Bouygues Immobilier and Brownfields Acquire 236 Real Estate Assets from Engie
Alongside Brownfields and DMD Invest, Bouygues Immobilier has completed the acquisition of a land portfolio partly derived from the former Gaz de France, comprising 194 hectares of land and 355,000 m² of built space.
A Portfolio of 236 Assets Transferred Through Share Purchase
Brownfields, Bouygues Immobilier and DMD Invest have completed the acquisition from ENGIE of a portfolio of 236 real estate assets distributed across French territory. The portfolio represents approximately 194 hectares of land and 355,000 m² of built space.
These sites, partly stemming from the historical Gaz de France heritage, will be subject, depending on their profile, to urban redevelopment operations, sale following remediation, or continued use. Some of them date back to the early twentieth century and were part of French energy history before being gradually adapted to new uses.
Following a call for tenders, Brownfields was selected as the lead of the consortium comprising Bouygues Immobilier and DMD Invest. The transaction was structured as a share transfer: the assets were contributed to three dedicated companies, with their entire capital being transferred to the consortium.
Each of these companies follows a distinct value creation logic. The first aims at transforming certain sites into mixed urban projects incorporating housing, offices, activities and services, led by Brownfields and Bouygues Immobilier. The second focuses on the progressive valorization of land assets intended to accommodate new uses. The third provides for the retention and management of a rental portfolio of offices and business premises, led by Brownfields and DMD Invest in a long-term asset holding strategy.
A Third Disposal by ENGIE Following 2019 and 2022
For ENGIE, this transaction follows disposals completed in 2019 and 2022 with consortiums also led by Brownfields. The Group presents it as a step in optimizing its historical real estate portfolio in France, which reduces its long-term environmental exposure.
According to Jean-Louis Samson, ENGIE's real estate director, the transaction is part of the Group's refocusing strategy on businesses related to energy transition. It is based on a logic of reusing already artificialized land, intended to limit the consumption of new space.
On Brownfields' side, ENGIE's partner since 2016, the company reports having acquired nearly 500 sites representing more than 700 hectares of land following this transaction. The operator claims negative net land artificialization, having restored 74 hectares to nature.
Bouygues Immobilier had 971 employees at the end of 2025 for revenues of 1.388 billion euros. DMD Invest presents itself as a heritage real estate company, notably known for the E-Valley project involving the redevelopment of the former Cambrai air base.
