The building
cadastre and 3D survey- Footprint
- 78 m²
- measured, the ground under the building
- Floor area (estimate)
- ~400 m²
- 6 storeys, estimated from the building volume
- Per current company
- ~6 m²
- Height
- 19.6 metres
- Volume
- 1,194 m³
- Plot
- 78 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
Domiciliation address or business centre
67 companies are registered here now, in a building of about 400 m² of floor space. That is about 6 m² per company, too little for an office each. Most are not tied to one another. That fits a letterbox address or business centre.
- This address has more companies than 99.9% of Belgian addresses, which have at most 35.
- 54 have their registered office here, 13 only an establishment or branch.
- None of the 59 companies here shares a current director with another.
- Half of the current companies have been registered here for less than 3.8 years.
- This address had 6 new registrations in the last twelve months (30 in three years).
- 1 company went bankrupt while registered here.
- Of the companies founded from 2018 to 2020 with their seat in postcode 1000, 7.1% went bankrupt within five years. For Belgium as a whole that is 6.5%.Survival tables
- 1 company is dissolved or no longer in the register. 2 others moved away and still exist.
Recommendations
- Ask the company where it works and who receives its mail. A registered office in a business centre is allowed and is not a bad sign in itself.
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.
