Occupying the top floors of 100 George Street W1, developed by Native Land, this newly completed four-bedroom duplex penthouse offers an exceptional 5,528 sq ft of combined internal and external living space, including a remarkable 2,398 sq ft landscaped private terrace with panoramic views across London's skyline. Designed as a true house in the sky, the residence combines the scale and privacy of a family home with the convenience of one of Marylebone's most prestigious addresses.

Extending across the fifth and sixth floors, the penthouse spans 3,130 sq ft of beautifully appointed interiors by Cuturi Cameto. The duplex arrangement creates a natural separation between living and sleeping accommodation, providing a sense of space rarely found in Prime Central London apartments. Floor-to-ceiling glazing floods the home with natural light, while bespoke finishes, curated artwork and exceptional craftsmanship feature throughout.

The upper level is dedicated to entertaining, with a spectacular formal reception and dining room, alongside an informal family living area centred around a bespoke Bulthaup kitchen. Finished with silver travertine surfaces and premium Miele and Sub-Zero appliances, the space has been designed for both everyday living and large-scale entertaining.

Accommodation comprises four generous bedrooms, including an impressive principal suite with dressing area and luxurious natural stone bathroom. The fourth bedroom currently functions as a beautifully designed study, offering flexibility for family life, guests or home working.

Crowning the residence is an extraordinary private roof terrace by Cameron Gardens. At nearly 2,400 sq ft, it is one of the largest private terraces in Marylebone and larger than many three and four-bedroom London apartments. Thoughtfully landscaped with distinct areas for dining, entertaining and relaxation, it has been conceived as a true extension of the home, creating an exceptional outdoor living experience rarely found in central London.
