Léon Tombulaan 4
Building with many business tenants
19 companies are registered here now, more than at 99% of Belgian addresses, in a building of about 520 m² of floor space: about 27 m² per company, room enough for an office each. Most are not tied to one another: independent tenants of one building.
- More companies than at 99% of Belgian addresses (which have at most ten).
- 9 have their registered office here, 10 only an establishment or branch.
- Most common main activity: General medical practice (86210), at 5 of the 9 current companies with a known activity (5 different). Then Business and other management consultancy (70200): 1, Office administrative and support services (82100): 1.
- None of the 12 companies here shares a current director with another.
- Half of the current companies have been registered here for less than 14 years.
- 3 new registrations in the last twelve months (5 in three years).
What you can do with this
- Open the dossier of the company you are interested in: the list shows whether it has its registered office here or only an establishment.
- Look at how the former companies ended: that says something about the address, nothing about any individual company.

What this check does and does not say
A shared address is not suspicious in itself: office buildings, accountants and business centres host many companies. The verdict says what kind of address this is, nothing about any individual company.
The comparison rests on all 1,408,687 active Belgian addresses: half have one company, 95% at most five, 99% at most ten, 99.9% at most 35. There is no national reference for bankruptcies and arrivals; they are shown here as counts.
A shared director is a current board mandate at two companies at this address; statutory auditors and liquidators do not count.
Floor area and storeys are not measured anywhere: the building shows them as estimates, next to the measured footprint. No register of building use (office, housing) is available.
