Inside Mohammed bin Salman’s USD 300 Million French Mansion
Although it appears centuries old, Château Louis XIV is a contemporary creation — a 5,000-square-metre residence outside Paris designed to capture the architectural grandeur of France’s royal past while functioning as one of the world’s most technologically advanced private homes with its own aquarium and indoor pool. Located in Louveciennes, west of Paris, Château Louis XIV is among the most distinctive estates in Europe’s ultra-luxury property market. More than a decade after its completion and record-setting sale, the estate remains a benchmark in luxury real estate, illustrating how global wealth continues to reshape Europe’s architectural landscape. LUXUO takes a closer look at one of the world’s most expensive luxury homes purchased by Mohammed bin Salman.
The estate was developed by Emad Khashoggi through his firm COGEMAD. Construction began in 2008 on land that previously hosted a 19th-century manor. The design deliberately references the palaces of Louis XIV, combining symmetry and formal grandeur with contemporary engineering and building technology.
Spanning roughly 57 acres, the property features formal gardens, fountains and reflecting pools arranged in the geometric tradition of the nearby Palace of Versailles. While the exterior mirrors the scale and balance of France’s classical royal estates, the structure functions as a fully contemporary private residence.
Inside, the mansion covers approximately 5,000 square metres. Marble halls, gilded ornamentation and grand staircases reference historic French interiors, yet its infrastructure — including lighting, climate control and security — is fully automated and digitally managed.
The 2015 Record-Breaking Property Purchase
The property returned to the headlines in 2015 when it was reportedly acquired for around USD 300 million by Mohammed bin Salman through companies connected to the Saudi royal court. At the time, the transaction was widely reported as the most expensive residential property sale in the world. The purchase reflected the growing role of global wealth in shaping the ultra-luxury market, particularly in prime European locations. Designed to accommodate both privacy and entertaining, the estate includes a cinema, spa, reception rooms, extensive wine storage and other facilities for large-scale gatherings.
One of its most striking features is an underwater viewing chamber beneath the reflecting pool. Encased in thick glass, the space allows occupants to sit below the waterline while fish swim overhead — a fusion of spectacle engineering and classical aesthetics that has drawn consistent media attention. The sale was notable not just for the price but for the property’s deliberate homage to France’s royal architectural legacy, merging historic inspiration with modern comfort.
Renewed Attention During the Newcastle United Takeover

Although the purchase occurred in 2015, the estate re-entered public conversation in 2020 and 2021, when international media covered the Saudi-backed acquisition of Newcastle United. The takeover — led by Saudi Arabia’s Public Investment Fund — brought renewed scrutiny to Mohammed bin Salman’s global property holdings and financial footprint. In this context, Château Louis XIV is often cited as an emblematic example of ultra-high-net-worth property ownership. While the estate remains private, its combination of scale, design and record-setting purchase price ensures it continues to be referenced in discussions of luxury real estate and architecture.
More than a decade after its completion, the mansion remains a rare case of a newly built European estate intentionally designed to replicate the visual language of France’s royal past — a property that sits at the intersection of heritage, technology and global affluence.
