Between Carouge and the foot of the Salève, Troinex marries a historic village with sought-after residential neighbourhoods.
The commune attracts families with its quiet villa areas and its school at the heart of the village. Detached houses dominate the market, complemented by small recent co-ownerships around the place de la Mairie.
The closeness of Carouge and quick access to the Pierre-Grand border crossing support steady demand. Properties with a view of the Salève or a well-oriented garden hold their value best.
