Which new real estate projects will reshape Monaco in 2025?

Monaco never slows down. Hardly has one construction project been delivered when another begins. In this compact territory where the price per square metre reaches record highs, real estate keeps redefining the rules of the sector. Buying property in Monaco, whether as a primary residence, secondary home, or rental investment, is now part of a wealth strategy logic. These residences, far more than large-scale developments, are reshaping the contours of luxury and strategic investment. Mareterra, Bay House, Villa Ninetta, Le Lido, and Maison Valentina: a look back at new real estate developments in Monaco and what they signal for the market’s evolution. 

New real estate in Monaco: the projects shaping 2025

The development of new real estate programmes in Monaco follows a dual logic. They enrich the very high-end residential offering and provide investors with rare products, with strong resale and profitability potential within an attractive tax framework.

Latest new real estate projects in Monaco: Mareterra leads the way

Six hectares reclaimed from the Mediterranean. An entire district delivered turnkey to the Principality. Mareterra is not a real estate operation: it is an extension of Monaco. Its name fuelled the media for months, as the programme seemed somewhat surreal. Mareterra has taken the territory to another level in luxury real estate. Inaugurated on 4 December 2024 in the presence of the princely family, it crystallises a vision expressed from the outset by Prince Albert II: to create a place that is both exemplary environmentally and consistent with Monaco’s DNA. Neither pastiche nor rupture: a natural extension of the coastline. The project successfully combines urban planning, ecology, and an exceptional living environment. This eco-district was conceived as a manifesto. Beyond its architectural and environmental ambitions, Mareterra represents an unprecedented heritage asset for any investor seeking to secure an investment in a market with very high land pressure. Designed from the beginning to meet High Environmental Quality standards, Mareterra stands out in substance and form: 

• 9,000 m² of solar panels;

• heating and cooling via marine geothermal energy and heat pumps; 

• 600 m³ rainwater recovery system;

• 50% rainwater reuse;

• 80% of heating and cooling supplied by renewable energy;

• 600 metres of cycle path; 

• 19,000 m² of pedestrian area;

• 27,000 m² of planted surface, including a pine grove of nearly 800 trees.

The quality of design matches the ambitions: Denis Valode, Renzo Piano, Michel Desvigne. Names not brought in just to sign, but to design a sustainable and above all coherent district. Mareterra is above all: 

• 110 apartments;

• 10 ultra-luxury villas; 

• 4 townhouses;

• a marina with 16 moorings.

Bay House: a prestigious new real estate programme in Monaco

Located just a short distance from Anse du Portier, Bay House is one of Monaco’s most emblematic new residences. This large-scale architectural project is part of the broader Testimonio II programme and embodies the new face of Monegasque luxury: 

• 56 prestige apartments;

• 5 villas with rooftop garden terraces;

• 3 to 6 bedrooms per residence.

Its lines evoke the waves of a Mediterranean Sea embraced without restraint by its balconies. The complex rose just steps from the Larvotto beaches. The interiors are very high-end, custom-made by artisans. You will find Emperador Light and White Alabaster marble, walnut, and light wood. 

Residents can also enjoy the 500 square metres dedicated to unique amenities: spa, massage room, hammam, hair salon, relaxation area… everything is refined, thought through, and meticulously planned. It is one of the most complete examples of a new residence in Monaco combining quality of life and real estate value growth. Investors are interested, as are families keen to benefit from the new international school located just metres away. 

Testimonio II: the new residence with integrated school and services

Testimonio II was born from the vision of Groupe Marzocco and VINCI Immobilier. Within its walls, design by Arquitectonica, Alexandre Giraldi, and Laura Sessa is truly inspiring. With its 378 high-standard state-owned apartments suspended above Monaco Bay and its two towers of 30 and 32 floors rising to 100 and 110 metres, the project is dizzying. Launched in the second quarter of 2017, it took seven years for the programme to be completed. A 50-place nursery as well as the new location of Monaco’s international school have found their home there. These projects actively contribute to the emergence of a premium real estate offering in Monaco, marked by growing demands in comfort, services, and sustainability.

Villa Lucia: a youthful revival in Les Moneghetti 

Scheduled for 2026, Villa Lucia is one of those new exceptional residences completing Monaco’s real estate landscape. The project is signed by the excellent Alexandre Giraldi, also known for his collaboration with Lord Norman Foster in designing the Monaco Yacht Club. The villa includes 14 floors and 14 apartments where privacy meets ultra-luxury. To top it all off, a quadruplex with a private pool crowns the building.

Villa Ninetta: a discreet address revitalising Jardin Exotique

From studio flats to three-room apartments, Villa Ninetta and its 27 apartments stand discreetly yet with clear elegance at the foot of the Jardin Exotique district. Built on the very site where Palais Ninetta once stood, this new residence continues a local architectural memory, between heritage and modernity. Without copying the style, it extends its spirit by interpreting the lines of buildings from the “Monegasque Belle Époque” while integrating contemporary requirements for comfort and sustainability.

This major project, designed by Monegasque architect Fabrice Notari, aims to breathe new life into Jardin Exotique, an area that had until now remained on the sidelines of the Rock’s urban dynamics. As with any high-end development in Monaco, residents benefit from exacting features: noble materials, polished finishes, bespoke fittings. The objective: to create a dialogue between heritage and innovation, anchoring Villa Ninetta in Monaco’s landscape in a lasting and confident way.

Le Lido: a high-end residence anchoring the past in the present

Estate agents see it as a project for the future. This ambitious programme will be located on Rue des Lilas. Built on the site of the former villas “Le Lido” and “Les Hirondelles”, Le Lido is rooted in architectural heritage while looking to the future. 11 floors, 20 high-end apartments, 3 parking levels, retail spaces, residential services, premium facilities: the complex offers strong value-growth potential and promises to inject new momentum into the neighbourhood. Its location will be a major advantage for residents, as it is just steps from Millefiori and Buckingham Palace, as well as Monaco’s main points of interest.

La Condamine reinvented with Maison Valentina

Maison Valentina focuses on design and integration with its surroundings. The La Condamine district is therefore preparing for a new lease of life. This real estate project is an ideal opportunity to keep the heart of the Principality beating. Its location is indeed ideal: at the foot of the Rock, near the underground entrance to Monaco station, and just metres from the famous Place d’Armes market. This programme, expected to be delivered in 2026, reflects a clear intention: to highlight the Principality’s historic districts. Like Villa Ninetta, Maison Valentina is one of those confidential projects reserved for network professionals. Like other new residences in Monaco, this high-end real estate complex outlines a new map of investment opportunities, as well as residential uses. A rare product likely to attract a demanding international clientele seeking security, fiscal stability, and confidentiality.

The impact of these programmes on Monaco’s real estate market in 2025 

These Monegasque projects are redefining the Principality’s premium real estate offering. By now integrating environmental criteria into new-builds, unprecedented services, and locations previously inaccessible, they are imposing a new luxury standard in real estate. The market is becoming more segmented, more exclusive, but also more unpredictable for unassisted investors. Land scarcity structures prices, and the search for yield or resale capital gains becomes a strategic challenge. Today, we speak of sustainable investment in Monaco. In a context where opportunities are rare, mastering access to these programmes becomes a strategic lever, and our services are tailored to match these offerings.

Investing in new-build property in Monaco in 2025: keys to a strategic purchase

A new programme in Monaco is not viewed like an older property. Negotiation, delivery timelines, taxation, off-plan reservation contract (VEFA), signing with a Monegasque notary, resale conditions, builder guarantees: each project has its own rules. Some units are never listed online, accessible only through connections.

Investing in the Principality therefore requires more than a favourite. You need access to market data, an active network, and a solid understanding of Monaco real estate taxation, especially in cases of patrimonial acquisition or medium-term resale. Each residence presents a specific usage typology: optimised main address, luxury pied-à-terre, or property aimed at targeted rental yield. Note that these programmes very often include ecological criteria aligned with the Principality’s ambitions. High-performance glazing, sustainable materials, water and energy management are all initiatives that fit into the environmental policy implemented across the territory. They promote solutions to achieve carbon neutrality by 2050.
