Description
A historical gem in the heart of Geneva Champagne
Located in the charming village of Laconnex, this emblematic castle embodies elegance and prestige. Its origins date back to the 15th century, when it served as a stronghouse for the noble family of Laconnex. Rebuilt after the 1536 fire, it retains its authentic character, marked by centuries of history and refined transformations
Built on four levels, the castle today offers two distinct dwellings, but its potential is considerable: it can become a sumptuous family home or be divided into several lots for a high-end residential project. A buildable land completes this property, offering promoters a rare opportunity to create additional units or a harmonious ensemble in the heart of the village.
Although requiring a complete renovation with a substantial budget, this property represents a unique opportunity on the Geneva market: combining historical heritage and real estate development in a green setting, just a few minutes from Geneva.
An exclusive investment for character enthusiasts and professionals seeking valorization.
