Envisioned as Monaco’s “greenest corner,” the groundbreaking Mareterra project is not just an urban extension; it’s a monumental achievement that sets unprecedented global standards for sustainable coastal urban development. This ambitious undertaking seamlessly blends cutting-edge environmental practices with the Principality’s signature luxury, showcasing how growth can be achieved in harmony with nature.
Pioneering eco-friendly design and marine protection
At the very core of Mareterra’s conception is an unwavering commitment to environmental preservation, particularly for the delicate Mediterranean marine ecosystem. From its earliest stages, the project was designed in close collaboration with leading marine biologists, ensuring minimal impact on the surrounding waters. Innovative and highly specialized techniques have been meticulously deployed. This includes the strategic placement of concrete caissons – massive, hollow structures that form the foundation of the new land. These caissons are engineered with intricate reliefs and grooves, specifically designed to encourage the rapid colonization and flourishing of native marine flora and fauna, effectively creating new underwater habitats. Furthermore, a monumental effort has been undertaken to transplant Posidonia oceanica seagrass, a vital protected species crucial for marine biodiversity and oxygen production, from the development area to new, thriving locations. This proactive approach underscores Mareterra’s dedication to not just mitigating harm, but actively enhancing ecological value.

Harnessing cutting-edge green technologies
Mareterra is a living laboratory of green technologies, demonstrating a holistic approach to energy efficiency and resource management. Its energy infrastructure is remarkably self-sufficient and environmentally sound. An extensive network of solar panels is integrated throughout the development, strategically placed to harness Monaco’s abundant sunshine and meet an impressive 40% of the project’s total energy needs. A pioneering heating and cooling system leverages seawater (thalassothermal energy), utilizing the stable temperature of the Mediterranean to regulate internal climates with minimal energy consumption. Beyond energy, sophisticated rainwater harvesting systems are implemented to capture and reuse precipitation for irrigation and other non-potable uses, significantly reducing freshwater demand. Finally, expansive green roofs are a prominent feature, providing insulation, reducing urban heat island effects, managing stormwater, and creating additional green spaces that contribute to biodiversity.
Thoughtful spatial planning and public green spaces
The design philosophy of Mareterra prioritizes public accessibility and green living. A remarkable half of the entire new area is dedicated to public spaces, fostering a vibrant and interconnected community. This includes beautifully landscaped parks, extensive pedestrian walkways that encourage strolling and connection, and dedicated cycle paths promoting sustainable transport. A monumental landscaping effort is underway, with over 1,000 trees being planted, transforming the new district into a verdant oasis. A particular highlight is the creation of a 1-hectare pine forest, offering residents and visitors a significant natural haven for relaxation and recreation, unprecedented in such a densely developed urban coastal setting. This commitment to green infrastructure enhances the quality of life and provides vital ecological corridors.
Seamless integration of luxury and sustainability
While Mareterra sets global benchmarks for ecological design, it simultaneously embodies the epitome of Monégasque luxury. The project features exquisite luxury residences that offer unparalleled living experiences, complemented by a bespoke marina designed for superyachts and exclusive vessels. A beautifully crafted seaside promenade invites leisurely strolls, connecting residents with the stunning coastal environment, while thoughtfully designed commercial spaces offer high-end retail and dining experiences. This seamless integration of ultra-luxury with robust environmental principles positions Mareterra’s real estate among the most coveted and valuable globally. It stands as a testament to Monaco’s vision of creating a future where economic prosperity, ecological responsibility, and opulent living are not mutually exclusive, but intrinsically linked.
