sculpture garden, glass-enclosed wine room, and staff quarters are thoughtfully positioned on this level.   The main level’s effortless flow is enhanced by towering ceilings. Here, embassy-sized formal spaces are clad with parquet flooring and intricate plasterwork, enabling entertaining on a level of grandeur reminiscent of Washington’s Gilded Age. Fireplaces in both formal living and dining rooms add warmth and anchor these elegant spaces, while a private library is discreetly tucked away with access to the rear terrace. The contemporary chef’s kitchen is a refreshing contrast: sleek European-style cabinetry and a full complement of professional-grade stainless steel appliances are centerpieces of a space that can be fully opened to the outdoors.   The principal suite occupies almost an entire level. A sitting area with a fireplace and integrated bookshelf is an artful addition to the oasis, served by two sumptuous baths and dressing rooms. A sunroom boasts verdant wraparound views of leafy treetops and neighboring gardens via panoramic windows. The scenic vista is also shared by the top level’s observation deck. A central family room is flanked by two spacious bedrooms, each featuring a luxurious ensuite bath. An oversized, attached garage and a large, private motor court complete the offering. Stunningly authentic yet inventively modern, 78 presides as one of the great homes of Kalorama, one of the city’s most established neighborhoods and unquestionably one of Washington’s premier offerings.
