What Mareterra does

Mareterra is a sovereign-backed luxury real estate development project in Monaco, executed by SAM L'Anse du Portier under the patronage of HSH Prince Albert II of Monaco. The project created 6 hectares of new land along Monaco's coastline between the Grimaldi Forum and the Formula One Grand Prix tunnel, delivered as a self-contained eco-district comprising approximately 50 apartments in the Le Renzo building designed by Renzo Piano, hillside Villas de la Colline, Jardins d'Eau waterfront residences, a Mediterranean-style animated port, and public amenities including the Piscine Princesse Charlène, Place Princesse Gabriella, and Promenade Prince Jacques. Construction ran from the 2013 announcement through a 2015 Concession Treaty, culminating in official inauguration on December 4, 2024.

The project is differentiated by proprietary marine eco-design technology rather than conventional real estate differentiation. Eighteen reinforced concrete caissons, each 28m wide, 27m high, and weighing 10,000 tonnes, were embedded with Jarlan damping chambers to absorb wave energy and double as artificial reef habitats with ecological corridors supporting marine biodiversity colonization. The district runs a thalassothermal energy loop — seawater-fed heat pumps covering 80% of heating and cooling needs — supplemented by 9,000 m² of solar panels, 200 EV charging stations, and smart grid infrastructure (intelligent meters, astronomical-clock lighting, presence sensors, battery storage). 800 trees, 27,000 m² of planted area, and 19,000 m² of car-free pedestrian zone support sustainability certifications including HQE Stage 4, BREEAM Excellent, BiodiverCity, Clean Ports, and EVE.

Mareterra's revenue model is one-time luxury property sales directly to high-net-worth individuals and real estate investors, with no public pricing and multi-year contracting via SAM L'Anse du Portier. Marketing leverages PR in Architectural Digest, Robb Report, and Financial Times How To Spend It, alongside organic social (Instagram, LinkedIn) and official website content. Strategic partners include Renzo Piano Building Workshop, Valode & Pistre Architectes, and Michel Desvigne Paysagiste for design, with Bouygues TP Monaco as the core construction contractor. The project is wholly owned under SAS Le Prince Albert II de Monaco, with permanent staffing of 11–50 (scaling to 800+ at peak construction).
