If you look at a photograph of the music theatre in Graz, Austria, you might think it had been taken with a fisheye lens, but the visual trickery is all in Dutch firm UN Studio鈥檚 design.

The 鈧�19m (拢17m) Haus f眉r Musik und Musiktheater opened on Sunday after two years of construction. It is a performance venue and faculty building for the local music and performing arts university, and incorporates a sense of movement and drama in its form.

Although it is a small structure, the bulge of its outermost mesh makes it appear as if it is bursting at the seams, and it has an impressive 6,200m2 floor area. The architect calls this a 鈥渂lob-to-box model鈥� and says it means the public entrance at the front of the building, and the rear door, through which the performers and students enter, are linked in an unbroken, flowing line.

On the first floor, a stainless steel staircase with a blood-red interior is the centrepiece for the area in which concert-goers will mingle between acts.

Unwinding from the building鈥檚 foyer is a coil of sculptured concrete that climbs and twists over the building鈥檚 three floors.

Ben van Berkel, UN Studio鈥檚 principal, said this 鈥渢wist鈥� was even more complicated to build than the similar structures in the practice鈥檚 RIBA award-winning Mercedes Benz museum in Stuttgart. He said: 鈥淭he 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.鈥�

Van Berkel and his co-principal Caroline Bos were recently awarded RIBA international fellowships. Their building subverts Goethe鈥檚 now clich茅d assertion that architecture is 鈥渇rozen music鈥�. This structure is music in flowing, effervescent form.
