The building

cadastre and 3D survey

Footprint: 354 m²; measured, the ground under the building
Floor area (estimate): ~4,300 m²; 13 storeys, estimated from the building volume

Per current company: ~49 m²
Box numbers: 8
Height: 42.2 metres
Volume: 12,829 m³
Plot: 1,241 m²

An association of co-owners (VME) is registered. The building is therefore divided into apartments or units that each have an owner.

Protected heritage

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.

Insights on this address

Domiciliation address or business centre

87 companies are registered here now, in a building of about 4,300 m² of floor space. That is about 49 m² per company. Most are not tied to one another. So little space per company and so few ties fit a letterbox address or business centre.

This address has more companies than 99.9% of Belgian addresses, which have at most 35.
The address register knows 8 box numbers for this entrance, against 87 registered companies.
49 have their registered office here, 38 only an establishment or branch.
The most common main activity is Activities of lawyers (69101), at 24 of the 53 current companies with a known activity (20 different). Then come Dental practice (86230): 6, Business and other management consultancy (70200): 4.
None of the 65 companies here shares a current director with another.
Half of the current companies have been registered here for less than 17 years.
This address had 4 new registrations in the last twelve months (14 in three years).
5 companies are dissolved or no longer in the register.

Recommendations

For one company at this address, open its dossier and check whether it has an establishment elsewhere. That is most likely where it actually operates.
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.
Look at staff and fixed assets in its annual accounts. They show whether there is real activity behind it.

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.
