Le Renzo at a glance
Le Renzo is the main residential building of Mareterra, the new district of Monaco built on land reclaimed from the sea at Anse du Portier. Designed by the Renzo Piano Building Workshop, it stands at the western end of the district, above the Port du Petit Portier and the central square of Mareterra.
All the apartments of the Mareterra programme sold off-plan, before delivery. Today, apartments at Le Renzo change hands as resales, often through private networks and off-market introductions.
The architecture of Le Renzo
Renzo Piano, the Genoese architect behind the Centre Pompidou in Paris and The Shard in London, designed Le Renzo as a long building with a silhouette inspired by a ship, a reference to the maritime history of Monaco.
- On pilotis: the building rests about five metres above the ground, which preserves the sea view from the older waterfront and frees the ground level for a public promenade, shops and restaurants
- Façade: white marine aluminium cladding, with balconies facing the horizon and vertical balancing bars
- Glazing: large windows that bring natural light into the apartments and frame the sea
- Environment: sustainable construction principles, as part of the first national eco-district of Monaco
The elevation of the building stands out among the residences of the Principality: from the promenade, you walk beneath Le Renzo towards the sea.
The design answers a constraint of the site. Monaco has little land, so the district gains its space from the sea, and the architect lifted the building to keep the ground level open. For an owner, this choice has practical effects: the apartments sit above the promenade, away from the street-level movement, and the long façade gives many rooms an orientation towards the sea.
Apartments and prices at Le Renzo
Apartment sizes and layouts
Le Renzo focuses on very large apartments, rare in Monaco, where the average apartment remains compact. The majority of units exceed 400 m², some occupy full floors, and the top of the building hosts a penthouse on four levels.

- Layout: 3 bedroom suites, 3 bathrooms, guest and staff powder rooms, two walk-in closets in the main suite

Price levels
Prices at Le Renzo stand at a level of their own in Monaco. Market sources quote about €100,000 to €120,000 per m² for Mareterra, roughly double the Monaco average of €57,569 per m² measured by IMSEE in 2025. Sales of new property carry 20% VAT.
Prices per m² come from our own calculation. The penthouse acquisition, finalised in 2024 according to registry records reviewed by Bloomberg, ranks among the residential transactions of record value reported worldwide; the buyer's holding company confirmed the purchase but not the price.
