About Us

Monolithe Building

Monolithe SA

Pierre Etoile Promotion group was founded in 2002 and included the brokerage service called Pierre Etoile Courtage. In 2019, the main shareholder decided to hand over responsibilities to the young(er) team in place and Monolithe SA was created to take over this activity. As an independent, forward-looking company, Monolithe is also involved in land search and real estate development. Adrien Bornand, Sarah Amorim, and Julie Zweili lead and manage this entity with professionalism and enthusiasm, displaying an optimistic mindset and a hands-on approach.

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.
