In brief
- A 1,325 sq m private mansion that belonged to the Moroccan royal family was sold in July 2026 to a buyer of French nationality.
- The residence notably includes 16 main rooms, eight suites, a wellness area with a swimming pool, and a 105 sq m roof terrace overlooking the Bois de Boulogne.
- In the first half of 2026, the average price in Neuilly-sur-Seine stood at €10,800/sq m, demonstrating great resilience in the ultra-luxury market.
However, this overall average conceals deep disparities in valuation depending on the neighbourhoods of the municipality. The most sought-after sectors, particularly those directly bordering the green edges or offering exceptional architectural configurations, completely break free from standard price grids. This overall resilience demonstrates the municipality’s strong appeal to wealthy families and leading investors, who perceive the land in this residential enclave as one of the most secure in the Île-de-France region.
In the highly exclusive world of luxury real estate in Neuilly-sur-Seine, a private French buyer acquired a 1,325 sq m architectural property in July 2026 that had belonged to the Moroccan royal family. Negotiated through the high-end real estate house, this major transaction, the final amount of which remains strictly confidential, reflects the renewed vitality of very large properties in the west of Paris. Between a courtyard of honour, suspended terraces, and private wellness areas, this residence illustrates the unwavering appeal of heritage addresses to high-net-worth individuals.
The identity of the buyer, a French citizen whose business and background remain discreet, confirms the strong comeback of domestic wealth in the exceptional property market. While previous decades had been marked by a strong dominance of international capital in the ultra-luxury segment, the year 2026 establishes the sovereignty of local buyers. The latter are primarily looking for family properties capable of spanning generations, combining the functionality of a first-rate primary residence with the safe-haven value of an extraordinary real estate asset.
An extraordinary architecture facing the Bois de Boulogne
Located in the heart of the highly prestigious Maurice Barrès · Les Sablons district, the residence unfolds its spectacular volumes over several levels. The property is structured around a majestic courtyard of honour and a 245 sq m landscaped garden, offering a rare perspective entirely shielded from onlookers. The reception rooms, spread over the garden level and the first floor, open onto an unobstructed view of the edge of the Bois de Boulogne and the bold curves of the Fondation Louis Vuitton. The upper floors are dedicated to family privacy with eight suites, each featuring its own dressing room and independent bathroom. The top level is crowned by a master suite bordered by a running balcony, topped by a 105 sq m roof terrace offering a 360-degree panorama. In the basement, two complete levels house a swimming pool, a hammam, a gym, as well as high-end technical spaces.
The location of this property directly bordering the woods is a privilege sought after by a demanding clientele. The seamless transition between the mineral elegance of the courtyard of honour and the lush softness of the 245 sq m private garden creates a country estate atmosphere, just a few minutes from the centre of the capital. Natural light floods into the 16 main rooms thanks to generous openings and ideal exposure, highlighting the exceptional volumes of each living room. The presence of the double basement level dedicated to leisure and well-being meets the most contemporary standards of modern comfort, where the indoor swimming pool and private hammam become essential amenities for this level of the market.
The choice of absolute rarity in Neuilly
The choice to settle in the Maurice Barrès · Les Sablons district is no coincidence. This sector is historically recognised as the most exclusive in the municipality of Neuilly-sur-Seine. It offers its residents a living environment of absolute tranquillity, while maintaining immediate proximity to the shops on the rue de Chartres and the best schools in the west of Paris. For a buyer seeking discretion, this neighbourhood represents the perfect compromise between bustling Parisian life and the reassuring calm of a high-end residential suburb, favoured by business leaders and major heritage families.
The exceptional valuation of the west of Paris
In a West Parisian market where land is particularly constrained, finding a single-family property of this scale is exceptional. Indeed, most of the municipality’s large historic private mansions have been divided into collective apartments over the decades. For the buyer, beyond the living space, it was the impossible-to-recreate features that dictated the purchasing decision. The complete absence of onlookers combined with an unobstructed view of the surrounding nature constitutes a unique heritage asset. Such a property only becomes available barely once a decade in Neuilly-sur-Seine, which explains the interest generated by this extraordinary case.
A detailed analysis of the valuation of this type of property shows that value is no longer dictated solely by the price per square metre, but by the extreme rarity of the original configuration. Investors describe these assets as immune to short-term fluctuations, as their intrinsic value rests on their irreproducible character. The ability to gaze at the trees of the Bois de Boulogne from one’s living room, without any visual obstruction, gives the location a substantial rarity premium that the wealthiest buyers are willing to pay to secure an unparalleled living environment.
The historic appeal of foreign dynasties to Neuilly’s heritage
The sale of this residence also highlights the unique history of these large estates in the west of the capital, which have often served as holiday residences or private embassies for foreign sovereign families. The Moroccan royal family, like other dynasties from the Middle East and North Africa, has traditionally built up significant real estate portfolios in these prestigious residential sectors. These properties represented strategic anchor points in Europe, chosen for the security offered by the municipality of Neuilly and proximity to major Parisian decision-making centres.
The gradual divestment of certain states or princely families from these colossal assets is now paving the way for a redistribution of the cards. Residences of this scale, once inaccessible and kept for several generations within state or royal estates, are returning to the open market. This shift in ownership towards private Western buyers, and more particularly French ones, reflects a profound change in the ownership of large properties in Île-de-France, which are now perceived as primary residences for local entrepreneurs or industrialists.
The dynamics of luxury real estate in Neuilly-sur-Seine
The real estate market in Neuilly-sur-Seine is structured around a two-tier speed well identified by industry professionals. On one hand, the market for standard three- or four-room family apartments is undergoing the classic adjustments linked to credit access conditions for upper-management households. On the other hand, the exceptional property segment, whose value far exceeds standard benchmarks, operates in a closed loop. This micro-market does not obey traditional economic cycles, but rather a logic of pure opportunity where the extremely limited supply creates its own demand.
An ultra-luxury market immune to the crisis
Although the municipality’s traditional residential market shows relative stability, with an average price of €10,800/sq m in the first half of 2026, the ultra-luxury segment obeys very different rules. Up 1.1% over the last quarter despite a slight annual decline of 1%, the overall market demonstrates remarkable resilience. But as soon as the symbolic €5 million mark is crossed, the dynamics accelerate. The prestige segment remains supported by a wealthy French clientele with significant capital and free from credit conditions. These buyers exclusively target perfect addresses, without the slightest flaw, ready to weather economic cycles.
For this category of very high-end buyers, real estate acquisition is akin to a long-term financial arbitrage. Faced with the volatility of financial markets, prestige property in the west of Paris stands as the ultimate safe haven. The strength of prices in this niche is explained by the physical scarcity of available plots and the constant attractiveness of the municipality. Neuilly-sur-Seine indeed offers a preserved and secure environment, nationally renowned schools, and a privileged living environment, fundamental criteria for families with significant wealth wishing to secure their capital in a tangible asset.
The return of major renovation projects
Buyers’ appetite for properties requiring structural work marks a break with the immediate post-pandemic period, when demand was concentrated almost exclusively on fully completed and decorated interiors. Today, ultra-luxury buyers have accepted that to obtain the perfect location, they must agree to deal with interiors that need redesigning. This approach involves collaborating with renowned architectural firms and skilled craftsmen capable of restoring period features while integrating state-of-the-art home automation technologies.
The return of major renovation projects
This major transaction highlights a notable change in the selection criteria of very high-end buyers. While the trend in recent years favoured turnkey, immediately habitable residences, buyers are once again accepting major renovation projects. Location and the rarity of the view now take precedence over the building’s state of preservation. Wealthy clients no longer hesitate to undertake heavy restructuring work to shape a home in their own image. This strong trade-off confirms that in prestige real estate, the absolute address remains the only truly immutable criterion.
The implementation of these large-scale projects requires specialised technical expertise, particularly for properties with basement levels or contemporary extensions like the 105 sq m roof terrace. The new owners do not hesitate to invest substantial budgets to modernise energy systems, optimise perimeter security, and create bespoke living spaces. By embarking on such projects, these buyers are not just purchasing a place to live: they are actively participating in the preservation and modernisation of the architectural heritage of the west of Paris, embedding their approach in the very history of these exceptional properties.
