About Us

Monolithe Building

Monolithe SA

Founded in 2002, the Pierre Etoile Promotion group included among its divisions a brokerage service named Pierre Etoile Courtage. In 2019, when the principal shareholder decided to pass on their responsibilities to the existing young team, Monolithe SA was established to take over this operation. As an independent company firmly oriented towards the future, Monolithe is also actively involved in land acquisition and real estate development.

In addition to brokerage activities, we are also active in the research of plots and the provision of services and sales forces on behalf of third parties, using new brokerage techniques and market approaches.

Our entity is now headed by Adrien Bornand, Sarah Hundemer and Julie Zweili, a new generation projecting the family experience into a new vision of real estate.
