Mareterra: New and ultra-luxury real estate in Monaco
Six hectares reclaimed from the Mediterranean, a new seafront, residences designed by leading names in architecture and some of the most exclusive properties in the Principality: Mareterra has created a real estate market in Monaco unlike any other.
In Monaco, where every square meter of land is a precious resource, Mareterra is not simply a new real estate development. It is a new piece of the Principality, created on the sea and conceived simultaneously as a residential area, a landscaped space, a place for strolling and a new ultra-prime address.
The district extends the coastline between the Grimaldi Forum area, Larvotto and the entrance to Monte-Carlo. Its architecture combines apartment buildings, villas, townhouses, public spaces, shops, a small port and Mediterranean vegetation.
The project, formerly known as Anse du Portier, represents approximately six hectares of new land created at sea.
Its design mobilized architects, urban planners, engineers, landscape architects and environmental experts around a particularly high ambition: to create a new extension of Monaco without treating all the land gained as a simple building surface.
🌊 Mareterra: when Monaco creates a new district on the sea
Land scarcity is one of the fundamental characteristics of the Monegasque real estate market. Mareterra provides a spectacular response to this constraint by physically extending the territory of the Principality.
But the project is not about juxtaposing luxury buildings. The overall plan combines housing, landscape, pedestrian mobility, public spaces and the Mediterranean.
🏛️ What are the residences in Mareterra?
Mareterra's residential offering has been deliberately diversified. It is not based on a single tower or a uniform program, but on several architectural styles and different ways of living on the Monegasque seafront.
The official website specifically distinguishes between Le Renzo, Les Jardins d'Eau, villas and townhouses.
⛵ The Renzo: Mareterra's signature architecture
Designed by Renzo Piano Building Workshop, Le Renzo is one of the most visible architectural signatures of the new district.
Its silhouette is inspired by a fragmented ship and the dialogue between light, air, water and the Mediterranean.
The building overlooks the Petit Portier and its square, at the western end of Mareterra.
🌿 The Water Gardens: volumes, vegetation and sea horizon
Les Jardins d'Eau are developing a more directly landscape-oriented approach to residential real estate.
The buildings are surrounded by Mediterranean vegetation, with large balconies and wide-open views of the sea.
🏡 Villas and townhouses: a very rare offering in Monaco
Mareterra's distinctive feature is also the introduction of individual residential offerings in a market largely dominated by apartments.
The villas of Mareterra
The villas constitute one of the most exclusive segments of the program.
The official website emphasizes that they are produced in limited numbers and that each has its own architecture and organization.
They combine large volumes, an indoor-outdoor connection and open views of the Mediterranean.
The townhouses
The townhouses were designed to blend more into the landscape.
Vegetation covers part of their architecture and each townhouse notably has an interior patio.
This typology provides another way of living in Mareterra, closer to a house than to a traditional collective apartment.
✏️ Three major names at the heart of the project
Mareterra combines several disciplines: urban planning, architecture, landscape and environmental engineering.
🚶 Mareterra is also a district open to Monaco
The ultra-residential nature of the program does not mean that Mareterra is designed as a completely closed complex.
A significant part of the project consists of public spaces, promenades and pedestrian walkways.
🌱 Why is Mareterra presented as an eco-district?
Building on six hectares in the Mediterranean presented a considerable environmental challenge.
The project therefore incorporated measures concerning marine biodiversity, vegetation, energy management, water, mobility and building performance.
💎 How much is real estate worth in Mareterra?
Mareterra belongs to such a specific segment that it would be misleading to mechanically apply an average price per square meter to it.
In the nomenclature used to analyze the market, Mareterra contributes to the Larvotto sector.
But €71,167/m² is not "the price of Mareterra". It is a neighborhood indicator that includes very different properties, buildings and construction generations.
The apartments, duplexes, penthouses, villas and other exceptional properties in Mareterra must be analyzed individually.
The delivery of recent, ultra-high-end developments, including Mareterra, has contributed to transforming the statistics of the Monegasque market. Larvotto has thus become the first area in Monaco to exceed the €70,000/m² threshold in the IMSEE index.
🔍 Why is Mareterra creating a market within a market?
🧐 Buying in Mareterra: what should you look for?
In such an exclusive program, simply comparing the price per square meter is particularly insufficient.
⚖️ Buying in Mareterra: don't forget the acquisition costs
The exceptional nature of the program does not change the need to study precisely the legal and tax regime of the acquisition.
Whether the property is new or resale, and whether it is owned by a natural person or a holding structure, the nature of the transaction can have an impact on the rights and the overall cost.
