GPF Introduction


Jean Simonin founded the eponymous estate agency Jean Simonin. The company quickly gained in-depth experience, notably in the management of co-owned properties (propriétés par étages), in accordance with the particularities of real estate in Geneva. Over the decades, Jean Simonin made his company a great success, and it quickly established an excellent reputation in its field. He was joined by his son, Gérard, who took up the reins of the company. In turn, Gérard Simonin maintained the company’s high level of success. Gérard himself then approached prospective buyers in preparation for his retirement.


This was the year when Mr Simonin met Flavio Brisotto and José Exposito. In order to pursue new business interests, while keeping up with the company’s original activities, it was agreed that another legal entity should be created under the name Simonin Partenaire Immobilier SA. This company would add new sectors to its original portfolio: real estate expertise, creation of housing cooperatives and giving owners the possibility of accessing the accounts for their building(s) directly from the comfort of their homes via the internet.


Following Mr Simonin’s decision to withdraw from the business to enjoy his well deserved retirement, and to face the new challenges that will arise in the future, Flavio Brisotto and José Exposito changed the company’s name into:  GPF Gestion de Patrimoine Foncier SA. This company is committed to facing the future by providing new services in the field of real estate management, while maintaining its original expertise and building on a 70-year history.


The acquisition of GPF by m3 IMMOBILIER marks a significant milestone in the company’s history.

This acquisition has allowed GPF to benefit from the expertise and resources of m3 IMMOBILIER, further strengthening GPF’s position in the market and signaling the beginning of a promising new phase.
m3 IMMOBILIER is a key player in the real estate sector in Geneva. The group offers a comprehensive range of services for residential, commercial, and industrial projects, including real estate development and investment, architecture, renovation, sales, and property management. The teams are involved at every stage of the life cycle of a building.
