A seven-bedroom Freehold mansion on Park Street in Mayfair, formerly the Icelandic Embassy and originally the home of the chairman of Arsenal Football Club, has sold for £22m in what is the area’s most expensive house deal in the first half of 2025.
The 6,949 sq.ft. residence was sold by Clifton Property Partners and Beauchamp Estates to an undisclosed ultra-high-net-worth buyer.
Yahya Swallem, senior sales negotiator at Beauchamp Estates, introduced the buyer and worked in conjunction with Robert Windsor, co-founding director of Clifton Property Partners, who was instructed by the vendor.
Swallem said: “Beauchamp Estates are delighted to have introduced the buyer who wanted a turn-key luxury family home in the heart of Central London in Mayfair, arguably the capital’s premier and most sought after address.
“We worked seamlessly with Clifton Property Partners resulting in this landmark deal, which is the most expensive house sale in Mayfair so far in 2025.”
Windsor added: “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.
“It was a real pleasure dealing with Yahya Swallem on this transaction and we worked closely together to ensure a swift and seamless sale.”
The five-storey property, dating back to 1924-1925, features interiors by Dutch designer Marcel Wanders, a private roof terrace, and exclusive access to Green Street Gardens.
It has a colourful past, having hosted Arsenal footballers in the 1930s and later serving as the Icelandic Embassy during the “Cod Wars” between the UK and Iceland.
