About This Property

The Duncan Penthouse | Where Historic Charm Meets Modern Urban Living Experience boutique living at its best in this rare two-level, three-bedroom, three-bath penthouse at The Duncan, an exclusive nine-residence condominium steeped in architectural history. Originally built in 1906 by Hornblower & Marshall and reimagined for contemporary living, The Duncan offers a perfect balance of timeless craftsmanship and modern sophistication. Residence 401 impresses from the moment you enter — with 15-foot vaulted ceilings, dramatic natural light from three exposures and skylights, and warm maple flooring throughout. The spacious living area centers around a wood-burning fireplace, creating the perfect backdrop for elegant entertaining or quiet evenings at home. The chef's kitchen showcases Sub-Zero and Wolf appliances, wrap-around cabinetry, and expansive prep space, seamlessly connecting to the living and dining areas. Two wet bars, each with a wine cooler — one on the main level and another off the private roof terrace — make entertaining effortless indoors or out. The primary suite offers a serene escape with radiant-heated bathroom floors, generous closets, and abundant natural light. Two additional bedrooms and full baths provide flexible space for guests, work, or leisure. Enjoy panoramic city views from your private roof deck — ideal for al fresco dining or sunset cocktails. Additional amenities include secure garage parking, private storage, in-unit laundry, elevator access, and pet-friendly living. Perfectly positioned in the heart of Dupont Circle, The Duncan Penthouse puts you steps from the Red Line Metro, acclaimed restaurants, cafés, shops, and vibrant nightlife. With a Walk Score of 98, this penthouse combines rare privacy, refined scale, and one of DC's most coveted addresses.
