In an apartment building, the entrance area partly determines how mail is delivered. The standards of bpost and the agreements within the property management or the design team then determine the location, the dimensions and the layout. The WALL modular is designed to follow those rules without compromising on architecture.
bpost publishes guidelines for letterboxes, including for multi-occupancy buildings. These cover accessibility for the postal worker, the height at which a letterbox is mounted and the clearance around it. You can find the exact, current figures at bpost itself or through your building manager. What is certain: a letterbox must be easy to use, without steps or obstacles, and the flap must open smoothly.
For apartments there is an extra layer. Every residential unit is entitled to its own, identifiable letterbox, and the whole must remain clear for the postal worker. A letterbox block that groups the units logically works better in practice than separate boxes side by side.
In practice, mandatory dimensions exist as guidelines, not as one fixed size for every building. The building manager or architect aligns them with the entrance hall, the mail flow and the models used. For that approach there is the WALL modular, a system that is built up per residential unit.
The WALL modular is a wall-mounted model that you assemble per module. This creates a letterbox block that fits exactly with the number of residential units, without leftover space or forced filling. In a renovation or with an extra unit you extend the block in the same design language.
The material is aluminium, which keeps the whole light and easy to maintain. For the finish there are more than 2000 RAL colours, so the block can disappear into a concrete wall or become an accent in the entrance area. You align that colour choice with the architect or building manager.
A parcel compartment is included with the models where that is provided. For apartments with many online deliveries this is a practical addition, but it remains a choice per project. Not every model within the WALL range has a parcel compartment as standard.
Installation is just as important as the model itself. The letterboxes must be accessible from the public road or a publicly accessible area, and the postal worker must be able to reach them without a detour. In an apartment building that often means a letterbox block in the entrance hall or on the facade, on a logical route.
Safety is an interplay of design and use. A sturdy aluminium housing helps, but no model is completely theft-proof. If you choose a combination lock, that applies to the models in which it is provided. For the WALL modular you align that per module.
Record the choices with the building manager and the architect: number of units, height, colour, material and any extras. This way you avoid discussion afterwards and the letterbox block remains consistent for years. The boxes are supplied by the manufacturer, and you make the agreements together with the building's manager.

There is no single fixed standard for all apartments. bpost provides guidelines on accessibility and operation, and for each building the property management and architect align the dimensions and layout. For a mailbox bank, it is best to choose a modular system such as the WALL, so that every residential unit gets its own, recognisable mailbox.
