A French private buyer acquired the 1,325 m² residence of the Moroccan royal family in July 2026, according to Engel & Völkers. In the Maurice-Barrès–Les Sablons neighborhood, this mansion in Neuilly-sur-Seine is set for major renovations. Its price remains confidential. The sale underscores the importance of location in luxury real estate Neuilly-sur-Seine. Notaries, however, describe a regional market that is still fragile.
A Summer Sale Made Public In September
The announcement was released on September 17 in a press release signed by Engel & Völkers France. The real estate network says it handled the transaction, without specifying the date it was signed. The event therefore dates back to the summer, even if the media coverage continued into the fall.
The agency’s description conveys the scale of the property. It has 16 main rooms, a 245 m² landscaped garden, and a 105 m² rooftop terrace. It notably includes eight suites, a swimming pool, a hammam, and a fitness room. The residence also offers, according to the broker, open views of the Bois de Boulogne and Fondation Louis Vuitton.
These features describe a residence intended for a single family. The term mansion does not refer here to a hotel. Despite its amenities, the house will require major work, which the new owner plans to undertake. The agency therefore does not present this sale as that of a fully renovated property.
In Neuilly-Sur-Seine, The View Before The Building Condition
Sandra Sabah heads the Engel & Völkers Paris 17th North and Hauts-de-Seine office. She explains the buyer’s choice by the home’s surroundings. In her view, the outlook onto the Bois and the lack of overlooking neighbors mattered more than the living space alone. Renovation can change the interior layout; it cannot give another building the same setting.
The professional believes a family residence of this kind comes on the Neuilly market only about once a decade. She links this rarity to limited land turnover and the splitting up of many large houses into apartments. This assessment comes from the agency that sold the property: its press release provides no tally to measure how often it happens.
The agency also observes, among some of its wealthy French clients, a greater willingness to take on major renovations. It contrasts that choice with the search for move-in-ready homes. This deal illustrates that tradeoff, but it does not by itself measure changing preferences among all buyers in western Paris.
The Asking Price Does Not Reveal The Final Price
In a September 20 article, Le Figaro reports a range of €17 million to €18 million, according to its own information. The newspaper notes that the residence was listed at €20 million. This estimate of the negotiated amount is not confirmed by Engel & Völkers, which keeps the sale price confidential.
A distinction must therefore be made between the asking price, the amount mentioned by the newspaper, and the figure recorded in the deed of sale. Only the latter would make it possible to calculate the purchase precisely. The renovation budget has not been disclosed either. The total cost of the project therefore remains unknown.
The buyer’s identity has not been made public. The agency’s announcement also does not specify the selling legal entity or the reasons for the transfer. That ownership does not allow the decision or the proceeds of the sale to be attributed solely to Mohammed VI.
Notaries Describe A Recovery That Is Still Fragile
At another scale, data from the Notaires du Grand Paris temper the idea of a uniformly dynamic real estate market. Their second-quarter 2026 report, published on September 8, records 31,750 sales of existing homes in the Île-de-France region. These transactions were completed between April and June. That is 10% more than a year earlier.
Part of that rebound, however, reflects the weak comparison point. At the start of 2025, some purchases had been brought forward to get ahead of the increase in transfer taxes, the taxes collected when a property is sold. The following quarter was less active. For the first half of 2026, year-over-year growth reached 4% for apartments and 7% for houses.
Regional prices, meanwhile, are changing little. Over one year, notaries recorded a 0.3% decline for all existing homes. Apartments gained 0.3%, while houses fell 1.5%. Their assessment points to an improvement in activity that remains uneven.
These figures cover the Île-de-France region as a whole and do not specifically describe mansions in Neuilly. They provide context for the transaction, without confirming a rebound specific to multi-million-euro homes. The view that demand above €5 million remains strong is still Engel & Völkers’ own.
A Singular Address Cannot Be Reduced To An Average
The notaries’ price map distinguishes apartments from houses and relies on transactions from the past three months. Its so-called standardized prices adjust for differences in the characteristics of sold properties, in order to better track market trends. These are statistical markers, not individual appraisals.
Applying a municipal average to this 1,325 m² residence would overlook its garden, its view, its family use, and the necessary work. Without a signed price or a publicly disclosed construction cost, the respective weight of these elements in the negotiation cannot be isolated. The sale documents a buyer’s choice for a specific location. It does not yet give the property’s value once renovated.
