​This triplex penthouse, located in one of Mayfair’s most prestigious period portered buildings, is generously proportioned, beautifully finished, and situated in one of London’s most iconic locations. The uppermost level is a private roof terrace spanning the entire footprint of the apartment, offering far-reaching views across the city skyline. The ninth floor is entirely dedicated to open-plan living, with sliding glass doors stretching the full width of the apartment. This floor-to-ceiling glazing leads directly onto a deep balcony, creating a seamless indoor-outdoor feel that’s particularly special in the warmer months. The pastel green kitchen is sleek and minimal, with a central island designed for entertaining and casual dining. There’s ample room for a large dining table and a relaxed seating area, all of which look out over rooftops and treetops towards Hyde Park. The bedrooms sit one floor below, accessed via a striking entrance hall with monochrome chequerboard tiling. The principal suite is exceptionally calm, with a walk-through dressing area, a large ensuite bathroom and its own private balcony with the same wide sliding doors. Two further double bedrooms, each with built-in wardrobes, share a beautifully finished family bathroom. A separate powder room lies just off the hallway. Finished throughout in a modern palette of soft greys and clean lines, the apartment also benefits from underfloor heating, air conditioning, and three private balconies. The bathrooms and hallway are clad in marble, while stylish touches from trendy brands like ​L'Objet elevate the interiors. There is 24-hour concierge and security, and the building itself is immaculately kept. Park Lane places you at the heart of Mayfair, moments from Hyde Park and surrounded by some of London’s best dining, shopping and cultural institutions. From the world-class restaurants and boutiques of Mount Street and Bond Street to the historic glamour of private members' clubs and five-star hotels, this pocket of London offers the perfect balance of old-school prestige and contemporary convenience. With easy access to the West End, Knightsbridge and beyond, it’s no surprise this stretch of Mayfair remains one of the most sought-after addresses in the capital.​
