Everything about The Rossetti speaks to extraordinary and elevated living—from its literary namesake to its sought-after location, thoughtfully curated interiors, and the books on its shelves. This luxury penthouse spans 3,600 square feet with three bedrooms, three baths, and a sweeping 1,400-square-foot wraparound terrace overlooking London’s rooftops.
The penthouse’s name refers to Christina Rossetti, the Victorian poet who called this historic and colorful West End neighborhood home. Today, the area is a much-desired urban village with a rich cultural heritage, beloved for its independent shops and cafés, traditional pubs, and chic boutiques, all wrapped in a tranquil yet sophisticated ambience.

The interior architecture is the work of Simon Bowden of E8 Architecture, formerly of Foster + Partners. Bowden’s design philosophy centers on flexible, open-plan living that appears deceptively simple while maximizing natural light. Classic materials anchor the space: Oak flooring, Italian marble, and natural stone create a contemporary and elegant feel. The interior design by Phil Waterson of Waterson Consultancy overlays the light-filled space with a sense of drama. The journey begins upon entering The Rossetti, where the deep gray lobby, framed by Crittall glass doors, opens onto an enfilade of rooms bathed in natural light. Floor-to-ceiling windows front the penthouse, framing views of the rooftop garden and London’s skyline beyond.
The generous proportions of the rooms complement the invitingly sculptural B&B Italia furniture (included with the penthouse) and a carefully selected collection of contemporary pieces. In the living area, a crescent-shaped sofa is illuminated by a 1930s Art Deco ceiling lamp. Centering the entertainment area is a Welsh black slate bioethanol fireplace, while in the dining room, where custom cabinetry lines the walls, a modern Venetian chandelier hangs from a dark industrial steel frame.

The private areas of the home are equally exquisitely furnished, featuring stunning contemporary works of art, softening drapes, and thoughtfully curated books and accessories. Notes Waterson, “I explored the fantastic shops in Marylebone village to accessorize the penthouse. I wanted to imbue The Rossetti with the feel of the neighborhood and continue that sense of location and community by working with local shops and services.”
E8 architects collaborated with Italian design firm Salvatori, who appointed the sleek and sumptuous bathrooms with Gris du Marais marble in its dappled gray-brown pattern.

The 1,400-square-foot wraparound terrace subtly divides into a series of distinct “rooms,” creating a seamless indoor-outdoor living experience. The interior’s curved picture windows, balusters, and organic forms are mirrored outside in the ribbon-like planters of staggered height that both add dynamism to the terrace landscaping and also preserve privacy. Says Waterson, “I wanted the greenery of the terrace garden to become an intrinsic part of the interior experience.” He worked with landscape architect Joe Brimson, who planted specimen trees, contrasting foliage forms and textures, perennial grasses, and white-flowering shrubs and perennials that bloom throughout the year. The result is a jaw-dropping sky garden—a spectacular sight from inside the home and a serene sanctuary when you’re outside.
The Rossetti is one of seven available penthouses in Marylebone Square, a new mixed-use landmark building developed by Concord London. Marylebone Square reimagines traditional mews living through contemporary design, set around a stunning five-story courtyard with an expansive glass roof and open sides.
The Rossetti includes two private EV parking spaces, 24-hour concierge service, and a rare 999-year lease. It is offered at £27 million.
