In a city where privacy is prized and space is increasingly scarce, London penthouses have become the ultimate status purchase for high-net-worth buyers. These top-floor homes appeal not only for their skyline views and expansive terraces, but for the lifestyle they offer, with concierge-led living, hotel-level wellness facilities and a sense of total escape above the streets below.
Buyers continue to compete for best-in-class apartments in addresses such as Knightsbridge and Mayfair and recent market data has pointed to a broader mix of buyers entering the top end, noting a rising share of under-40s purchasing in London’s £10m+ market. There is also an unusually wide choice of super-prime new-build stock across prime central sub-markets, reinforcing how competition is increasingly about which building offers the best lifestyle and long-term value, rather than simply buying into a postcode.
In this guide, we take a closer look at the best penthouses in London.

Clarges, Mayfair
Clarges Mayfair is a boutique development of just 34 residences across ten floors and offers a rare collection of one- to five-bedroom apartments designed to sit among Mayfair’s grand historic neighbours. Inside, each home is finished with an emphasis on craftsmanship and understated luxury, from warm, calming colour palettes to carefully curated art, furniture and fittings.
Crowning the building is a penthouse arranged over three floors, spanning 7,868 sq ft with an additional 2,775 sq ft of outdoor terrace space, created for family living and large-scale entertaining. Two ninth-floor reception rooms connect via sliding doors and sit alongside a sleek eat-in kitchen featuring a marble island and minimalist cabinetry, while floor-to-ceiling glazing draws in the skyline beyond. The wraparound terrace delivers sweeping 360-degree views across Mayfair, Green Park and London’s most recognisable landmarks.
Below, the eighth floor houses six generous en-suite bedrooms, including a principal suite with a dramatic marble bathroom reached through a walk-through wardrobe, plus further terraces, an additional reception room and practical back-of-house spaces. Above, a tenth-floor roof terrace provides another exceptional location for summer hosting, with elevated views over the park and the city. A sculptural staircase unites the three levels, while residents of Clarges benefit from discreet five-star amenities including a secure drop-off, private spa, 25-metre pool, gym, sauna, steam and treatment rooms and a private cinema, alongside two underground parking spaces and a location moments from Green Park, Bond Street and Mayfair.
Set across the second and third floors of Grade II-listed building Gatti House, this elegant pied-à-terre forms part of one of the most notable buildings on the Strand. Located between Fleet Street and Trafalgar Square, the building takes its name from the Gatti family, whose influence shaped much of the area’s historic commercial and cultural life, including the Adelphi Theatre.
The apartment has been carefully restored to retain much of the building’s character, with many of the original features existing alongside contemporary touches, such as air conditioning and rich oak flooring throughout.
The main living space is reached by a timber staircase, with French doors that lead into an open-plan room, defined by rustic, exposed beams and overhead skylights. The layout accommodates a fully integrated kitchen alongside separate dining and seating areas, with a further balcony extending the living space externally. Bedroom accommodation is arranged across the lower level and each suite includes fitted wardrobes and magnificent bathrooms, each finished in deep and vibrant hues.
Charles Street, Mayfair
Set over the fourth and fifth floors of an exclusive new Mayfair development by REDD, this impeccably finished duplex apartment delivers a mix of period character and contemporary design, located moments from Berkeley Square. Created in collaboration with renowned design studio 1508 London, the interiors pay tribute to the building’s heritage through traditional plaster mouldings and cornicings, Havwoods European oak herringbone flooring and bespoke joinery throughout.
The fourth floor is dedicated to entertaining, where soaring ceilings, oak parquet floors and a trio of arched floor-to-ceiling windows with French doors fill the open-plan reception and dining space with light and open directly onto a private terrace. A bespoke dine-in kitchen sits alongside, finished with marble worktops and splashbacks, premium Gaggenau and Miele appliances, a large wine fridge and sleek Dornbracht tapware. Upstairs, three generous en-suite double bedrooms offer calm and privacy, led by a principal suite with a spa-like bathroom and a walk-through wardrobe fitted with custom cabinetry, while the remaining bedrooms each feature en-suite shower rooms and built-in storage.
Security and service are important features of the development, with Banham locks, video entry, lift access and a 24/7 concierge service. The address sits at the heart of Mayfair and is steadily emerging as one of the area’s most anticipated new launches, already achieving record-setting sales during its off-market period.
The Bishops Avenue, Hampstead
Set on top of the highly exclusive Allingham Court on Bishop’s Avenue, this exceptional 6,015 sq ft penthouse is one of just 12 apartments, offering four bedrooms, expansive outdoor space and a superb suite of resident facilities. The home centres around two grand reception rooms and a spacious dining hall, all flooded with natural light and finished to an exacting standard, with a sweeping terrace providing an elegant extension of the living space and views across the neighbourhood.

Residents of the development enjoy landscaped communal gardens, a gym, sauna and swimming pool, alongside ample covered parking, lift access, four private parking spaces, storage and a 24-hour concierge. The apartment is well placed for access to green space and the appeal of nearby Kenwood House, as well as the restaurants and boutiques of the surrounding area, with East Finchley Underground Station just half a mile away.
