It was slated for demolition, but now the charm of the Poortgebouw (gate house) is of great value to De Meelfabriek and it is even designated as a national monument. The old Poortgebouw has been restored and adapted for reuse.

The building dates back to 1940 and, like the adjacent Directiekantoor, is designed in a style influenced by Functional Expressionism by architect B. Buurman. It originally served as a bicycle storage and garage for executive cars.

In the rear section, storage spaces will be built for the residents of the Meelpakhuis, along with the necessary transformers. At the front, the contractors and construction staff will be temporarily located.
