Our expertise
De nombreux atouts à votre service
We have accumulated 40 years of experience in real estate in Geneva, a field that we are passionate about but which is becoming increasingly complex. We have thus acquired an expertise that serves you advantageously at every stage of our journey together.
With Adrien Désormière and Sandra Vanhalst, you benefit from a privileged relationship. We prioritize quality over quantity. We prefer to handle few cases at a time, so we can invest ourselves without constraint until success is achieved. And we keep you regularly informed of the results of our activity.

Une palette de services « à la carte »: c'est vous qui choisissez
Our services form a complete range, and you are free to mandate us “à la carte”, for all the services offered, or for only a part, as a:
- private owner: from valuation to the brokerage mandate
- developer: from the project study to the off-plan sales mandate, including property enhancement and commercial management.
- buyer or tenant client: search mandate
Reposez-vous sur nous: nous prenons les choses en main
When you entrust us with a mandate, we take care of everything from A to Z: from the signing of the mandate you entrust to us until the handover of the keys.
The clients with whom we visit your property are qualified clients, and we have ensured beforehand that your property meets their expectations in order to avoid any unnecessary back-and-forth.
We organize ourselves according to your availability so that visits disrupt your daily life as little as possible.


Nous sommes à la pointe de l'innovation
You benefit from the latest technological innovations in the fields of:
- communication.
- The latest technological tools hold no secrets for us and we implement them to enhance the value of your property: drone views, videos, virtual tours, virtual home staging…
- Today, it is essential to be visible on social networks and we master this communication channel: your property will be highlighted and proposed to a panel of clients selected according to criteria precisely defined by us.
- Do you like a property? Save it and find it at any time in your private portfolio by registering on our portal.
- market analysis: we are developing a computer tool that uses artificial intelligence to analyze the market and provide you with statistical and factual data, complementing our personal knowledge of the field.
Préservons l’environnement
We are also sensitive to the environment in which we and our clients operate. We wish, at our level, to contribute to a better world.
To fight against global warming, we plant 2 trees for every sale we complete. This choice is also a nod to our logo. We also sponsor a beehive to preserve biodiversity. Follow this link to learn more about our approach.
Always with an ecological concern, we process a maximum of data in digital format to avoid unnecessary printing of files.


Vous êtes notre priorité
Our motivation is to achieve the satisfaction of our clients, whom we have the pleasure of seeing again after the transaction.
We have a passion for our profession and for harmonious, high-quality relationships.
