With a transaction valued at an estimated €471 million, Ukrainian billionaire Rinat Akhmetov has completed one of the world’s most expensive residential sales, in the heart of Monaco’s new Mareterra district.
The ultra-luxury real estate market has just reached a new historic milestone. Ukrainian businessman Rinat Akhmetov, considered the wealthiest man in his country, has purchased an exceptional apartment in Monaco for €471 million. A true record !
Mareterra, the new sanctuary for the ultra-wealthy
The property is located in the Le Renzo building, within Mareterra, a seaside extension inaugurated in late 2024 that has become one of the world’s most expensive addresses in just a few months. This real estate project, built on land reclaimed from the Mediterranean, attracts a wealthy international clientele seeking exclusivity and discretion.
Indeed, while real estate prices per square meter hover around 50,000 euros in Monaco, prices in Mareterra push all boundaries: they are said to exceed 100,000 euros per square meter, and rents could even reach 150,000 euros per month.
The apartment purchased by the billionaire is, in fact, more akin to a vertical residence than a simple pied-à-terre : spread over five levels, it spans approximately 2,500 m² and comprises no fewer than 21 rooms.
