This building was originally used as a brewery and its owners retained an industrial character with the huge black windows. Its huge spaces do not miss the spaciousness, so everything has a great place.
The huge velvet sofa and the dining area are my favorite, but I would totally not refuse the apartment if it could be mine! :)
Here's an airy studio feeling that has been preserved and reinforced. Decorative arches have been added - so-called slits - and run along the ceiling. A really nice solution that enhances the feeling of height and space.
The smoked glass glass table is vintage.

The ceiling lamp is a real design classic called Sputnik. Find similar at Wayfair.
The kitchen is complete with a dining area consisting of classic Y-chairs by Hans J. Wegner, a black table and bench.
The huge factory windows are found in all the rooms that face the Igeldamm street and the courtyard.
