Your trust makes us what we are: "your privileged real estate advisers"...

With more than 10 years of experience in real estate in Brussels and Brabant, TRIANON INVEST IMMOBILIERE is a professional real estate agency in buying, selling, renting and managing properties.

TRIANON INVEST IMMOBILIERE is much more than a Brussels estate agency... When you call on us, you can be sure of benefiting from : 


  • 93% File conversion rate
  • 45 to 60 d Average selling time
  • 5% Average delta between the estimate and the sale price
  • 96% Customer satisfaction rate


TRIANON INVEST IMMOBILIERE's estate experts will do their utmost to guarantee you a result that meets your expectations in the shortest possible time. Even in delicate situations (separation, divorce, joint ownership, inheritance), we will accompany you to the desired result.

Our agents will advise and support you in all discretion. They will go into the details with you to serve you most effectively afterwards. At your side, we carry out the essential tasks that allow you to sell or rent your property serenely and efficiently (single-family house, investment property, mixed-use building, flat, loft, studio, workshop, garage, etc.).

Reactivity, dynamism and efficiency are the keys to our common success.
Don't wait any longer, contact our agencies.


Throughout our collaboration, our agents are at your disposal to meet your expectations and advise you on legal obligations, financing, negotiations, etc. They listen to the objectives you set and implement them. 

We take care of the administrative formalities and we will help you with the administrative procedures so that you too can master the issues at stake:

  • Legal obligations: obtaining PEB certificates and electrical certificates (inspection reports), issuing town planning certificates (via the municipality), notarial procedures, etc.
  • Financing: mortgage registration, banker's order, release, management of the bridge loan, suspensive clause for obtaining a loan, etc.
  • Negotiation: swift deed of sale, unconditional signature of a compromise, extended enjoyment of your property, current rental lease, etc.

Each property has its own specificities, each owner has its own requirements: 


In order to be closer to its clients and to better support them, TRIANON INVEST IMMOBILIERE has opened a second office in the town of Uccle, on the prestigious Avenue de la Floride. New employees have taken up residence in this 140m² multi-purpose space with a car park to welcome you.

In the meantime, the new Anderlechtois shop window has been opened at 31 Potaerdenberg Street, and it is with great pleasure that we will now also welcome you there.

TRIANON INVEST IMMOBILIERE's historical approach, which was instilled by its director, Mr. Obri Alexis, has not changed: listening to you and advising you. Now more than eight employees pursue the same objective on a daily basis.

TRIANON INVEST IMMOBILIERE is a complementary team that discusses the challenges of your real estate projects in all the municipalities of Brussels and its suburbs on a daily basis.
