Monaco’s Bel Air housing development has entered yet another chapter of delay, with officials now confirming that the three-tower complex will not be fully completed until 2028, several years later than originally envisaged.
The project, located above the new Princess Grace Hospital between Boulevard du Jardin Exotique and the upper reaches of the city, was initially expected to be delivered in 2023. That deadline was later pushed to 2026 and has now been reset once more following the identification of a structural weakness in the ground beneath the site.
Speaking during parliamentary budget discussions, Government Minister for Public Works, Environment and Urban Development Céline Caron-Dagioni revealed that a fracture in the soil was discovered during construction. The finding prompted engineers to redesign the foundations and significantly increase the number of support piles, triggering a substantial knock-on effect on the overall schedule.
Despite efforts to limit the impact, the development will now be handed over in phases rather than as a single completed project. The first stage, due by the end of 2027, will include the base infrastructure—such as parking facilities, a laundry area, a childcare centre and office space—along with Tower C, which will house 55 apartments. Administrative handover to the State is expected shortly afterwards, in early 2028.
The remaining two residential buildings will follow later that year. Tower B, comprising 44 homes, is scheduled for completion in mid-2028, while Tower A, also with 44 units, is expected to be delivered towards the end of the year.
Once finished, Bel Air will provide 143 new apartments, a significant addition in a country where buildable land is scarce and construction timelines are increasingly shaped by technical constraints rather than architectural ambition.
