Private Mansions for sale in Paris

Buying a private mansion in Paris: prime real estate in its rarest form

A private mansion, or hôtel particulier, is a standalone townhouse set over several floors, with no co-ownership. It is the rarest form of prime real estate in Paris. Inherited from the city’s aristocratic and later bourgeois history, these properties are few in number today and rarely change hands.

A private mansion offers a way of living that even a Haussmann apartment cannot. Reception rooms unfold across an entire floor, a grand staircase shapes the house, and the ceiling heights and volumes allow layouts impossible elsewhere. For French and international buyers alike, it means a property steeped in history, a true address and a level of privacy rarely found in conventional real estate.

Private mansion, luxury house or penthouse: what is the difference?

Gardens, courtyards and terraces: the privilege of outdoor space

In a city as dense as Paris, a private garden is one of the factors that weighs most on the value of a private mansion. Not all of them have one. Many have a paved courtyard, a tree-lined patio or terraces open to the rooftops. The most sought-after hide a garden invisible from the street, where summer dinners are held and the noise of the city fades away. For international buyers, this outdoor space often decides between two comparable addresses.

Private roads and gated villas: the search for privacy

Private mansions on private roads, in gated villas or cul-de-sacs are among the most sought-after properties on the Paris market. Access is reserved for residents and their guests, through a gate, access control or on-site staff. Traffic is almost non-existent. Buyers acquire a house, but also a calm and a sense of security that are rare just minutes from the grand avenues.

Villa Montmorency: the most closed address in Paris

Villa Montmorency is a private enclave in Auteuil, in the 16th arrondissement, created in 1853 on the former estate of the Comtesse de Boufflers. Its tree-lined lanes are closed by gates and guarded around the clock: only residents and their guests may enter, after confirmation with the owners. Its founding regulations require houses of at least 150 m² with a proportional garden, which rules out any apartment building.

This discretion has long attracted business leaders, artists and public figures. The private mansions of the Villa offer generous floor areas, private gardens and an almost provincial silence, making it one of the most coveted addresses for buying a private mansion in Paris.

Where to find a private mansion in Paris?

Private mansions are concentrated in a handful of historic areas: the 16th arrondissement, the surroundings of Parc Monceau, the Faubourg Saint-Germain, the Marais and, just outside Paris, Neuilly-sur-Seine.

The 16th arrondissement is the leading market for private mansions in Paris. Around Auteuil, avenue Victor-Hugo and avenue Foch, private roads and secluded villas hold a large share of the supply, much sought after by international buyers. Explore our private mansions and properties for sale in the 16th.

The surroundings of Parc Monceau, between the 8th and 17th arrondissements, gather residences built in the 19th century for the upper bourgeoisie of the Second Empire. On rue Murillo, rue Rembrandt and avenue de Messine, private mansions line the park. On rue de Prony and avenue de Villiers, in the Plaine Monceau, they carry on the same tradition of building. Explore our properties for sale in the 8th arrondissement and in the 17th arrondissement.

The Faubourg Saint-Germain, in the 7th, is home to some of the finest private mansions in Paris, on rue de Varenne and rue de Grenelle. Many now house ministries and embassies, which makes every residential sale all the rarer. Explore our properties for sale in the 7th arrondissement.

The Marais, in the 3rd and 4th arrondissements, keeps some of the oldest private mansions in the city. Around the place des Vosges, some date back to the 17th century. Explore our properties for sale in the Marais.

Neuilly-sur-Seine, on the edge of the 16th, offers a very active market for family houses. The Saint-James area, the surroundings of boulevard Maurice-Barrès and the île de la Jatte account for a large share of it. Explore our properties for sale in Neuilly-sur-Seine.
