Insights on this address

Building with many business tenants

98 companies are registered here now. They are based in a building of about 10,700 m² of floor space. That is about 109 m² per company, room enough for an office each. Most are not tied to one another and rent independently in the same building. They are tied as follows: 5 in the Emeria Benelux group, 5 named European, 5 named Seco and 3 named Arthur.

  • This address has more companies than 99.9% of Belgian addresses, which have at most 35.
  • 58 have their registered office here, 40 only an establishment or branch.
  • None of the 74 companies here shares a current director with another.
  • Half of the current companies have been registered here for less than 8.7 years.
  • This address had 3 new registrations in the last twelve months (13 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
  • 2 companies are dissolved or no longer in the register. 1 other moved away and still exists.

Recommendations

  1. Open the dossier of the company you are interested in. The list shows whether it has its registered office here or only an establishment.
  2. 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.
