Home of Artemis Onassis is being brought to market

All Square


An Ambassadorial 1st floor apartment at 47 Grosvenor Square providing 5,006 square feet of lateral living space with a 63 foot balcony and south facing terrace, formerly the London home of Artemis Onassis, sister of billionaire Aristotle, is the finest residence and refurbishment opportunity in the world-renowned square and is being brought to market by sole agent Wetherell for the first time in 28 years.

One of the largest and grandest apartments in Grosvenor Square, the 1st floor five bedroom apartment at 47 Grosvenor Square has an illustrious history which combines aristocracy, wealth, glamour and celebrity.

The palatial brick and stone apartment building was built in 1938-1939 in a neo-Georgian style to designs by Detmar Blow, Estates Manager to the Duke of Westminster, and Fenand Billerey, the  French Beaux-Arts architect. The internal fit out was disrupted by WWII so it was not until after 1945 that the building was fully completed, allowing residents to occupy the apartments.

The only apartment in the building with a balcony overlooking Grosvenor Square, the 1st floor apartment spans the prime central frontage, and extends the entire width and depth of the building, benefitting from a spacious south facing private terrace overlooking the rear façade.

The residence has three adjacent reception rooms, totalling 63 feet in length, all facing the square, complete with an impressive entrance hall, family kitchen, library, bar, guest powder room, five bedrooms, four en-suite bathrooms, guest bathroom, utility room and walk-in storage room.

Benefitting from a bright and airy ambience, the apartment has grand spacious rooms, floor-to-ceiling windows providing unparalleled views across Grosvenor Square and generous ceiling heights of 10.3 feet.

The large reception hall gives access to the 32 foot main reception room, formal dining room and study, all opening onto the ornamental balcony overlooking Grosvenor Square. This trio provides approximately 2,000 square feet of reception space facing over the gardens of Grosvenor Square.

The library has full height glazing, with sliding doors opening onto the private terrace overlooking the south facing rear façade of the apartment building. The large family kitchen and breakfast room has a central island with breakfast bar, complete with a separate cocktail bar and utility room.

The size of a conventional apartment, the magnificent master bedroom suite has large His and Her walk-in dressing rooms and His and Her master bathrooms. There is also a principal guest suite with walk-in dressing room and en-suite bathroom. There are three further bedrooms, one with an en-suite and the others sharing a guest bathroom. The apartment building has a grand ground floor entrance foyer with two passenger lifts and 24 hour uniformed porterage.

Peter Wetherell, Chief Executive of Wetherell says: “With its iconic address, balcony and terrace and garden square views this expansive Mayfair residence at 47 Grosvenor Square is the finest apartment in Grosvenor Square. This is a trophy property, which would serve as an excellent long-term investment and main London residence. The apartment would benefit from a refurbishment to provide the latest specification and interior dressing but such a makeover could add an additional £1,000 per square foot to the value of the property. Once dominated by diplomatic buildings, Grosvenor Square is currently being returned to its residential origins, with buildings being converted into luxury apartments and new hotels, this transformation will make the square the best residential address in central London.”

Wetherell highlight that Grosvenor Square is currently benefitting from a luxury makeover. The former Canadian Embassy and US Naval Building are being transformed back into luxury apartment buildings and the former US Embassy is set to become a 5-star Rosewood Hotel with cafes and luxury boutiques.

The central garden square is also set to be transformed with a new landscaping scheme and enhanced public realm, with the formerly closed area in front of the US Embassy being transformed into a magnificent public piazza fronting onto the new Rosewood Hotel.

Peter Wetherell says: “Grosvenor Square is seeing its biggest transformation in a century. The buildings around the square are either returning to their residential origins or being transformed into new luxury hotels, this major step change which will help to enhance residential capital values in the square and add to the desirability of this already highly coveted world-renowned address. Given this wider context, the apartment at 47 Grosvenor Square has the potential to become one of the finest residences in central London.”

The 1st floor apartment at 47 Grosvenor Square is for sale for offers in the region of £25,000,000 (999 year lease/share of freehold). Viewing is strictly by appointment, contact sole agent Wetherell on 020 7529 5566 or visit www.wetherell.co.uk
