Built in 1963 and completed in 1970, Le Schuylkill is Monaco's very first high-rise building. With its 25 levels (18 in the superstructure, 7 in the infrastructure) and a height of 78 metres, it is located in the heart of the Monte-Carlo district. It overlooks a quiet residential area, in the immediate vicinity of the Monte-Carlo Casino, the Metropole Shopping Center, the Le Balmoral and Le Park Palace residences. This tower embodies the architectural heritage of the 1960s while symbolising a visionary orientation towards a controlled densification of the Monegasque territory.

The name "Schuylkill" honors the Pennsylvania River, Princess Grace's hometown. Gildo Pastor, builder of several emblematic buildings in Monaco, wanted from the outset to place the building in a continuity between princely prestige and heritage. Today, the property belongs to Sylvia Ratkowski-Pastor, heiress to the Pastor family group. In a desire to preserve the architectural identity of the building and its role in the historic urban landscape of the Principality, she expressly refused a total reconstruction, choosing a complete renovation in homage to her grandfather.

A daring architectural project entrusted to international references

The complete renovation of the Schuylkill is being carried out by Zaha Hadid Architects, winner of the Pritzker Prize and author of emblematic projects such as the Heydar Aliyev Center or the London Aquatics Center. ZHA signs all the interiors, from studios to five-room apartments, with a homogeneous finish, and offers penthouses decorated in a way specific to their typology. Contemporary architecture introduces fluid facades and advanced technical solutions. In charge of the local adaptation, the Monegasque architect François Lallemand presented the project during "50 Minutes Inside" on TF1 on 7 June 2025, alongside Eugenia Petrini and Paolo Petrini, founders of Petrini Exclusive Real Estate Monaco, strengthening the media visibility of the programme.

This project is one of the first to transform a mixed-use building into a totally residential building in Monaco. This is a first in such a small territory. Indeed, the area of Monaco is only 2.08 km², making it the second smallest state in the world. In this context, every square metre becomes strategic, and this type of rehabilitation represents a sustainable solution to the impossibility of expanding the territory.

An exclusively residential programme, adapted to Monegasque demand

The distribution of the 142 apartments reflects a desire to adapt the offer to the diversity of the Principality's residents, with a balance between compact housing and large family areas. All the accommodations are designed with an open kitchen, integrated into the living room, to optimize space and enhance conviviality.

• 26 studios (1 room): a unique space combining living room, sleeping area and open kitchen. Ideal for second homes or rentals.

• 49 two-room apartments (T2): one bedroom, a living room with open kitchen, one bathroom. Typology adapted to young couples or working people.

• 37 three-room apartments (T3): two bedrooms, a living room with open kitchen, two bathrooms. Comfortable for a family with a child or two.

• 24 four-room apartments (T4): three bedrooms, a living room with open kitchen, two bathrooms. Standard family typology in Monaco.

• 2 four-room duplexes : three bedrooms, a living room with open kitchen, two levels for more independence between night and day spaces.

• 2 five-room apartments (T5): four bedrooms, a spacious living room with open kitchen, three or more bathrooms. Rare in Monaco.

• 1 five-room duplex : four bedrooms, a large living room with open kitchen, two levels, with panoramic views.

• 1 six-room duplex (T6): five bedrooms, a reception room with open kitchen, several bathrooms, plenty of storage space. It is the largest and most prestigious accommodation in the program.

Each home benefits from top-of-the-range finishes: natural stone or solid wood floors, reinforced sound and thermal insulation, aluminium joinery with thermal break, Design-Line taps, custom-fitted kitchens. The whole complies with the PMR standard, including large lifts and adapted sanitary facilities.

Residents enjoy premium common areas: a clubhouse (reception and relaxation area reserved for residents), a gym, a spa with indoor pool, a convivial lounge, a common laundry room for washing linens, and an American-style ice machine – an exclusivity that was brought up during the pract.esentation by Petrini Monaco. Two hanging gardens on the 16th and 17th floors will be rehabilitated with a rich plant substrate, ensuring the sustainability and aesthetics of the greening.

Exemplary technical and environmental performance

Aiming for BD2M certification at the Augmented Silver level and respecting the objectives of the RIBA Climate Challenge 2030 (623 kg CO₂e/m²), the project includes remarkable performances:

• Usable area increased from 32,000 to 41,000 m² (+28%)
• 153 light vehicle spaces
• 16 m² for two-wheelers
• 192 cellars in the basement
• Partial conservation of the structure (concrete, floors)
• Ventilated ceramic facades, reinforced insulation
• XCarb® low-carbon steel for reconstituted elements
• Connection to the thalassothermal loop for heating and air conditioning
• Wastewater recovery system
• Partial reuse of demolition materials

The approach is part of the circular economy: conservation of existing structures, reuse of materials, construction sites with reduced nuisances (controlled dust, traffic plan, noise limitation).

A controlled site, deliveries in phases from 2026

The project, which began in early 2024 after six years of preparation, is divided into several phases: interior cleaning, seismic reinforcement, installation of a transfer slab in the 14th arrondissement, demolition of levels 15 to 17, reconstruction, cladding of the facades, interior fittings and finishes. No additional floors were added, unlike the first initial plans. The building will be delivered in three blocks (A, B and C) from 2026. The final delivery of the complex is scheduled for July 2027. The Schuylkill is designed as a residential rental building; Only ten privately owned apartments will be marketed, accessible to ultra-privileged profiles ready to invest well above market prices.

Approved by the Municipal Council almost unanimously (one abstention), the project is part of Monaco's strategy for sustainable and qualitative urban planning. It complements operations like Mareterra by favoring rehabilitation instead of expansion. This model became a reference for the future of the transformation of Monegasque buildings.
