The building was designed in the style of new construction, erected on a steel frame. The front and rear facades have large areas of yellow-brown brick. These turned out to be stone strips during the 2007 restoration. The front façade has a strip of steel-framed windows on the left, which extends from the awning above the first floor to the roof. Behind that window corridor is a stairwell gallery. To the right of that on the center segment, from top to bottom, are the building's designation "CITY THEATER," an advertising screen for the films being shown, and a horizontal window section, all three executed in a vertical standing rectangle. To its right, a brick surface containing a small and a round window.
To its right, the stage tower made of brick begins at a height of 40 meters. From that tower hangs a circular staircase behind glass again in metal frames. On it was a crown, on which the name "CITY" was written four times. In addition, from the second floor to the roof, there are five strips of lights, closed by decorations. The last section of façade is angled to the building to match the building line of the adjacent building. The rear facade has an even larger area of brick.
The design was also progressive, in particular the tall and austere façade was a striking feature in the classic Amsterdam image of canal houses on the right and the City Theatre on the left. The imposing building volume was composed of two cubist elements. The facade plane was effectively broken by a long, narrow spiral staircase in a glass tower that was illuminated from within at night.
