Welcome to Dupont Circle, where this stunningly renovated townhouse and English basement offers unparalleled luxury and a modern-day vision of what's possible in this historic neighborhood. The home's central location, where the circle's iconic stone fountain is visible from the sidewalk, makes for an easy stroll to The Phillips Collection, Embassy Row, art galleries, restaurants, and the Dupont Circle Metro. But it might be hard to leave the tailored French pea-gravel terrace out front, or the top-of-the-line amenities and architectural details that beckon from a renovation overseen by Thomson & Cooke Architects and interior designer Martha Vicas. Behind a lovingly restored 19th-century facade, classic design mingles effortlessly with modern function. The kitchen is a particular standout, starring the custom-colored LaCanche range. Rhodonite countertops resemble a watercolor painting over custom cabinetry accented with sculptural, brushed-brass pulls. Sub-Zero and Miele appliances hide behind custom paneling, and a framed-glass door reveals the 120-bottle wine tower. Designer finishes abound, from 3-inch rift and quarter-sawn white-oak floors to Ann Sacks and Waterworks tile in the bathrooms. Architectural delights include elliptical stairs that seem to float free from the walls as they wind upwards, illuminated by a shaft of sunshine streaming from a skylight at the top. At night, globe-shaped lights affixed to the walls and hanging from the ceiling resemble an art installation, turning a simple trip upstairs into a sensory experience. High-end lighting by Holly Hunt and Roll & Hill, among other top-flight brands, fills the rest of the house. The design team also specified decorative paneling in the living room and built-in glass-enclosed shelving in the den that flanks a fireplace trimmed in champagne limestone. The home is an intimate enclave due to new foam insulation and sound-attenuation throughout, which is especially nice for sleeping in bedrooms whose windows are dressed in blackout draperies. The master suite is an especially cozy retreat with a large custom walk-in closet and a luxurious bathroom with a frameless glass-enclosed soaking tub and shower. A lower-level English basement is filled with light from large front windows that enclose a dining nook that's open to the living area. Contemporary polished concrete floors fill the two-bedroom unit, which features an open kitchen with stainless appliances and marble counters. It's hard to top this property for the finest in world-class urban living.
