In 2007, Sandrine and Olivier Kretz decided to create an agency
specializing in luxury real estate.
They wanted this agency to be a reflection of their personalities: to be resolutely independent,
human, agile, and for it to feel like a family.
Above all, they want to share more than real estate. They want to share
life projects,emotions, dreams, and a whole art of living.
It was therefore quite natural that three of their sons,
Martin, Valentin, and Louis, joined them in their 1930s
office-home in Boulogne Billancourt to continue to invent, as a family,
this new way of doing real estate.

A family with a unique network in France and abroad
We work with independent local teams who share our values. These men and women understand that the human element is at the heart of their business.
They love the regions where they work - they know them well because they live there.
At KRETZ they feel at home.
Each agent is sponsored by a family member.
They have access to KRETZ's qualified database, they benefit from all the innovative tools and our original material to communicate and promote our properties.
Together, we form a professional team united by expertise and values. At the same time, our individual independence allows us to be agile and proactive.

State-of-the-art technology

What's important for us is to provide memorable experiences. We are constantly looking for the most efficient and innovative tools to enhance your property and tell a unique story. Thanks to cinemagraphs, drones, Osmo cameras and the help of image professionals, we capture the soul of each property and invite you inside.


Join us to discover unforgettable homes. Open the doors of a family cottage, push the gates of a castle or those of a dream villa.
Take a moment to sit on the terrace and contemplate the sea or the mountains.
Imagine living in a loft above the rooftops of Paris or having lunch in the shade of a secluded secret garden. Each of our dream destination properties is an encounter, the promise of a life adventure.
