Mareterra Monaco: guide to the new seafront district
Published on:
Key Takeaways
Mareterra redefines Monaco's real estate landscape as a new district reclaimed from the sea, located between Port Hercule, the Grimaldi Forum and Larvotto, progressively delivered from the end of 2024.
The project represents a major extension created over the Mediterranean Sea, with an estimated construction cost of several billion euros, and is part of the Principality's long-term urban strategy.
Mareterra offers an extremely limited residential supply, composed of high-end apartments, exceptional villas and townhouses, with generous volumes and ultra-premium amenities.
The district is set to become a new benchmark on the Monegasque waterfront, alongside the renovated Larvotto, the Jardins d’Eau, the Renzo and the waterfront villas.
In 2025, the impact of the waterfront is already visible in market data: Larvotto crosses the symbolic threshold of €70,000/sqm, with an average price estimated at €71,167/sqm according to the IMSEE.
The extremely limited supply and the international architectural signature position Mareterra as a new benchmark for Monaco's ultra-premium market.
Introduction to Mareterra Monaco
Mareterra is the most ambitious land reclamation project ever undertaken by the Principality of Monaco. Located at the eastern entrance of the territory, this new district reclaimed from the sea stretches between the Grimaldi Forum, Port Hercule and Larvotto beach.
Initiated in the early 2010s and progressively delivered from the end of 2024, this complex includes iconic luxury buildings such as Le Renzo and Les Jardins d’Eau, highly rare villas, townhouses, a marina and promenades opening onto the Mediterranean.
This guide explores the signature architecture, premium positioning, international appeal and the impact of Mareterra on the Monegasque real estate market.
In a market where the average price per square metre reaches €57,569/sqm in 2025, Mareterra stands out as a unique product: rare, new, waterfront, sustainable and aimed at an ultra-prime international clientele.
Mareterra Monaco: a new district born from the sea
The project, also known as Anse du Portier, was officially launched by Prince Albert II in the first quarter of 2013. Its completion relied on several major preparatory phases: maritime structure, caissons, backfilling, urban landscaping and environmental integration.
The creation of this territory required colossal maritime infrastructures:
concrete caissons to stabilise the ground;
sediment dredging and prior environmental rehabilitation;
progressive backfilling to create a stable foundation;
design adapted to maritime, climatic and seismic constraints.
Mareterra was designed to withstand sea-level rise and integrate sustainable solutions to ensure the safety and longevity of the environment.
The district's purpose is resolutely high-end residential, with public amenities — promenades, esplanades, green spaces — accessible to the entire population.
This new extension directly enhances the appeal of Monaco's waterfront, which is already boosted by the renovation of Larvotto and the delivery of ultra-luxury residences seen in recent years.
A signature architecture for an iconic district
The architectural direction combines several international signatures. Valode & Pistre, a renowned French firm, developed the master plan with particular attention paid to the harmony of the waterfront.
The Renzo Piano Building Workshop, founded by the Italian architect Renzo Piano, brings a contemporary signature opening onto the Mediterranean. Michel Desvigne, a world-renowned landscape architect, shaped the green spaces and promenades.
The layout of the district prioritises:
clean lines and light colours integrating with the Mediterranean coastline;
a harmonious progression of heights from east to west;
predominantly pedestrian circulation;
vehicular traffic largely diverted underground;
continuity between residential spaces, gardens, promenades and the marina.
This approach distinguishes Mareterra from a simple real estate project. The development functions as a true destination district, designed to combine architecture, landscape, gentle mobility and ultra-premium residential life.
The iconic residences: Le Renzo and Les Jardins d’Eau
Le Renzo dominates the western end of the district, overlooking the marina and the shopping square. This flagship building houses apartments and penthouses with generous volumes: dual-aspect layouts, exceptional ceiling heights, sliding glass doors and Mediterranean panoramas.
Luxury residences such as Le Renzo and Les Jardins d’Eau offer views of the Mediterranean Sea and prestigious finishes. Services include a swimming pool, spa, fitness room, high-end concierge and secured car parking.
Les Jardins d’Eau offer a more intimate atmosphere: residences surrounded by landscaped gardens, vast balconies and private terraces.
These two complexes become new benchmarks of Monaco's skyline, particularly in a market where new builds and residences constructed after 2020 benefit from a significant premium. According to the IMSEE, properties built between 2020 and 2029 show an average price estimated at €65,602/sqm in 2025.
Villas and townhouses: the ultimate rarity in Monaco
Mareterra offers an extremely limited collection of exceptional villas, including several on the frontline facing the sea. The villas are designed with unique architecture, integrating large volumes and harmonious indoor and outdoor living spaces.
These properties offer:
possible private pools;
gardens and roof terraces;
direct access to maritime promenades;
frontline views of the Mediterranean;
maximum privacy due to low density;
parking spaces and annexes tailored to an ultra-high-net-worth clientele.
Townhouses represent an intermediary between an apartment and a villa: townhouses over several floors, interior patios, family-sized volumes and private outdoor spaces.
This type of property is almost impossible to find elsewhere in the Principality, significantly boosting its heritage value.
This rarity aligns with a strong trend observed in IMSEE data: in 2025, more than eight out of ten new build sales concern properties with three or more bedrooms, and the majority of new sales exceed 20 million euros.
An exceptional eco-district: innovation and sustainable development
Mareterra is presented as Monaco's first eco-district, integrating advanced green technologies.
The thermal energy grid harnesses seawater energy to heat and cool the buildings, in synergy with the existing Larvotto network.
Environmental initiatives include:
solar panels on the roofs;
heating and cooling systems using marine resources;
water harvesting and management systems;
reduction of above-ground car presence;
priority given to pedestrian and cycle flows;
extensive greening of the district.
These innovations contribute to Monaco's carbon neutrality target by 2050, championed by Prince Albert II.
Eco-design guides every element of the project, from construction to daily operations. For international buyers, this environmental dimension adds functional and reputational value to an already extremely rare asset.
Green spaces, biodiversity, and quality of life
The district offers a public park, coastal promenades, and numerous landscaped areas. Lush green spaces are laid out, featuring a Mediterranean palette tailored to the climate and the seafront.
Mareterra will be primarily pedestrianised, promoting a healthy and serene lifestyle. Underground car circulation allows for the preservation of public spaces on the surface and enhances the comfort of both residents and visitors.
The Princess Charlene Swimming Pool illustrates this art of living focused on the sea, sport, and well-being.
This combination of sea, green spaces, soft mobility, and contemporary architecture is rare in Monaco, where available land is extremely limited. It explains why Mareterra is perceived as a new standard in sustainable residential luxury.
Mareterra, a new hub of attraction for international buyers
Monaco represents a global stronghold for high-net-worth individuals: safety, political stability, advantageous taxation, and a Mediterranean lifestyle on the Côte d’Azur.
Mareterra helps support the luxury and high-end real estate sector in Monaco by bringing an unprecedented product: a new, coastal, sustainable, and ultra-exclusive district.
The appeal relies on:
extreme rarity;
exceptional maritime views;
immediate proximity to the Carré d’Or, Monte-Carlo, and Larvotto;
a destination-district with a marina, boutiques, restaurants, and promenades;
signature architecture;
an ultra-premium positioning.
This attractiveness is part of an overall very solid market. In 2025, Monaco recorded 493 property transactions, up 5.8% compared to 2024, for a total value of 5.9 billion euros.
Ultra-premium positioning and tailor-made services
The amenities match international standards of the ultra-high-end: 24/7 concierge, permanent security, valet parking, well-being spaces, swimming pools, and spas.
Privacy is guaranteed by controlled access, underground car parks, meticulous residential services, and low density for the most exclusive properties.
This level of service brings Mareterra closer to iconic districts of Dubai, Miami, or Hong Kong, while retaining Monegasque scale, security, and charm.
Additional services can include rental management, private event organisation, maintenance, security, and personalised support.
In a market where buyers are increasingly selective, the level of service, quality of construction, sustainability, views, and privacy are becoming criteria just as important as the price per square metre.
Impact of Mareterra on the Monegasque real estate market
Land scarcity in Monaco keeps prices among the highest in the world. Mareterra introduces a new asset class: ultra-premium, brand-new beachfront properties, designed to meet the current expectations of billionaires and wealthy buyers.
The district serves as a new qualitative benchmark, influencing prices in neighbouring districts like Larvotto and the Carré d’Or.
The impact of the seafront is already reflected in official figures. In 2025, Larvotto became the most expensive district in Monaco with an estimated average of €71,167/sqm. The district also recorded only 13 resales, but for an exceptional total value of 851.9 million euros, driven by the arrival of recently built properties on the market.
The reclamation of land from the sea linked to the project remains a subject of ecological debate, but the heritage dimension attracts long-term investors.
The majority of opportunities are handled off-market given the required confidentiality, the scarcity of supply, and the profile of the buyers.
Mareterra and the redefinition of the Monegasque seafront
The project is part of a global urban strategy linking renovations of Larvotto, the Grimaldi Forum, and the arterial routes to Port Hercule.
This new pedestrian continuity from the beach to the quays reinforces Monaco's international image as a showcase for sustainable innovation, coastal urban planning, and residential luxury.
The redesigned seafront amplifies appeal during major events:
F1 Grand Prix;
conferences at the Grimaldi Forum;
cultural events;
nautical events;
international gatherings linked to luxury, finance, and yachting.
Mareterra is therefore not limited to a residential complex. The district contributes to the transformation of Monaco's image, linking heritage prestige, environmental innovation, and seafront quality of life.
Living and investing in Mareterra: who is the district for?
The typical profile of buyers includes:
international families seeking safety and quality schools;
entrepreneurs and wealth investors;
yacht owners drawn to the marina;
collectors of rare properties prioritizing location and signature architecture;
residents looking for a new, sustainable, and ultra-private asset.
The rental supply will remain limited and high-end, with rents in line with the level of amenities.
To identify available opportunities and understand regulatory specificities, it is recommended to get in touch with a specialist in Monegasque real estate.
In a market where the average sales price for new builds reached 40.8 million euros in 2025, Mareterra naturally targets a clientele capable of positioning themselves on the Principality's rarest assets.
