The building
cadastre and 3D survey- Footprint
- 605 m²
- measured, the ground under the building
- Floor area (estimate)
- ~2,200 m²
- 4 storeys, estimated from the building volume
- Per current company
- ~147 m²
- Box numbers

- 1,350 m²
An association of co-owners (VME) is registered. The building is therefore divided into apartments or units that each have an owner.
The buildings come from the cadastre and the 3D survey (LiDAR), the box numbers from the BEST address register and the heritage from the regional registers. A registration says who is based here, not who owns it.
Registrations and outcomes per year

Recommendations
- Open the dossier of the company you are interested in. The list shows whether it has its registered office here or only an establishment.
Method and limits of this check
A shared address is not suspicious in itself. Office buildings, accountants and business centres host many companies. The verdict is about the kind of address, not about any individual company.
The comparison rests on all 1,408,687 active Belgian addresses. Half of them have one company, 95% at most five, 99% at most ten and 99.9% at most 35.
The list of an address holds the companies in the KBO register and those that left it since April 2026. A company that stopped before then is not in it. So the bankruptcies at this address are shown as counts. The comparison with Belgium runs over the postcode, for the same founding years and after the same number of years. It comes from the survival tables, which start from the founding deeds in the Belgian Official Gazette and count the companies that stopped too.
A shared director holds 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. So the building shows them as estimates, next to the measured footprint. No register of building use (office, housing) is available.
