Description
A few minutes by bike from the center of Onex and ten minutes from Les Acacias, discreetly reveals one of those properties that the market hardly ever sees.
Built between 1835 and 1838, and listed in Geneva's inventory of buildings worthy of protection, this mansion unfurls 397 sq. m. of living space - 512 sq. m. of usable area - on an exceptional 3,034 sq. m. plot, entirely enclosed, bordered by a private forest that gives it absolute privacy and a calm rare this close to the center. The house is currently undergoing a complete renovation, now well underway.
The house
The first floor features a bright entrance hall served by a spiral staircase, a large kitchen of over 19 m² with fireplace, a 25 m² dining room also with fireplace, and a generous 34 m² living room. A guest toilet completes this level.
On the second floor, four bedrooms - including a 30 m² master bedroom with 23 m² en suite bathroom and its own fireplace - offer generous ceiling heights, period moldings and windows bathed in natural light. Each bedroom benefits from its own private bathroom.
The second floor, converted into an independent master suite, has an additional bathroom accessible from the hallway.
The basement, accessible from inside and out, houses a massive stone wine press that can be used as a carnotzet table, complemented by a utility room and laundry room.
The greenhouse
Edified in 1860, this greenhouse of almost 46 m² is one of the few from this era still standing in Onex. Entirely glazed and south-facing, it offers remarkable luminosity in all seasons and lends itself to multiple uses: reception space, resting place or independent studio. The exterior envelope is protected and cannot be modified.
Exteriors
The 3,034 m² plot, listed as a historic park and garden in Switzerland, is fully enclosed and secured by a large electric gate. A driveway leads to the house and its large wooden terrace, followed by a 40 m² swimming pool and a 35 m² garage with two covered parking spaces. The rest of the plot, planted with park-like trees, offers several additional parking spaces. The private forest, unique to Onex, occupies a third of the plot and provides incomparable calm, cachet and privacy.
