In Georgetown, a turn-of-the-century townhouse has been transformed into something more akin to a private compound, with multiple structures arranged around a central courtyard, a swimming pool, and a level of privacy rarely found in the tightly knit neighborhood.

The property is reportedly owned by Mark Penn—the Stagwell CEO, former Microsoft executive, and longtime political strategist—and his wife, Nancy. The couple bought the property in 2003 from former U.S. ambassador to Belgium Alan Blinken for $5.175 million and completed a comprehensive renovation in 2019, according to the Washington Business Journal. Daniel Heider of TTR Sotheby’s International Realty is representing the listing.

Originally built in 1900, the urban compound now spans about 7,200 square feet across a main residence and a spacious guesthouse with a combined seven bedrooms and five-and-a-half bathrooms. Updates retained elements of the traditional layout—ample formal living and dining rooms with fireplaces opening off of the foyer—while opening up the overall flow.

The kitchen is outfitted with Wolf and Sub-Zero appliances, multiple refrigeration zones, dual wine storage, and a breakfast area with its own fireplace. French doors lead directly to the central courtyard. That outdoor space includes expansive stone patios, an outdoor kitchen, and a lap pool with an automatic cover—features more typical of larger standalone homes in the suburbs than a Georgetown row house.

The primary suite is contained within its own wing on the second floor, with two walk-in closets and a bath with a skylight, soaking tub, and separate water closets. Four additional bedrooms (two with private baths) are spread across the second and third floors, while the lower level includes a recreation room, a mirrored gym, a laundry room, and a theater with seating for eight. The guesthouse, accessible internally or via a separate entrance, includes its own living space with a fireplace and wet bar/kitchenette, bedrooms, and two potential bathrooms, with shared access to a bath, along with a two-car garage with EV charging.

Penn founded The Stagwell Group in Washington, D.C., in 2015 and took the company public in 2021 through a merger with MDC Partners. Stagwell reported nearly $2.5 billion in revenue in 2025 and recently acquired its D.C. office building for $7.5 million, according to the outlet.

The property also lands as Washington’s luxury market continues to draw a new class of buyer. As Robb Report previously reported, billionaires, tech executives, and political power players have been increasingly buying into the capital city, driving demand for homes that offer privacy, space, and proximity to power.
