The Mayfair mansion was later owned by French banking heiress Baroness Catherine d’Erlanger.
A London mansion that was once home to poet Lord Byron and banking heiress Baroness Catherine d’Erlanger has hit the market.
Listed for a cool £29.5 million (or roughly $37.7 million), the palatial townhouse at 139 Piccadilly most recently served as an office building. However, the historic property is being sold with full planning permission to convert it back into a single-family house—one that listing brokerage Wetherell estimates would be worth a whopping £70 million (or about $87.9 million).
“The provenance of this Piccadilly mansion building overlooking Green Park is outstanding,” Peter Wetherell, founder and chairman of Wetherell, said in a press statement. “It was once the London home of poet Lord Byron, and during the 1920s and 1930s, it was the Mayfair private palace of French heiress Baroness Catherine d’Erlanger, one of the richest women in Europe at the time. Now a buyer has the opportunity to close the circle and bring this landmark building back to life.”
The Grade II-listed building offers up an impressive 15,339 square feet of living space and still retains tons of period details. Think tall sash windows, ornate ceilings, original fireplaces, and stone staircases.
As a single-family residence, the mansion would include a stately entrance hall, seven grand reception rooms, and eight ensuite bedrooms. There’s also an elevator and a brand-new rooftop garden. Down below, the double basement could accommodate a recreation complex equipped with a movie theater, game room, swimming pool, and a wellness center that sports a sauna, steam room, and gym.
Dating back to the 18th century, the abode was originally built sometime between 1760 and 1764. After it was renovated in 1815, it became the home of the British poet Lord Byron and his wife. According to the listing, Byron wrote Parsinia and The Seige of Corinth in the study of this home. However, he was forced to leave the home in April 1816 after his divorce, which involved an alleged infidelity scandal. The property was later scooped up in 1910 by the Baron and Baroness d’Erlanger.
“This magnificent period building is one of the few surviving private palaces in Mayfair providing a discerning buyer with the opportunity to regenerate and transform it into a single palatial family home, an Embassy, private member’s club, new offices or a flagship retail boutique,” says Robert Britten, sales Director at Wetherell. “Buildings of this scale and importance and in such an ultra-prime Green Park location rarely come up for sale in Mayfair.”
