3117 O STREET NW, WASHINGTON, DC 20007

$14,995,000

Set along one of Georgetown's most established residential blocks, 3117-3121 O Street NW presents a rare townhome compound offering exceptional scale, privacy, and versatility. Originally built in 1900 and comprehensively remodeled in 2019, the property encompasses approximately 7,200 square feet across a primary residence and a fully integrated guest house.… Read More The main residence honors classic Georgetown architecture while delivering a highly livable, thoughtfully modernized layout. Formal living and dining rooms anchor the main level, each defined by fireplaces and gracious proportions. The kitchen opens directly to the central courtyard through French doors, creating a seamless flow between interior and exterior spaces. Designed for both everyday living and entertaining, the kitchen is outfitted with Wolf and Sub-Zero appliances, multiple refrigeration zones, dual wine storage, and a breakfast area with its own fireplace. Outdoor living is a defining feature of the property. The private, landscaped courtyard is centered around a lap pool with an automatic cover and is complemented by fountains, flagstone patios, and an outdoor kitchen, forming a tranquil retreat rarely found in the heart of the city. The upper levels of the main house are anchored by a dedicated primary suite wing featuring dual walk-in closets and a spa-style bath with a skylight, soaking tub, and dual water closets. Additional bedrooms span the upper floors, many with fireplaces, offering flexibility for guest accommodations, home offices, or private studies. The lower level is equally well-considered and includes a recreation room, gym, theater with seating for eight, and a laundry room. The guest house, accessible both internally through the lower level and via a separate exterior entrance, adds a meaningful layer of adaptability. With its own living space, kitchenette, bedrooms, bathrooms, and direct garage access, it functions seamlessly as guest quarters, extended family accommodations, or a private work-from-home residence. A two-car attached garage with EV charging, along with additional driveway parking, further distinguishes the offering and provides a level of convenience seldom found in Georgetown. Throughout the home, systems and infrastructure have been carefully curated, including multi-zone HVAC, whole-house audio, automated blinds, integrated home automation, and security systems. Defined by scale, outdoor living, and flexibility, 3117-3121 O Street NW represents a rare opportunity to own a timeless Georgetown compound designed for modern city living. Read Less
