Aspiration and ultra-prime London living are available in large doses at the duplex five-bedroom penthouse The Astor in the heart of London’s political seat, Millbank.
This is a rare chance for property investors to own a slice of history and one of London’s most prestigious addresses backed by the weight of heritage and a premier postcode at 9 Millbank.

Five-bedroom heritage duplex The Conrad with riverfront terrace and iconic views of the Thames and Parliament
Meeting the most exacting of London lifestyle aspirations of the world’s ultra elite is this powerful punch of a large format duplex penthouse, which combines the weight of history with ultra modern standards of extravagance and staggering opulence.
The Conrad crowns an iconic 1920s Grade II-listed building, which lines the bank of the Thames in the heart of Westminster in the seat of British politics.
It’s the trophy, turnkey residence sitting at the crest of a sensitive conservation and ultra-prime redevelopment of a former office building into 189 of some of the world’s most coveted apartments.
The jewel in the crown is the building’s super prime Heritage Collection, which includes five manor-style homes on the top floors – once housing ICI directors’ offices – and a named after iconic British figures: politician Nancy Astor, novelist Joseph Conrad, artist Thomas Gainsborough, army officer Fitzroy Somerset and author Horace Walpole.
Although only recently installed and completed in 2023, the residences aim to give the impression that they have organically always served as residential spaces.
Spanning an impressive 7, 219 sq ft high ceilings and large windows of the original 1920s structure form the handsome bones of this large-format home.
Other sensitively restored period features include decorative plasterwork, ceiling cornances and wooden panelling.
At the centrepiece in the vast double-height living room is a gold, sculptural spiral staircase which connects the two floors. On the lower floor is the living area, kitchen and spectacular dining room, while the upper floor offers a more relaxed living area and staff quarters.
An added quirk befitting an old building that’s full of state secrets is the members’ club-style bar hidden away in the eaves of the building. This area was only discovered when construction began.
Although internally The Conrad is a bona fide showstopper, it is perhaps the penthouse’s external space that flanks the apartment that does most of the talking behind the scenes. A river-fronting terrace spills onto cinematic, money can’t buy views of the Thames and the Houses of Parliament.
Residents at 9 Millbank have access to Littlefair-designed amenity spaces, including the gym, pool, spa, cinema room, meeting rooms, underground parking and a 24-hour concierge.
