The brick building at Gravenstraat #3 is 5 bays wide and 3 deep. It has two floors and on top of that a wooden superstructure on a square base. That superstructure does not match with the rest of the building, that looks rather unbalanced because of this.
The whole front is covered by a gallery two floors high with Doric pillars and protruding entrance steps at the sides. The main door is lavishly framed and topped with a semi-oval top light with radiating panes. The ground floor is fitted with marble tiles.
