Crafted in stone, glass and bronze, the building offers a calm yet commanding presence within this iconic riverside setting.<br/><br/>Spanning 3,692 sq ft, the residence is defined by volume, light and purposeful design.

Two generous reception rooms are designed for both refined entertaining and relaxed living, each orientated to maximise the skyline backdrop.<br/><br/>The kitchen is warm and sociable, featuring quartz and marble surfaces, bespoke oak cabinetry and integrated Gaggenau appliances.

Perfectly positioned moments from the Thames Path, cultural landmarks and Waterloo Station, this is a rare opportunity to own a private sanctuary within one of London’s most celebrated destinations.<br/><br/><b>Location</b><br/><br/>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.<br/><br/>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.<br/><br/>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.<br/><br/>Square Footage: 3,692 sq ft<br/> Leasehold with approximately 998 years remaining.<br/> <br/><br/><b>Additional Info</b><br/><br/>Service Charge - £12.81 pa psf
