Côte d’Azur Sotheby’s International Realty unveils an iconic penthouse, a unique legacy of Nice’s history

Côte d’Azur Sotheby’s International Realty is privileged to announce the exclusive listing of an exceptional property, ideally located in the heart of Nice’s prestigious Carré d’Or, just moments from the legendary Hôtel Negresco.

Occupying the entire top floor of the Palais Alphonse XIII, this penthouse represents a rare piece of Nice’s architectural heritage. Designed from the outset during the building’s construction in 1927, it is not a later addition but a residence conceived as a singular crowning achievement, an exceptionally uncommon vision for its time. Having remained undivided since its completion, it preserves the full integrity and original intent of its commissioner.

An exceptional architectural and historical legacy

The Palais Alphonse XIII stands as one of Nice’s most significant interwar developments. Commissioned by Josep Torres i Jonama, a Catalan industrialist and philanthropist who built his fortune between Europe and the United States, the building reflects both technical innovation and aesthetic ambition.

Entrusted to Nice-based architect Albert Galli, the project is distinguished by its use of reinforced concrete, a pioneering technology at the time, discreetly concealed behind an ornate neo-classical façade. Decorative mascarons, shells and cornucopia motifs enrich an exterior inspired by Belle Époque codes, deliberately diverging from the prevailing Art Deco style of the period.

At a time when upper floors were traditionally reserved for staff, the creation of a penthouse occupying the entire summit of the building embodied a distinctly modern vision, foreshadowing a new way of living on the French Riviera, oriented towards light, views and expansive outdoor spaces.

A lifestyle between sky and sea

Offering over 715 sqm of private space, including approximately 280 sqm of living area, the apartment delivers a residential experience comparable to that of a villa suspended above the city.

Invisible from the street and enjoying absolute privacy, it opens onto an extraordinary 435 sqm terrace, a true rooftop garden with breathtaking views over the sea, the Negresco, the city and the surrounding hills. This outdoor space, exceptionally rare at such scale in central Nice, features refined landscaping, including reception areas, a summer kitchen, relaxation zones and Mediterranean plantings.

The interiors, fully redesigned to meet contemporary standards, feature generous reception rooms, an elegant dining room, a high-quality family kitchen with dedicated service areas, as well as a wine cellar. The night area comprises five en suite bedrooms, complemented by an independent staff suite.

The property showcases a high level of craftsmanship, combining noble materials, artisanal expertise and bespoke finishes throughout.

A home lived in and passed on

The current owner, a French businessman active in the medical and real estate sectors, has developed a deep personal connection to the property. Shared with his two children and six grandchildren, it has been the setting for many family moments, shaping it into a true home as much as a heritage asset.

This human dimension further enhances the already exceptional value of the property, which stands out as much for its history as for the emotion it inspires.

A rare opportunity on the international market

With its unique volumes, nearly century-old integrity, iconic location and outstanding amenities, this penthouse represents an exceptionally rare opportunity on the French Riviera real estate market.

Ideally located close to the beaches, the most prestigious establishments and Nice’s iconic addresses, it is perfectly suited to an international clientele seeking a truly distinctive property combining heritage, privacy and refined living.
