Opening MUMUTH - Haus für Musik und Musiktheater, Graz


The MUMUTH - Haus für Musik und Musiktheater, a faculty building for the University of Music and Performing Arts Graz (KUG), has been ten years in the making, including two years of construction and will be officially opened on March 1st 2009. To celebrate this special event the Institute for Music Drama will present a performance of W.A. Mozart’s opera “The Magic Flute”, just before a “Celebration for Otto Kolleritsch”, Rector emeritus of KUG and a longstanding supporter of MUMUTH, will take place.

Since 1963 MUMUTH represents a central practice and event building for the KUG. “Finally we can offer our students an outstanding architectural building space to further their artistic training. The mission of the Arts University is the on-going development of the arts. Thanks to MUMUTH our audience can be increasingly involved in this exciting process”, says Rector KUG Georg Schulz.

The new Music Theatre, designed by Ben van Berkel of the renowned Dutch architecture firm UNStudio following an international competition with 212 entries, has already formed the Austrian contribution to the Venice Biennale of Architecture.

Of the design of MUMUTH Architect Ben van Berkel says: “The 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 the theatre and the themes that are at the basis of the building and its overall organization have also endured throughout this time.”

Construction of the 19 million euro new music theatre began in March 2006 and in August 2008 the Federal Real Estate Society (BIG) entrusted the main part of the building to the KUG. In February 2009 the MUMUTH also hosted part of the 7th International Competition “Franz Schubert and Modern Music”.

Upcoming events in MUMUTH include W.A. Mozart’s “The Magic Flute” (3rd, 5th and 7th March) and on April 2nd the new abo@MUMUTH starts with a staging of the “St. John Passion BWV 245”, the stage set for which has also been designed by Ben van Berkel/UNStudio (further performances: 4th, 6th and 8th of April).

1. Project text Music Theatre

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.

With the overt presence of the spring receding from the facade as the design evolved, the exterior again became a blank canvas, generating the opportunity to return to the theme of music in a new way. Our interest in re-establishing a relationship between music and architecture had from the beginning focused on shared aspects such as rhythm, continuity, channeling. Through our readings of the philosopher Gilles Deleuze we learned that there is another element that we had not seriously studied before: the element of repetition. Repetition generates an aggregate with densifications, intensifications and intervals. Repetition brings sonority. It allows for improvisation, it marks territory, it codes milieus. We decided to use a repetitive pattern, of our own design, and apply this to the facades in various ways to achieve some of these effects. The pattern, executed in the muted tones of stage make-up, is found all over the building in various degrees of density. Its appearance is furthermore impacted by changes in light during night and day, as well as by proximity and view angles since the outermost layer of the façade consists of a glittering mesh.

  • mike

    i like the idea of the inflated box.but the messy stuff in the middle is just ugly. Also un studios diagam’s stopped to make sense years ago (structure line…transparent section…).

  • i@n

    please post more sketches of projects-shows good insight into work.
    not sure about the structure and transport diagrams-look very simple

  • SouL

    loving the staircase…

  • Partick Bateman

    Excellent piece of architecture.

  • Josh

    I! WANT! DRAWINGS!!!!!!

  • When concrete is fully utilized as the fluid, morphic material it has always been, I smile.

  • rodger

    one has to ask, how is this technically possible to build these concrete curves so well? the construction method may be more interesting than the result but the result is remarkable enough.

  • boppie

    I like the ceiling around the staircase

  • tommi

    wooow, 10 yrs project, & do wanna see some drawings like sections~ from their projects, UNs seems d’ combination of OMA & HADID, not a bad thing ina way.

  • rodger,

    CNC molds!

  • homogenio exterior, interior with movement, and a very sculptural staircase, congratulations

  • Beautiful! An environment I’d want to be in, and often. Huzzah. I wonder how the acoustics are in such an asymmetrical space?

  • rodger

    thanks, i was assuming it would be something like that.

  • LOW

    I wanna make love to that staircase

  • A.R

    I have not seen much of these kindes of architecture as a built one. It shows the progressive and reality type of design !

  • A.J

    Who is Michael? Why must s/he comment on every post, and make snide remarks???

  • AJ,

    Why don’t you email me? Also, why don’t you define snide in that email? I believe the majority of my comments are critical, while the rest are complimentary. Why don’t you provide a counterpoint and make this a constructive discussion?

    I am a student of architecture working on getting a job as a designer. Ideally that would be with a firm that practices clean, smart design and upholds our mission of ethical integrity. I have enjoyed a lot of the responses on here, because I know they come from a diverse background. What say you?

  • medusa

    It is kind of interesting how several of UNstudio projects for theatres or concert halls are designed around a sculptural staircase. For all the plastic and spatial experimentation the end results are not too far away from Garnier’s Opera House. New shapes… old typologies…

  • jj

    Totally nonsense! And people really can write about anything or nothing! Truly amazing!

  • One

    Too feminin, really, curves, escaping from gravity,… weak,… romantic, …

  • yimyim

    sometimes i think …Yay for computer aided design and then othertimes i have to hang my head and wonder……..why?

  • togon

    are the concrete pre-cast or in-situ? wonder.

  • Archandy

    I actually like it. Firstly because it will perhaps silence those people who comment on such flowing designs by saying….”yes, nice renders, but you have no idea how to build it” Well. this one is built.
    Secondly, the space seems to work. I find it hard to believe that anyone walking into the space (first photo) will not look up and feel in awe of it. For me that is what Architecture is all about.

  • will

    the curved facade looks like a fisheye photo

  • Douglas Alford

    Having been a student of architecture for four years now and almost ready to graduate with my undergrad degree at a school that is primarily based on modernism. I myself being a one who questions all work at all times in order to progress design in all areas of the field of design. The more criticisms I receive the more I realize that most of it is purely subjective. I personally find this piece of work beautiful and very unpragmatic and the more that the better. I think most people are just scared of the future of architecture because they will not have a place in it when design has turned it’s cheek to pragmatism. It all has it’s place whether for to be compared to or to stand on it’s own as one of a kind. Just my two sense. Anyways beautiful piece of work. Wish there was more of it in the world.

  • Matt

    Spectacular building, in particular the interior. I just don’t think you could design something like this without a computer. Great use of this evolving tool. Much credit to the architects and maybe more to the builders. Interesting read too. Understanding thought processes without overdosing on BS is a good thing. Thanks

  • rachid

    nice staircaise….i like the interior spaces……nice project

  • T.

    I am less interested in the stair, although a fine detail, than I am the use of reinforced concrete in a manner that showcases it’s structural role as a both a compressive and tensile material, as well as its maleability as a material. Obviously structural in this instance, the concrete curves also inform the viewer of the material’s originally fluid state, much more so than had the space been supported by simple vertical concrete columns, of which I see none. I like structural rationalism, and in this case, find an interesting manifestation of it. Also, I have no idea what happens in the actual performance space, merely in the circulation space showcased here. What about the other 2/3 of the volume?

  • silicon m

    A conceptual reality manifest through solidified beauty.

    Wonderfully charming

  • gaque

    the interior is too hermetic…and the lighting quality doesnt help.
    i find the staircase rather kitsch. the bulge effect is interesting, but why?

  • Designed in 1998-03 and still it remains good looking and extremely ‘modern’.
    Its a some seriously slick design from UNstudio well done.

  • engineer

    The structure was build with SCC – Self Compacting Concrete in situ. Inside of the twist is a steel framework – surroundet by reinforcement.
    The boarding (if this is the right word) was made of claroporon (similar to styrofoam) cubes. The shape was cut with CNC an the cubes (2 * 2 *2 meter) where stacked like a magic cube. The interior was then filled with pumped in SCC. This was done in 3 sections, each about 6 meters high. The surface was not quite as beautifule after stripping, it needed some cosmetic work to looke like it does now.

    its very beutiful&wonderfull
