An ambitious and sustainable extension project

Faced with Monaco's limited territory, the Prince's Government launched a 6-hectare offshore extension project in 2015 at a cost of around €2 billion. The stated objective was to create a new exemplary district, reconciling architectural innovation and environmental excellence. After nearly a decade of work, initiated in 2013 and completed at the end of 2024, Mareterra has become a reality, marking a historic turning point in the Principality's urban planning. This eco-district is a continuation of Fontvieille (the previous extension from the 1970s) by offering modern infrastructure to meet Monaco's growth, while meeting the ecological challenges of the 21st century.

Renowned architects were selected to design Mareterra. The master plan was entrusted to the Valode & Pistre group (architects Denis Valode and Jean Pistre) alongside the Renzo Piano Building Workshop, the famous agency of Pritzker Prize winner Renzo Piano. The landscape architect Michel Desvigne designed the green spaces. Together, these experts have imagined a harmonious district that blends naturally into the existing coastline, with contemporary buildings of great prestige and a particular attention paid to marine and terrestrial ecosystems.

An ultra-luxurious and exclusive district

Mareterra is not only a feat of environmental engineering: it is also a new ultra-luxury hub that enriches Monaco's real estate offer. In total, the district is home to 110 luxury apartments and 10 exceptional villas, all designed for the most demanding clientele. These top-of-the-range residences offer dimensions rarely seen in Monaco (several apartments reach or exceed 1000 m²) as well as services worthy of palaces: private swimming pools, spas, 24-hour concierge services, hotel services, secure parking, etc. Unsurprisingly, Mareterra has established itself as one of the most exclusive addresses in Europe – with prices per square metre reaching record levels of around €100,000 , and even up to €120,000 – €150,000 for the most prestigious properties. The demand to reside or invest there is much higher than the supply, which gives these properties great rarity and a high potential for valuation.

Mareterra's iconic residences

The new district consists of several iconic real estate complexes, each with its own architectural identity:

• The Renzo – A modern 17-storey tower designed by Renzo Piano, located at the western end of the district. Overlooking the port of Mareterra, Le Renzo is home to bright through apartments (singles, duplexes, triplexes and even a quadruplex penthouse) with panoramic views of the Mediterranean. Residents enjoy exclusive amenities such as a private seawater pool (the Princess Charlene Pool) on the rooftop, valet parking and an ultra-available concierge service. This signature building, a true "lighthouse" of the project, symbolises the link between Monaco and the sea.
• Les Jardins d'Eau – A set of four prestigious buildings designed by the architect Denis Valode, in the heart of a vast wooded park. These architecturally elegant residences feature staggered heights and are surrounded by Mediterranean vegetation, giving the impression that the buildings emerge from a lush garden. Les Jardins d'Eau offers very large apartments extended by large balconies, inviting you to live in the open air. They also offer high-end amenities to their occupants: indoor swimming pools, gyms, wellness areas, wine cellars, private lounges, etc.
• Mareterra Villas – Nestled on the seafront, six ultra-luxury villas form a unique real estate collection. Each of these villas is unique in its architecture, inspired by the spirit of the Belle-Époque mansions while integrating technology and contemporary design. With vast indoor and outdoor areas, private gardens and swimming pools, these villas offer an unrivalled level of prestige. Their very limited number makes them particularly coveted gems.
• The Townhouses – Harmoniously integrated into the landscape of the district, a few townhouses complete the residential offer of Mareterra. Surrounded by greenery, these homes benefit from an innovative and bright interior patio, creating a well of greenery in the very heart of the house. They offer the privacy and charm of a city villa, combined with the modern advantages of a brand new eco-district.

All these residences share an exemplary level of finish and sustainable features (integrated solar panels, home automation management, optimized sound and thermal insulation, etc.). Mareterra offers a living environment of rare quality, where every detail has been thought out to combine luxury, comfort and durability.

Living environment: marina, green spaces and neighbourhood life

Beyond the accommodation, Mareterra has been designed as a real lively living space open to the sea. The district has a new marina called Port du Petit Portier, which can accommodate about fifteen pleasure boats. Around this human-sized marina, a pleasant pedestrian esplanade hosts local shops and high-end restaurants, making Mareterra a popular place to relax for residents and visitors alike. A new public square – the Place Princesse Gabriella – is the commercial and friendly heart of the district, reinforcing the animation and life of the neighbourhood.

Green spaces occupy a central place in the development. Around 27,000  m² of parks and gardens planted with more than 800 trees have been created, offering a real green lung by the sea. A large landscaped park runs along the coast, incorporating Mediterranean species, shaded paths and even devices to promote biodiversity (insect hotels, bird nesting boxes, etc.). Residents and walkers can enjoy an immersion in nature without leaving Monaco, with the added bonus of the lapping of the sea in the background.

In terms of mobility, Mareterra largely favours pedestrian and bicycle traffic. The district is almost entirely pedestrianised, with around 21,000  m² of pedestrian spaces, and has 600 metres of safe cycle paths. A continuous coastal promenade now allows you to walk or jog along the sea, connecting the new district to the Grimaldi Forum on one side and the Larvotto beach on the other. This continuation of the customs path offers an exceptional panorama of the bay. For vehicles, a large capacity underground car park serves the district, keeping the surface free of all cars and reducing nuisance. Thanks to these developments, Mareterra embodies an art of living focused on well-being, conviviality and soft mobility.

On the economic level, the creation of this tenth district should also generate a new hub of activity in the Principality. The installation of shops and infrastructure in Mareterra will promote local employment and diversify the offer of services for residents. In the long term, Mareterra will contribute to boosting the Monegasque economy while enriching the country's attractiveness to international investors and visitors.
