Set behind imposing gates on The Bishops Avenue, often referred to as Billionaires’ Row, the incredible five-bedroom penthouse at Hampstead’s Buxmead development unfolds across 9,677 square feet – providing ample space for former tenant Ariana Grande. Nicknamed by some as London’s residential Fort Knox, the exquisite home is set within 2.5 acres of landscaped garden, supported by a on site security team.
Designed by Harrison Varma, one of the capital’s most prestigious luxury developers, the penthouse offers an expertly managed and highly secure space for those requiring the utmost in privacy, discretion, and luxury.
Interiors have been conceived by the award-winning SHH Architecture & Interior Design with a focus on bringing the beauty of the outside in, mirroring the leafy Hampstead views from the 360-degree wraparound terrace, which extends to almost every room. Using a palette of soft, subtle greens, warm earthy tones and rich sumptuous timbers, the effect creates a tranquil, grounded and elegant ambience, in keeping with its bucolic position and secluded treehouse feel.
The main living level of the penthouse comprises a bedroom wing and a vast reception room, which opens onto the wraparound terrace with uninterrupted vistas stretching towards Kenwood House and Hampstead Heath, delivering an epic feel of scale, depth and flow. A private lift connects to a lower level with a private dining room, study, bar, cinema and games room, alongside a gym and additional kitchen.
One of the most impressive features of the penthouse is the practical six-car private garage, directly accessed via the lift. With a focus on discretion, the homeowner would be able to arrive and depart unseen, ideal for high-profile residents and their guests.

Beyond the beautiful penthouse itself, residents have access to more than 15,000 square feet of amenities, including a sprawling 25-metre indoor pool, Technogym fitness centre, spa with treatment rooms, sauna, steam room, hammam and Jacuzzi, alongside an 18-seat cinema, private games room and a residents’ lounge. There is also a business centre, concierge, daily housekeeping and dedicated wellness services.
Positioned between Hampstead and Highgate, The Bishops Avenue offers an exceptional balance of tranquility and connectivity, with village life, independent boutiques, cafés and restaurants all close by, alongside some of London’s most prestigious schools and the sprawling expanses of Hampstead Heath and Kenwood House.
Alexander Main, founder of sales agent Alexander Main, says: “I genuinely believe the penthouse at Buxmead is a rare piece of real estate and, in my view, the best penthouse currently available in North West London. It is completely private and secluded from the outside world and enjoys direct views of Kenwood and Hampstead Heath from the extensive wraparound terrace. The finishes and attention to detail throughout are unrivalled – not only with regards to the décor, but also the layout and floorspace.”

Becky Fatemi, executive partner at United Kingdom Sotheby’s International Realty, says: “This is a penthouse that understands exactly what today’s ultra-prime buyer is looking for. It’s not just about scale, although the volume here is exceptional, it’s about how that space is used. Everything flows, everything feels considered, and there is a real sense of calm from the moment you step inside.
“What really defines Buxmead is its reputation for a level of security and discretion that is incredibly difficult to replicate. It attracts global individuals who want to live well without being seen, and that is reflected in every detail of the development. You also have these incredible green views towards the Heath and Kenwood, which completely change the feel of the apartment. It doesn’t feel like central London living, it feels far more open and relaxed, which is incredibly rare at this level. For a buyer looking for something turnkey, lateral and fully serviced, with genuine substance behind it, this is one of the strongest offerings currently available in North-West London.”
