The relationship between music and architecture is a classical one. Too classical for our times, may be the thought of many contemporary architects. But that is not our view; UNStudio likes classical with a twist… The theme of the acoustic space, explored for its dramatic potential by Le Corbusier and Xenakis is still to us a topic of fascination and incredible potential today. And since the MUMUTH theatre belongs to the University of Music and Performing Arts Graz and is therefore a place where young musicians receive their instruction in the performing and musical arts, it seems to us even more appropriate to let the architecture communicate that this is a building in which music lives.
This desire to make a building that is as much about music as a building can be, has been a constant throughout the nearly ten years that it took to build it. Although the project outwardly has changed considerably since its inception, the two themes that are at the basis of the building and its overall organization have endured.
The first of these two themes is the so-called ‘spring structure’ which bears the most direct relationship to music. In the first stage of the competition, the design was still very conceptual and was envisaged as an elongated spring of varying diameter size, which would alternately be stretched, suppressed and folded up inside itself to offer structure to the various volumes that together make up the theatrical, audience, rehearsal and utility spaces. We saw the spiral as the organising element of the MUMUTH in much the same way as Serialism works in contemporary music; the continuous line absorbs and regulates intervals and interruptions, changes of direction and leaps of scale without losing its continuity. Things hang on this line like laundry: glass, concrete and installations. In many ways this principle still holds, although in the building as it stands today the coil motif is no longer prominently displayed on the facades, as it was in that first conceptual design, but is now invisibly absorbed in the construction.
In fact, the legibility of the spring was dissolved only gradually. The design that was made for the second stage of the competition shows a refined spiral concept, which, like an octopus, is simple, orthogonal and horizontally orientated on one side and turns into a complex, smaller-scaled principle on the opposite side. This principle of a spiral that divides itself into a number of interconnected smaller spirals that take on a vertical and diagonal direction became an important design model for us which we called the blob-to-box model. It illustrated in a simple line diagram how a building could be structured to combine within one, rigorous gesture a strict, unit-based volume (the black box of the theatre) and a series of flowing, movement-based volumes (foyer and public circulation). Because this organising principle is made constructive, a free, fluent internal spatial arrangement is actualised, efficiently connecting spaces to each other. And, like the spring structure, the blob-to-box motif also remains a core principle of the final building. The theatre has a public character which is dynamic and which facilitates groups of people moving through it during events, and it has a calm, quiet, intense, but also very flexible and rational character which is related to the specific prescriptions of the auditorium and the rehearsal studios.
The unit-based part of the organization (the box) is situated on the right side and the movement-based part (the blob) on the left side of the building as seen from the Lichtenfelsgasse. There are two entrances; the everyday entrance on the park side which is used by students and staff, and the public entrance on the Lichtenfelsgasse which is used by the audience when there is a performance. On performance nights, the student entrance is transformed into a wardrobe using mobile closets. A removable ticketing desk and screen bulletin are placed underneath the staircase. The public ascends a wide staircase and enters a large foyer on the first floor. This foyer gives access to the multipurpose auditorium that can seat up to 450, and that is adaptable to a great variety of performances, ranging from solo instruments to opera to full orchestra.
The free-flowing space of the foyer is made possible by a spiraling constructive element that connects the entrance to the auditorium and to the music rooms above, thus welding together ‘with a twist’ the three levels of this side of the building. The twist is in fact a massive concrete construction which was one of the most challenging we ever realized – more difficult to achieve even than the twists in our recently completed museum for Mercedes-Benz. The dimensions of this particular twist necessitated far greater precision and the use of self compacting concrete which was pumped up from below instead of poured down from above as is the usual method. The twist forms a central feature of the public space, around which everything revolves. Lighting and material details accentuate the ripple effect. The twist is highlighted from above by a skylight in the ceiling, which itself consists of lamellas executed in dark wood which fan out from the twist in a wave-like pattern.
