cadastre and 3D survey- Footprint
- 287 m²
- measured, the ground under the building
- Floor area (estimate)
- ~1,800 m²

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.

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.
- Look at how the former companies ended. That says something about the address, nothing about any individual company.
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. There is no national reference for bankruptcies and new registrations. So they are shown here as counts.
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.
