A Marylebone penthouse with Cuturi Cameto interiors and an expansive private roof terrace

The sixth floor is devoted to living and entertaining, with separate spaces for formal gatherings and everyday family life. Extending to approximately 28 ft., the reception and dining room has broad windows, timber flooring and bespoke joinery incorporating a concealed bar. An Arts and Crafts-inspired fireplace, finished with handmade tiles by Adam Ross, forms a focal point beneath a mural by Andrew Viner.

Across the hall, the kitchen opens onto a family room, with a banquette dining area providing a comfortable setting for informal meals. Bulthaup cabinetry is paired with silver travertine worktops and an island with breakfast seating, complemented by Miele and Sub-Zero appliances and a Zip tap. A separate utility room and guest cloakroom complete this floor.

The bedrooms are arranged on the fifth floor, keeping the sleeping accommodation separate from the principal entertaining spaces. The main suite includes a dressing room and an ensuite bathroom with a bath, separate shower and twin basins. Two further bedrooms have their own ensuite bathrooms, while a fourth bedroom, currently arranged as a study, is served by a separate shower room. Walnut joinery and bronze-green grasscloth give the study a distinctive character, with space for a bespoke desk and shelving.

Above, the private roof terrace has landscaping by Cameron and open views across the surrounding rooftops. Generous areas for seating and planting are complemented by a large pergola with electric blinds, creating a sheltered space for outdoor dining.

Lift access serves both accommodation floors, while underfloor heating and comfort cooling run throughout the principal rooms. Residents also benefit from a concierge, dedicated management team and 24-hour security. Shared facilities include a library with a coffee bar, a residents’ lounge suitable for private screenings, a meeting room, and a fitness studio with a sauna and treatment room. Secure underground parking and additional storage are available by separate negotiation.

Within the Portman Estate, 100 George Street is well placed for Marylebone’s independent shops, restaurants and galleries, including the Wallace Collection. Residents have direct access to Loxton Walk’s landscaped courtyard, with Mayfair, Hyde Park and Regent’s Park also within easy reach.
