Which new real estate developments will reshape Monaco in 2025?

Monaco never slows down. No sooner is one project completed than another begins. In this tiny territory where prices per square meter reach sky-high levels, real estate continually redefines the industry. Buying property in Monaco—whether a primary residence, holiday home or rental investment—is today a patrimonial strategy. These residences, far more than large-scale operations, redefine the contours of luxury and strategic investment. Mareterra, Bay House, Villa Ninetta, Le Lido or Maison Valentina: a look at Monaco’s new real estate developments and their implications for the market’s evolution.

New developments in Monaco: the projects shaping 2025

The launch of new residential developments in Monaco serves a dual logic: enriching the ultra‑high‑end residential offering and providing investors with rare products with strong resale and profitability potential under an attractive fiscal regime.

Latest new real estate: Mareterra leads the way

Six hectares reclaimed from the Mediterranean. A whole turnkey district delivered in the Principality. Mareterra is not so much a real estate venture as an extension of Monaco. It made headlines months in advance because the scale seemed surreal. Inaugurated on December 4, 2024 by the Princely Family, it embodies a vision laid out from the start by Prince Albert II: to create a place that is both ecologically exemplary and consistent with the Monegasque DNA. Neither a pastiche nor disruption, but a natural extension of the coastline. The project successfully blends urban planning, ecology and an exceptional living environment. As Monaco’s first eco‑district, it was conceived as a manifesto. Beyond its architectural and environmental ambitions, Mareterra represents an unprecedented patrimonial asset for any investor seeking to secure an investment in a highly tense land market. Engineered from the start to meet High Environmental Quality standards, Mareterra delivers on both 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% reuse of rainwater;
• 80% of heating and cooling powered by renewables;
• 600 m of cycle lanes;
• 19 000 m² of pedestrian zones;
• 27 000 m² of planted area, including a pine grove of nearly 800 trees.

The calibre of design matches the ambitions: Denis Valode, Renzo Piano, Michel Desvigne—these names weren’t just invited to sign, but to conceive a sustainable and coherent neighbourhood. Mareterra includes:

• 110 apartments;
• 10 ultra‑luxury villas;
• 4 townhouses;
• a marina with 16 berths.

Bay House: a prestigious new residence in Monaco

Located near the Anse du Portier, Bay House is one of the most iconic new residences in Monaco. Part of the wider Testimonio II development, this architectural flagship represents the new face of Monegasque luxury:

• 56 high‑end apartments;
• 5 rooftop villas with garden terraces;
• 3 to 6 bedrooms per residence.

Its lines evoke the waves of the Mediterranean, its balconies embrace the sea. The complex rises just steps from Larvotto Beach. Interiors are high‑end, custom‑made by artisans using Emperador Light marble, White Alabaster, walnut and light woods.

Residents can also enjoy 500 m² of dedicated amenities: spa, massage room, hammam, hair salon, relaxation lounge… everything precisely crafted. It is one of the most accomplished new residences in Monaco in combining quality of life with real estate value. Investors and families alike are drawn, especially with the new international school just meters away.

Testimonio II: integrated residence with school and services

Testimonio II is the vision of Groupe Marzocco and VINCI Immobilier. Inside, designs by Arquitectonica, Alexandre Giraldi and Laura Sessa create a dreamlike environment. With its 378 state‑owned high‑end apartments suspended above Monaco Bay and two towers of 30 and 32 floors reaching 100 m and 110 m, the scale is dizzying. Launched in Q2 2017, the project took seven years to complete. A 50‑place nursery and the new international school are located within. These projects contribute to the emergence of a premium real estate offering in Monaco, characterised by increasing demand for comfort, services and sustainability.

Villa Lucia: refreshing Les Moneghetti

Expected in 2026, Villa Lucia is one of the exceptional new residences enhancing Monaco's landscape. Designed by Alexandre Giraldi—known also for his collaboration with Lord Norman Foster on the Yacht Club of Monaco—the building includes 14 floors with 14 apartments where privacy meets ultra‑luxury. Atop it, a quadruplex with private rooftop pool crowns the building.

Villa Ninetta: a discreet address revitalising Jardin Exotique

From studios to three‑rooms, Villa Ninetta’s 27 apartments bring understated yet refined elegance at the foot of Jardin Exotique. Built on the former site of the Palais Ninetta, this new residence blends local architectural heritage with modern comfort and sustainability—designed by Monegasque architect Fabrice Notari.

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

Real estate agents see it as a forward‑looking project. Situated on Rue des Lilas on the former sites of the “Le Lido” and “Les Hirondelles” villas, Le Lido respects architectural heritage while projecting into the future. Eleven floors, 20 luxury apartments, three parking levels, commercial spaces, residential services and premium amenities. Its location offers enormous advantages—near Millefiori, Buckingham Palace and Monaco’s main attractions.

La Condamine reinvents with Maison Valentina

Maison Valentina emphasises design and environmental integration. Condamine is experiencing a revival. This project, scheduled for delivery in 2026, is ideally located at the foot of the Rock, near the Monaco underground station entrance and the famous Place d’Armes market. Like Villa Ninetta, Maison Valentina is a confidential, off‑market high‑end residence—rare product attracting discerning foreign clientele seeking security, fiscal stability and confidentiality.

The impact of these developments on Monaco real estate in 2025

These Monaco projects redefine the premium real estate offering. By integrating environmental criteria, unique services and previously inaccessible locations, they set a new standard of luxury in real estate. The market becomes more segmented, exclusive and volatile for unaccompanied investors. Land scarcity structures prices, and yield or capital gain potential becomes a strategic issue. Today we speak of sustainable investment in Monaco. Access to these programs becomes a strategic lever—and our services match the scale of these offerings. Discover Monaco’s iconic residences.

Investing in new real estate in Monaco in 2025: keys to a strategic purchase

A new development in Monaco isn’t visited like an old property. Negotiation, delivery schedules, taxation, reservation contracts in VEFA, notarial signature in Monaco, resale conditions, builder guarantees: each project has its own rules. Some lots are never listed online, accessible only through connections.

Investing in the Principality requires more than passion. You need market data, an active network, and a solid grasp of Monaco’s real estate taxation—especially for patrimonial acquisition or mid-term resale. Each residence presents a specific use case: optimized primary residence, luxury pied-à-terre, or targeted rental yield product. Note that these developments often include ecological standards aligned with the Principality’s ambitions—high-performance glazing, sustainable materials, water and energy management—part of the carbon-neutrality policy by 2050.
