Prefab Extension – France

Two-storey prefabricated timber extension between Haut Jura Park and Lake Geneva

In spring 2020, a 200 m² eco-friendly extension was built in Sergy, connecting to the existing home via corridors on both floors. The project combines fast construction with seamless landscape integration in the green heart between Haut Jura Natural Park and Lake Geneva.

Main features:

• 200 m² extension over two storeys
• Timber-frame prefabricated structure
• Functional link to the original house through corridors on each floor
• Dual-pitch roof
• Large glazed openings overlooking the garden
• Natural finishes and clean lines for harmonious landscape integration

Completed in less than a month, the project follows eco-building principles, creating a bright, welcoming living space perfectly blended with nature.
