Monaco’s $2 Billion Land Reclamation Project Is Fueling a Record-Breaking Real Estate Market

Monaco has long been synonymous with luxury, and its real estate market continues to live up to that reputation. In fact, it's consistently been the most expensive place on the planet to buy prime residential property. According to the 2025 Knight Frank Wealth Report , a cool $1 million will get you just 205 square feet of space in this glittering microstate on the French Riviera. For context, that's about the size of a small studio apartment. 

At just 510 total acres, Monaco is the second-smallest country in the world, trailing only Vatican City. To give you some perspective, Monaco is smaller than New York's Central Park, which spans 843 acres. But what it lacks in space, it makes up for in exclusivity. With a population density that's the highest in the world—18,681 people per square kilometer—available land is a rare commodity. So, when space runs out, Monaco has a solution: reclaim land from the sea.

The €2 billion ($2.1 billion) Mareterra land reclamation project , which added 15 acres to Monaco's coastline, is just one example of how the tiny principality is expanding its territory to meet the growing demand for high-end real estate. And it's working. Designed by architectural heavyweights Renzo Piano and Sir Norman Foster, this development is setting new records. Some of the luxury homes in Mareterra are fetching over €100,000 (about $108,000) per square meter—more than double the average price of resales in the region.

Monaco's appeal goes beyond its prime real estate. The principality's no-tax status—no income, capital gains, or wealth taxes—makes it a magnet for the world's wealthiest individuals. Throw in its perfect Mediterranean climate, world-class healthcare, political stability, and high levels of privacy and security, and it's no wonder Monaco remains a top destination for UHNWIs . 

However, all this exclusivity doesn't come cheap. In 2024, newly built properties in Monaco soared to an average price of €36.4 million ($39.6 million), six times the price of a resale property. But even at these sky-high prices, demand remains strong. Homes in Monaco routinely exceed €40 million ($43.5 million), and even a parking spot can cost an eye-watering €395,000 ($430,000). 

Monaco has also retained its title as the world's most expensive luxury rental market. A modest two-bedroom apartment in Monaco can set you back around $30,000 a month, with a 1,100-square-foot property starting at about $19,350 monthly.
