If you peer through the leafy canopies of Green Park, you’ll spy a grand mansion proudly standing watch. From its Piccadilly vantage point, Cambridge House has welcomed some of the capital’s grandest residents across its threshold, from Queen Victoria and Lawrence of Arabia to author Ian Fleming. For more than two decades, it was home to Prince Adolphus, Duke of Cambridge, then became the townhouse residence of Prime Minister Lord Palmerston, before finally acting as a base for the Naval and Military Club (otherwise infamously known as the In & Out Club). Now, this 18th-century landmark is entering its newest lease of life – this time, as a magnificent, marble-draped hotel.

Cambridge House, Auberge Collection sits on Piccadilly, overlooking Green Park

Condé Nast Traveller has the exclusive first glimpse inside the Cambridge House, Auberge Collection, and we can confirm it’s as glamorous as you’d expect. Think marble-veined hallways, Palladian-style courtyards, majestic sweeping staircases and gilded suites, complete with views across Piccadilly and sprawling Green Park beyond. Fresh off the back of their work on The Twenty Two, Burlington Arcade and Admiralty Arch, British businessmen and hoteliers the Reuben Brothers have embarked on a $1.3 billion regeneration project for this area of Mayfair, turning this Georgian mansion into one of London’s glitziest hotels – Auberge Collection’s debut hotel in London.
