New Office Building for 3D Composite GmbH

Harmony of Space, Light, and Acoustics.

The Objective
As part of expansion efforts, a new production facility was built at 3D Composite in early 2026. In addition, an office area of approximately 200 m² was created, featuring modern workstations and a spacious conference room, with the aim of bringing organizational and production-related activities closer together spatially while simultaneously creating a contemporary work environment. Particular emphasis was placed on achieving balanced room acoustics. In the office area, the goal was specifically to reduce reverberation and thereby create a quiet atmosphere conducive to focused work. Large window areas and the existing concrete surfaces acted as acoustically hard surfaces. Through the strategic use of Selador acoustic elements, these surfaces were both acoustically optimized and integrated into the interior design concept. In the spacious conference room, on the other hand, the emphasis was on clear and consistent speech intelligibility—even over greater distances.
Our Approach
Thanks to our existing collaboration with 3D Composite, we were already familiar with Selador products from previous projects. Acoustic planning was therefore integrated into the design of the new office space at an early stage. Even during the planning phase, the existing grid ceilings were taken into account as part of the acoustic concept. Acoustic software was used to determine the equipment needed to achieve balanced and natural room acoustics. Based on this, we provided consultation on the arrangement and design of the acoustic elements in the individual areas. Since the integration of lighting was also considered in parallel with the acoustic planning, both aspects could be coordinated from the very beginning. This resulted in a holistic concept in which acoustics, lighting, and interior design are seamlessly integrated.

The Result
The result is a modern and inviting work environment with balanced room acoustics. The targeted reduction of reverberation creates a quiet atmosphere in the office areas, conducive to focused work. In the conference room, the optimized acoustics ensure clear and consistent speech intelligibility.
