About Bassac
Bassac is a French real estate group listed on Euronext Paris under ISIN FR0004023208 and ticker BASS. Historically known as Les Nouveaux Constructeurs, the company was founded in 1972 by Olivier Mitterrand. In 2020, the group adopted the Bassac name following a legal reorganization, while keeping its stock market listing. Its headquarters are in Boulogne-Billancourt, France.
Bassac’s core business is residential property development and commercial real estate development. The group operates mainly through majority stakes in specialized subsidiaries, which gives it exposure to several markets and business models. In France, it relies in particular on Les Nouveaux Constructeurs and Marignan for residential development and partnership-based projects. Outside France, the group is active in Spain through Premier, in Germany through Concept Bau, and in Belgium through Maisons Baijot. Bassac also owns ZAPF, a German manufacturer of prefabricated garages, as well as complementary activities such as Kwerk in coworking and Main Street.

This operational mix makes Bassac broader than a traditional residential developer. It covers collective housing, single-family homes, office real estate and certain ancillary real-estate-related businesses. The group highlights its ability to create value through land development, control over the production chain, and a portfolio of operating participations spread across several European countries.
From a historical standpoint, Bassac emphasizes its long track record in the property sector, with tens of thousands of homes and apartments delivered since inception. Recent financial disclosures show a presence in France, Spain, Germany and Belgium, as well as visibility supported by a meaningful order book and land bank. In 2024, the group posted revenue of EUR 1.404 billion, up 8%, with stronger reservations and a larger land bank. Bassac therefore stands out as a sizeable European real estate player, with family ownership roots, a holding-company structure, and a diversified positioning across residential and commercial property development.
