A rare opportunity combining historic heritage with approved real estate development potential, with no further planning procedures required.
In the heart of the charming village of Grilly, just minutes from Geneva and its international airport, this remarkable listed château, protected as a Historic Monument, has benefited from a high-quality restoration and enjoys an exceptional heritage setting.
The property currently offers approximately 518 sq.m of living space arranged over two levels, complemented by more than 200 sq.m of additional convertible space on the top floor and in the attic, as well as an independent caretaker’s house.
A key asset of this unique estate in the Pays de Gex is the granted building permit for the construction of an elegant residential building designed to recreate the estate’s former historic farmhouse, which disappeared several years ago. Designed by a French architect in close collaboration with the French Heritage Authorities (*Architectes des Bâtiments de France*), the project fully respects the site's architectural and historical identity.
The approved development provides for the creation of four exceptional apartments, each occupying an entire floor and benefiting from generous living areas:
* Garden level: 4-room apartment of 139.86 sq.m with private garden
* First floor: 5-room apartment of 204.60 sq.m with terrace
* Second floor: 5-room apartment of 196.33 sq.m with terrace
* Attic level: 3-room apartment of 118.55 sq.m with terrace
Each residence will benefit from private cellars, storage facilities, dedicated parking spaces, and a shared bicycle storage room.
The completed architectural ensemble will create a harmonious estate where heritage and contemporary living meet with elegance. The Roman tower, remarkable roofs, chimneys, staircases, and listed historical features give the property a rare and authentic character.
This unique property offers several possibilities: a prestigious private residence, a heritage enhancement project, or a high-end residential development in one of the most sought-after locations in the Pays de Gex.
An exceptional opportunity for lovers of historic properties, discerning investors, and heritage enthusiasts wishing to bring an ambitious real estate project to life in a setting steeped in history.
The granted building permit and the extensive studies already completed provide developers and investors with an immediately actionable project, offering significant time savings on both administrative and heritage approval processes.
