The architects EM2N transformed the former Toni Dairy (built in the seventies) into a University campus for 5000 students, lecturers, and employees. The industrial character of the interior, the raw and direct materialization in the interiors, creates one open framework for students and lecturers. 

Annette Douglas convinced the jury with her textile concept and was commissioned with the design, development, planning, budgeting, and overviewing of the production of all textiles in the building. 

The architects play with different degrees of refinement, mostly raw and sometimes also refined or colorful. The textile concept goes along with the concept of the architects, sometimes ponderous, robust, and grainy. The «pearl» rooms are more detailed and refined like the big concert hall.

Annette Douglas has developed an acoustic concert curtain, a masterpiece for the big concert hall. The acoustic curtain is a mobile acoustic element and part of the overall acoustics in the concert hall. The catalog of requirements for the curtain by the planners was very ambitious. Like the defined acoustic flow resistance, a defined absorption coefficient over the individual frequencies (Hz), and fire protection requirements for a hall with large occupancy. Additionally, the tightly dimensioned parking options in the concert hall, allowed only an addition of 30% folding of the curtain. All these factors made the starting point very complex. Annette Douglas developed a trompe l'oeil design for the curtain. The folding or waves of the curtain are embroidered as wavy lines.

The acoustic measurements have shown that the performance of the curtain corresponds exactly to the modeling. In addition, all fire protection requirements were fulfilled to 100%.
