"Château de Grilly - Exceptional Heritage, next to Divonne-les-Bains"

In the heart of the Pays de Gex, just a few minutes from Geneva International Airport, Château de Grilly embodies more than two millennia of history. Established on the site of an ancient Roman military fort dating back to 45 BC, the castle and its estate have undergone careful restoration since the 1990s. The castle is partially listed as a historic monument since 1987. However, this protection does not concern the interior spaces, which can be renovated and rearranged according to the wishes and needs of future owners.

The castle develops 518 m² of living space, spread over two levels and two towers, with generous reception areas and seven bedrooms. It preserves precious architectural elements: ancient fireplaces, coffered ceilings, stone staircase, sculpted frames, and traces of its defensive past.

On the top level, a platform of approximately 200 m², located under a remarkable, carefully restored centuries-old timber frame, offers the possibility of arranging up to two additional apartments. Architect's plans are available on request.

The castle's roof has been entirely renovated, particularly in terms of waterproofing and insulation, constituting a major heritage asset. The configuration of the two towers also allows for their conversion into two separate and independent dwellings.

On a plot of 2,019 m² with a courtyard and garden, an independent caretaker's house of 83 m², comprising two bedrooms, offers additional space that can be used for staff or a rental project.

Another major advantage is a granted and purged building permit, allowing the construction of a residential building accommodating four high-end apartments in the location of an old farm. The project, designed in respect of the heritage context, provides approximately 705 m² of floor area and twelve parking spaces.

In total, the estate presents a potential of nine apartments, including the outbuildings, in addition to the main living areas of the castle spread over two levels. The additional renovations planned in the castle do not yet have approved authorizations. However, an architect has already studied these possibilities and can develop the corresponding projects.

This rare property combines an exceptional historical residence, a privileged living environment near the Romandy region, and an already structured real estate development potential. A unique opportunity for a large family or heritage project.

A technical report on the buildings is available on request.
A privileged location in the heart of the Pays de Gex
