Building Energy Renovation, Barn Conversion, New Multi-Generation House & Geothermal System

This French public works tender, published on March 11, 2026, requires a contractor to undertake a multifaceted construction project involving both renovation and new build elements. The project centers around improving the energy efficiency of existing structures alongside constructing new residential capacity. Specifically, the work includes energy upgrades to existing buildings, conversion of an existing barn into a habitable dwelling, and the construction of a new multi-generational house. A critical component of the project is the installation of a geothermal heat pump system, including the associated heating network, suggesting a focus on sustainable energy solutions.

The project's complexity stems from the combination of different construction types: renovation, conversion, and new construction. The integration of a geothermal system adds another layer of technical expertise required. While the exact scale is unknown, the description implies a significant undertaking, especially considering the multi-generational house component and the regional scope within Auvergne-Rhone-Alpes. The deadline for submissions is April 17, 2026. Contractors should carefully assess their expertise in these specific areas, particularly geothermal energy systems, to determine their suitability for this tender.

Given the mix of renovation, conversion, and new build construction, as well as the integrated geothermal system, potential bidders should consider factors such as regional regulations and building codes for energy efficiency and geothermal installations. Further investigation into the specific requirements and details of the tender is crucial before committing to a bid. Due to the absence of specific information on the location (city) and the missing CPV codes, accurately targeting the required expertise might prove difficult.
