Overlooking the Pays de Gex for more than two millennia, Château de Grilly stands on the foundations of a Roman fort dating back to the 1st century BC. Becoming the ancestral seat of the prestigious Grailly family during the Middle Ages, it has evolved through the centuries while preserving its remarkable architectural character. Carefully restored by its current owner, the château is listed on the Supplementary Inventory of Historic Monuments and today represents an exceptional piece of French heritage.
The estate comprises the château, a caretaker’s house, a garage and an outbuilding. A building permit, included in the sale, authorizes the creation of approximately 800 sqm (8,611 sq ft) of additional gross floor area (GFA), offering outstanding development potential in one of the most sought-after locations on the doorstep of Geneva.
The château currently offers 11 rooms, including 7 bedrooms, arranged over two main floors. The top floor remains entirely convertible, providing numerous possibilities for further expansion or redesign.
This exceptional property is ideally suited as a prestigious private residence, a luxury hospitality project or a high-end investment opportunity, in a highly desirable location just minutes from the Swiss border.
Please do not hesitate to contact me for further information.
