Invisible Houses – Workshops of the Institute for Deaf-Mute Youth
At the beginning of the 1960s, the Institute for Deaf-Mute Youth needed premises to train students in various printing tasks requiring large areas of free space. With the Workshops, built in 1963, the architect Savin Sever developed the themes that characterise his entire oeuvre. He later refined and adapted these concepts to different materials and functions (e.g. similar skylights, albeit modified, were used at the Mladinska knjiga Printing House, the Merkur store and the Astra department store).
The building was located on Bežigrajska Street and was part of the broader planned Bežigrad neighbourhood centre, which was never fully realised. It was related in design to the nearby Astra complex, which follows the basic urban scheme of Dunajska Street. The construction of the building began in autumn 1962 and was completed in summer 1963, i.e. in less than a year, which was made possible by a predominantly prefabricated construction, prefabricated façade elements and serial furniture. The materials used were new and inexpensive at the time (asbestos-cement pannels), and the design of the building from the beginning provided for the simple replacement of the façade infills as they deteriorated.
The design of the building is a simple orthogonal multi-level floor plan with sides of 34 and 43 metres, on two floors. The basement was constructed in reinforced concrete, with columns set 4,8 metres apart. The ground floor structure was a concrete frame, the vertical load-bearing elements being columns set 7,2 metres apart. The roof was made of prefabricated panels and the cornice caps of specially manufactured asbestos-cement elements.
Taking into account the functional requirements of print production, Sever designed the interior in longitudinal programmatic strips. The central part was a hall with a visible ceiling structure spanning 15 metres and with intermediate skylights running longitudinally along the entire length of the space. Above the main printing hall was a raised roof and basilica-type windows. The lighting was therefore masterfully designed as a combination of zenithal, basilica-type and horizontal lighting. This space was followed by two more longitudinal strips: the offices, separated by lightweight prefabricated partitions, and an intermediate service area. The author also designed the interior furnishings, such as the built-in wooden cupboards. The functionality of the building was reflected in the combination of a large open area and smaller spaces, which allowed for diverse use of the space.
The façade consisted of prefabricated wooden elements, covered on the outside with aluminium sheeting or asbestos-cement elements. The alternation of the different types of façade elements (window and wall) was adapted to the needs of the programme in the building, and these elements also served the functions of closing, illuminating and ventilation. These windows were the basis for the design of the more complex window openings on the Astra and Commerce high-rise buildings. On the façade, we can observe the classical vertical division into a cornice above, a façade section and a basement section, which the architect used again later (e.g. for the Mladinska knjiga Printing House). The rhythmic alternation of the façade elements and the accentuated entrances, which stood out from the mass with their canopies and steps, gave the building its artistic expression. This is not new, as the paraphrasing of classical architectural elements (rhythm, vertical division into cornice, façade and basement zone, etc.) using a multiplied façade element has been seen in the past, in the design of 19th century industrial architecture.
The qualities of this building were its rapid and cost-effective construction (using a combination of prefabricated reinforced concrete skeleton and prefabricated elements) and its adaptability to the needs of the activity. The prefabricated architectural elements were no longer an inferior construction element.With this building, the architect began his journey as a designer of thoughtful, refined architecture with originally conceived details. Originally designed windows and skylights, as well as the rhythmical alteration of façade elements, can be seen in most of Sever’s later buildings, as it was the repetition of façade elements and the structuring of the building envelope that became one of the most prominent characteristics of his buildings.
After production ceased, the building was in a very poor state of repair for a long time due to lack of maintenance, and there were repeated calls for its removal. At the same time, demands for the Workshops to be classified as a listed building, based on an assessment of its quality, have become increasingly vocal, both in the context of the artist’s oeuvre and within the history of the architectural heritage of the 1960s.
In March 2000, the Workshops building was demolished to make way for a new building, but decades later, nothing has happened on the site.
The presentation of The Workshops of the Institute for Deaf-Mute Youth is part of the project Invisible Houses.
