Property Of The Week: Ex-Embassy Mayfair Mansion Sold To Ultra-Wealthy Buyer

Clifton Property Partners have successfully sold, to an ultra-wealthy incognito buyer, a magnificent £22 million 6,949 square foot seven bedroom Freehold mansion on Park Street in Mayfair, formerly the Icelandic Embassy and originally the home of the Chairman of Arsenal Football Club: the trophy deal is the biggest house sale in Mayfair during the first six months of 2025.

The mystery buyer wanted a turn-key, ultra-prime family home, which provided security as well as a good long-term investment in Mayfair, London’s most sought after address.

With a brick façade, tall sash windows and stucco detailing in the classical style of Sir Christopher Wren, the five=storey mansion on Park Street provides substantial accommodation over lower ground, ground and four upper floors. Features include a grand staircase, passenger lift, private roof terrace garden and direct access, exclusive to resident’s only, of the Green Street Gardens.

Fully refurbished and modernised for 21st century Mayfair living, the lavish interiors were designed by award winning Dutch designer Marcel Wanders of Marcel Wanders Studio.

The house provides a spacious entrance hall and four reception rooms over the ground and first floors. The VIP principal bedroom suite, with bedroom, walk-in dressing room and main bathroom has its own private level on the second floor, with four further bedroom suites (three ensuite) on the upper floors. There is a kitchen/breakfast room and two bedrooms on the lower ground floor.

As the Icelandic Embassy the Park Street mansion was at the centre of a diplomatic storm between the UK and Iceland during the 1950s and 1970s, the so-called “Cod Wars”, when Royal Navy and Icelandic Coast Guard ships rammed each other in disputes over fishing rights in Icelandic waters. The dispute was resolved by Prime Minister James Callaghan in 1976 with UK trawlers given access to Icelandic waters.

Robert Windsor, Co-Founding Director of Clifton Property Partners says: “We are delighted to have successfully negotiated the sale of this magnificent Freehold mansion on Park Street which shows the resilience of the Prime Central London market. Impeccably interior designed and dressed by Marcel Wanders Studio, the house was sold “turn-key” which is what most of our buyers seem to be looking for at present. Buyers in Prime Central London want dressed, turn-key homes which can be moved into immediately without the need for modernisation work. This trophy home deal is a text book example of this."
