Occupying the 35th floor of One Casson Square, showcasing unrivalled views of the Houses of Parliament, the London Eye, River Thames and across to the City of London and The Shard, is the Portia Fox Penthouse at One Casson Square, a magnificent three-bedroom apartment that stretches across two floors. Just released onto the market for £12.95 million, the 3,100 sq. ft. penthouse has been designed and dressed by the award-winning studio Portia Fox.

A collection of bespoke details and artworks have been specially selected to bring the penthouse to life, injecting the interiors with a creative cosmopolitan flair and the ‘quiet luxury’ of a trendy New-York high rise residence.

The spirit of London’s South Bank and its unforgettable views served as inspiration for the overall interior and style of the Portia Fox Penthouse. Calm neutral tones, refined textures, timber panelling and brass accents flow from room to room, providing an equal balance of comfort and sophistication, filling the space with subtle elegance and style without diverting attention from the 360º views across London.

Portia Fox has managed to seamlessly blend these breath-taking views, taken in through triple glazed floor to ceiling windows that also fill each space with natural light, with the interior scheme, ensuring minimalist and discreet details mirror the poised nature of the London landscape, creating an atmosphere that reflects the serenity of the city skyline from sunrise to sunset.

Portia Fox, the Founder and Creative Director at Portia Fox, commented: “I am thrilled to be launching this project and delighted that we have been able to successfully execute the classic and timeless vision that we had in mind from the initial concept for this impressive penthouse. By capitalising on the extraordinary views across the London skyline, which takes in every recognisable landmark, as our main source of inspiration, we have cultivated a space that consistently compliments its surroundings.

“Here, the owner can still appreciate scenes of the urban bustle outside the apartment whilst also enjoying being above it all. The penthouse has a unique feel that is part New York high rise sophistication and part a hub of culture and creativity that so defines this stretch of the South Bank.”

Whilst working alongside a collection of expert furniture makers, artisans and artists, 80% of which are based nearby or in the UK, the Portia Fox studio has strived to integrate a series of custom-made furnishings across the apartment, all of which are purpose built to perfectly complement the unique footprint of the penthouse.

These one-of-a-kind artworks support the penthouse’s status as a truly exclusive residence, with bespoke features that cannot be found anywhere else – such as the bedside tables in the master bedroom, manufactured by the Treeslounge workshop, who have worked in collaboration with many of the UK’s leading interior design and architectural practices.

Other standout artisan pieces include the artful and plush rugs found throughout the apartment, made by London-based atelier Holland Cassidy, who pride themselves upon engaging in entirely ethical practices while creating their high-end products. Lastly, there is also a statement dining table and console table from specialist furniture makers Novocastrian, which were handcrafted in the North of England, harnessing the honest beauty of raw and natural materials.

Adding a unique touch and a real sense of sustainable luxury to the penthouse Timber from fallen trees in London have been used by sustainable design house Process Studio to create a set of pippy oak bedside tables in the guest bedroom.

Discussing the penthouse launch, Richard Oakes, Chief Sales & Marketing Officer at Qatari Diar, said: “Due to its position, size and the views on offer, the Portia Fox Penthouse is certainly one of London’s most exclusive residences. We needed to ensure the home was presented to its full potential and knew Portia Fox would deliver an interior design that further enhanced the penthouse’s exclusivity.

“The final design is captivating and perfectly complements the layout and breath-taking views on offer. The interiors have a warm and welcoming feel yet still bring a sense of excitement, so we’re confident that potential purchasers will easily imagine themselves living at this statement address.”

Melanie Conway, Director of Residential Sales at Canary Wharf Group, commented: “The Portia Fox Penthouse is a special apartment that will captivate potential purchasers with a design that is a reflection of the South Bank and the modern lifestyle at this level. The views on offer are unparalleled and the penthouse offers the rare quality of presenting these stunning vistas from every side. We’ve been sure to wait until the apartment was ready until we released it onto the market and are excited to show it to a growing collection of would-be purchasers.”
