The building
cadastre and 3D survey- Footprint
- 338 m²
- measured, the ground under the building
- Floor area (estimate)
- ~400 m²
- 1 storey, estimated from the building volume
- Per current company
- ~57 m²
- Height
- 5.9 metres
- Volume
- 1,207 m³
- Plot
- 2,693 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.
Registrations and outcomes per year
Shared address
7 companies are registered here now. The building has about 400 m² of floor space, about 57 m² per company.
- This address has more companies than 95% of Belgian addresses, which have at most five.
- 6 have their registered office here, 1 only an establishment or branch.
- None of the 7 companies here shares a current director with another.
- Half of the current companies have been registered here for less than 4.1 years.
- 1 company is dissolved or no longer in the register.
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.
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.
