Mareterra

Mareterra is Monaco's most ambitious recent urban project, a new eco-district built on six hectares of land reclaimed from the sea adjacent to Larvotto, the Principality's eastern seafront district. Completed across several phases from 2024 to 2025, Mareterra introduces 110 residential units across low-rise buildings of eight floors, a private harbour with thirty-five berths for small vessels, three hectares of public gardens and green spaces, retail, restaurants, and the environmental infrastructure that positions it as Monaco's most ecologically considered development. The project places Monaco's most recent residential addresses at literally sea level, with the closest buildings ten metres from the Mediterranean.

At one hundred thousand euros per square metre, Mareterra represents Monaco's highest residential price point, a reflection of the combination of entirely new construction, exceptional sea proximity, private harbour access, and the prestige of being the Principality's newest district. The low-rise eight-floor maximum reflects a planning decision to keep building heights below those of existing Larvotto buildings, maintaining the visual character of the seafront while maximising the horizontal relationship between residences and the gardens and harbour.

Mareterra's price per square metre of one hundred thousand euros places it alongside Monaco's highest-value addresses, including the Tour Odéon sky penthouse and the most elevated Carré d'Or transactions. What distinguishes Mareterra from those addresses is the combination of entirely new delivery, ecological design credentials, private harbour access, and the residences' direct relationship with the water. Buyers here are purchasing in Monaco's newest district, which has no existing resale history to compare against but which carries the premium of scarcity and newness in a market where new land is genuinely irreproducible.

The 110-unit total across the residential buildings is limited relative to the project's profile, meaning supply will remain tightly controlled in the secondary market for years after initial delivery. For buyers who acquired during the development phase or who purchase in the early secondary market, the asset's scarcity relative to its profile supports the price level across market cycles.

Mareterra extends Larvotto eastward, sitting beyond the existing Grimaldi Forum convention centre and the Larvotto beach. Avenue Princesse Grace runs from Monte-Carlo through Larvotto to the Mareterra boundary, giving residents a coastal road connection to Monaco's commercial centre. The new district's internal gardens and promenades provide a self-contained walking environment that is distinct from the rest of the Principality.

The private harbour gives Mareterra residents direct water access not available from any other Monaco residential address on this scale. CAM bus services extending to Larvotto provide connections to Monte-Carlo and the rest of Monaco without requiring a car. For residents with yachts or small vessels, the thirty-five-berth private harbour integrated into the district provides operational convenience directly from the residential buildings.
