Billionaire NFL Owner Pays Record $28 Million for DC House

Billionaire Joshua Harris, owner of the Washington Commanders, has paid $28 million for one of Washington, D.C.’s most historic homes, setting a price record for the city.

Harris and his wife Marjorie plan to restore the landmark — known as Halcyon House at 3400 Prospect Street NW — to its original function as a single‑family residence, a spokesperson told The Wall Street Journal. Harris is co-founder of investment firm Apollo Global Management and founder of 26North Partners.

Halcyon House, a Federal‑style estate in Georgetown, dates back to the late 1700s and spans roughly 30,000 square feet. The redbrick mansion includes extensive gardens and a rear pool. The property was not publicly listed, and the transaction occurred quietly off‑market, local agents said.

The seller, Japanese‑born scientist and entrepreneur Sachiko Kuno, bought the home with then‑husband and business partner Dr. Ryuji Ueno for $11 million in 2011. Kuno, who cofounded several pharmaceutical ventures, later repurposed the mansion as headquarters for a nonprofit accelerator.

Harris has deep ties to Washington, having grown up in the capital city and spending significant time there through his ownership of the local NFL franchise. His portfolio also includes ownership stakes in the NBA’s Philadelphia 76ers and the NHL’s New Jersey Devils.

While Halcyon House will be restored as a residence, the couple’s primary home will remain in Miami, where they own a waterfront property on North Bay Road.

The purchase aligns with Harris’s pattern of acquiring and reviving historic real estate. In 2017, he bought New York’s 21,000‑square‑foot Otto Dommerich Mansion for $45 million and converted it back into a single‑family home after years of institutional use.

Built for Benjamin Stoddert, the first U.S. Secretary of the Navy, Halcyon House has been listed on the National Register of Historic Places since 1971. Its Georgetown setting places it among prominent neighbors, including venture capitalist Mark Ein and Treasury Secretary Scott Bessent.

The $28 million sale surpasses the city’s previous record, set in 2024 when Cantor Fitzgerald CEO Howard Lutnick, who currently serves as Secretary of Commerce, bought Bret Baier’s Foxhall estate for $25 million.

Mark and Hunter McFadden of Compass represented the seller Kuno, while Harris was represented by Daniel Heider of TTR Sotheby’s International Realty.
