Monaco Mareterra - Why Is It Considered the Most Expensive Real Estate in the World ?

What is Mareterra and Why Does It Attract Global Attention in Luxury Real Estate ?

Mareterra is a new eco-district built on six hectares reclaimed from the Mediterranean Sea, southeast of Larvotto in Monaco. This project combines territorial expansion, urban design, and residential luxury, creating an environment that blends high-end residences, seaside promenades, shops, and public green spaces.

This development attracts international attention because it represents both a major technical achievement and a response to global demand for rare and prestigious properties. Its unique positioning in terms of location, architecture, and ecology makes Mareterra a symbol of ultra-luxury and sustainable real estate.

Why Has Mareterra Become the Most Expensive Real Estate Project in the World?

Mareterra stands out for its very high prices per sqm, with sales around or exceeding €100,000 per sqm, sometimes reaching €120,000 or more for the most prestigious units.

This valuation is explained by several factors:

• Land scarcity — Monaco is one of the most densely populated territories, and any additional land immediately increases in value.
• Renowned international architects — prestigious signatures enhance both appeal and global recognition.
• High-end amenities and exceptional sea views — all residences offer unique finishes and panoramas.
• Eco-design and urban innovation — the combination of luxury and sustainable design adds a new dimension to perceived value.

These elements make Mareterra a highly sought-after asset for ultra-wealthy international clients.
