Beyond conventional disclosure
The real estate process is inherently asymmetric. While a seller knows the property intimately, a buyer often enters the transaction with incomplete data and under compressed timelines. Mandatory diagnostics fulfill a legal obligation, but their scope is narrow by design. They reveal what the law demands, yet they fail to provide what a sophisticated buyer needs to make a confident decision—or the evidence a seller needs to translate the true, intrinsic value of a prestige estate.
The result: price negotiations conducted on guesswork, conditional clauses that delay or kill transactions, and post-acquisition surprises that erode both value and trust.
The Property Passport
We establish a new standard of trust in exceptional real estate. The Heritage certification is the result of an on-site inspection, conducted by an independent certified building expert and enriched by proprietary Heritage intelligence.
We reach what mandatory diagnostics never touch. By documenting every material fact that defines value, we transform uncertainty into absolute confidence for buyers, sellers, and the advisors who serve them.
More than a report, it is a signed record of your property’s DNA: where every finding is rated, every rating is explained, and every page is built to protect your legacy.

Selected Properties & Track Record
Every exceptional property possesses a unique technical DNA. From 19th-century Basque estates to contemporary architectural masterpieces on the Riviera, Heritage has decoded the complexities of the most significant assets in the French and Swiss prestige market. These case studies represent our commitment to transparency and our role as the trusted forensic baseline for high-stakes transactions.


VILLA MILADY - Biarritz
Perfectly situated in one of Biarritz's most sought-after residential addresses, Villa Milady is a rare synthesis of Basque architectural tradition and refined contemporary design. The property commands sweeping, unobstructed views over the Atlantic — a backdrop that defines both its character and its enduring value.
At the seller's initiative, a full Heritage assessment was commissioned prior to listing — covering the structural envelope, technical systems and all key installations — providing prospective buyers with independently verified documentation and complete peace of mind.


APPARTEMENT MAJESTIC - Biarritz
Ideally positioned on Avenue Reine Victoria, in the prestigious Palais quarter, this 220 sq. m. apartment graces the fifth floor of a distinguished residential building. The property offers four bedrooms and four bathrooms, with luminous, well-proportioned rooms and an enviable setting just moments from the ocean.
On the buyer’s behalf, our heritage consultants conducted a thorough review of the building’s shared infrastructure — common areas, facade, roof and collective systems — delivering a certified report that informed the acquisition with rigour and full transparency.


VILLA CAMP LAUVAS - Mougins, French Riviera
Set at Chemin du Camp Lauvas, this 240 sq. m. residence strikes a perfect balance between modern comfort and refined functionality. The home offers three bedrooms and three bathrooms, set on a meticulously landscaped 1,200 sq. m. plot. A generous 12 × 4 m pool invites leisurely afternoons outdoors, while a double garage rounds out the amenities.
Our firm was retained by the presenting agency to produce an independent condition and Heritage report on the property — offering qualified assurance on the fabric of the building and the garden’s key installations, and supporting a smooth, fully documented transaction.


VILLA YIN YANG - Mougins, French Riviera
Nestled within the highly coveted Domaine des Parcs de Mougins, this remarkable property offers 395 sq. m. of refined living space, set within 3,000 sq. m. of beautifully landscaped grounds.
At the seller’s initiative, a full heritage assessment was commissioned from our firm, covering the landscaped grounds, pool infrastructure and boundary features — providing prospective buyers with independently verified documentation and complete peace of mind.
