Crowning the building, the duplex penthouse at One Casson Square offer a lifestyle defined by elegance. Full-height windows and thoughtfully oriented spaces provide sweeping city views.

Description
One Casson Square stands as a bold architectural statement in stone, glass, and bronze—an instant landmark that feels rooted in its surroundings. Designed by Michael Squire of Squire & Partners, the building balances centrality with calm, offering a refined urban retreat.

Inside, full-height windows and carefully oriented spaces frame panoramic views that evolve with the seasons. Interiors by Johnson Naylor elevate everyday living, with soft curves, seamless transitions, and thoughtful details—from hardwood floors and pocket doors to a sculptural staircase and view-focused layouts.

The Penthouse is a masterclass in purposeful design. The kitchen, warm and sociable, features quartz and marble surfaces, custom oak cabinetry, and integrated Gaggenau appliances. Bespoke furnishings and curated lighting add character, while floor-to-ceiling windows keep the city in constant view.

The dining area is dramatically positioned to overlook St Paul’s Cathedral, the Financial District, and Westminster. A Calacatta Viola marble table, rust-toned leather chairs, and a commissioned artwork from the Far East create a space rich in texture, tone, and conversation.

Location
Situated at the heart of London’s vibrant Southbank—opposite Westminster and the Houses of Parliament—One Casson Square enjoys one of the city’s most connected and iconic locations. Set within Southbank Place, it offers a rare vantage point: Immersed in the capital yet elevated above it. Unlike its North Bank counterparts, it provides a unique perspective, with London’s most treasured landmarks just steps away.

Outside your door are the London Eye, Royal Festival Hall, and Southbank Centre, with the National Theatre and The Old Vic moments away. A short stroll across Hungerford Bridge leads to Covent Garden and Leicester Square, while the ever-present silhouettes of Big Ben and the Houses of Parliament anchor the skyline.

This location is not only inspiring but exceptionally convenient, with Waterloo Station offering seamless access via National Rail and the Jubilee Line. Designed to blend heritage with forward-thinking living, the Penthouse at One Casson Square embodies a constant dialogue with its surroundings—where timeless views meet modern life.
