In terms of its orientation, the building aligns with the neighbouring Church of St Anthony of Padua. The composition of differently articulated cubic volumes reflects the various functions housed within. The northern wing originally accommodated the administration of Prague’s transport company, while the southern wing, closer to the river, was occupied by the municipal utilities. The western porch, adjoining the church, once contained medical and spa facilities for employees.
The basement housed several halls as well as a cinema. The spacious central section is arranged like a passageway, from which the main staircase and the lifts - including paternosters - lead to the upper floors. From there, access is provided to the roof terraces, which were intended as recreational areas for staff, although it is unclear to what extent they were actually used for this purpose.
The two two-storey porches, extending like arms towards the central part of the building, lend the composition a particular elegance. The upper-floor windows are set without intermediate supports, enhancing the building’s strikingly modern character.
Inside, an air-conditioning system ensured that the building was heated in winter and cooled in summer, a notably advanced feature for its time.
