Keizerslaan 4
Building with many business tenants
26 companies are registered here now, more than at 99% of Belgian addresses, in a building of about 122,700 m² of floor space: about 4,721 m² per company, room enough for an office each. Most are not tied to one another: independent tenants of one building. Tied by: 6 named Centre, 3 named Association, 3 named Société.
- More companies than at 99% of Belgian addresses (which have at most ten).
- 26 have their registered office here, 0 only an establishment or branch. A registered office is the legal address; where work happens is registered as an establishment.

- Half of the current companies have been registered here for less than 53 years.
- 2 companies are dissolved or no longer in the register.

Companies at this address
26 in totalWhat 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. A sole trader is listed here without a name.
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.
