In Belgium, buildings have a unique way of numbering their floors. “Level 0” is the ground floor, distinct from countries that start with “1” for the ground floor. After “level 0,” you’ll find “1,” “2,” and so on.

Now, about “level -1.” It’s what you’d expect – the basement or an underground floor. Basements in Belgium serve various purposes, from storage to parking, and even living spaces. So, when you see “level -1,” you’re heading below ground.


This numbering system adds a unique touch to Belgium’s architecture, reflecting the country’s distinctive cultural identity and making every building an intriguing discovery for visitors.
