About Immobilière B2

Real estate is our business. Local expertise is our strength. Human connection is our signature.

Behind B2 is Gaëtan

My name is Gaëtan Lefebvre. I founded Immobilière B2 17 years ago in Lasne.

I chose to create an independent real estate agency. I wanted to offer simpler and more personal support. A single point of contact follows each project, from the first meeting to the signing at the notary's office.

This approach allows me to know each property, as well as its history and that of its owners. For 17 years, I have been assisting families with their real estate projects in Walloon Brabant and Brussels.

Immobilière B2 is an independent real estate agency based in Lasne, specializing in the sale of residential and luxury properties in Lasne, Waterloo, Genval, Rixensart, Braine-l’Alleud, and La Hulpe. The agency also assists clients in Brussels: Etterbeek, Woluwe-Saint-Pierre, Woluwe-Saint-Lambert, and Saint-Gilles…

Local expertise built over time

The real estate market is not limited to national averages.

In Lasne, prices and sales times can vary from one village to another: Ohain, Maransart, Couture-Saint-Germain do not have the same dynamics. The same applies to Waterloo, Genval, Rixensart or La Hulpe, and in the Brussels municipalities we cover.

This knowledge is not learned from a market report. It is built visit after visit, negotiation after negotiation, year after year. It is what allows me to tell you what a property is truly worth, and not just what we would like it to be worth.
