The “Multi-Box”
Single Office Box
Phone Box
Conversation Box
Concentration Box
Confidentiality Box
Sound-absorbing box
The vision of a multifunctional office box was developed by consultants when implementing hybrid working environments
From this vision, the Multi Box was designed as a multifunctional space within the workplace and as a system component for hybrid working, user-centrically constructed and further developed to series production readiness.
Multifunctionality includes a wide range of uses such as use as a single office, for confidential conversations, two meetings, retreat & concentration, as well as the function as a sound-absorbing partition element in open spaces
The Multi Box is made exclusively from sustainable materials under “Cradle to Cradle” aspects
The box can be installed without technical preparation in all standard office spaces, both individually and in groups as a system
The external dimensions are not too large to allow the box to be integrated into all common office layouts without loss of efficiency, and not too small to ensure a high quality of stay inside as well.
A separate floor slab was omitted in order to give users a greater sense of space and better spatial integration
The Multi Box also allows access for people with limited mobility, such as wheelchair users, who can easily get into the box when the table is placed off-center.
Through an extensive “Test & Learn” program, minor errors and potential for improvement were identified, corrected and implemented


The Multi Box was designed for integration into open office concepts and offers a retreat space close to the workplace


The double door and sliding table allow use by two people with only minimal installation space


The highly sound-absorbing outer surface of the Multi Box reduces the reverberation time and thus improves the room acoustics


The Multi Box is the result of an iterative development process, the vision became reality step by step
Glass front with two glass doors and steel frames
Single or dual use without additional shunting space required

Walls and ceiling are highly sound-absorbing
Acoustically dampened inside for optimal conversation atmosphere
Outside, over 8 square meters of highly absorbent acoustic walls for improved acoustics in the room outside the box

The combination of “double door and sliding table” is new and has been patented accordingly
Conversation, concentration, confidence, …
With two seats and the table placed in the middle, the box can be used by two people for confidential conversations or participation in hybrid meetings, etc.

Single office, phone box, …
The table is attached to the back wall with a rail and can be moved with just one hand
With the table placed off-center, the box offers the user more space to move around and more comfort as a single office

Another unique feature of the Multi Box is its ability to be integrated as a piece of furniture into all common office concepts
Application example
The external dimensions of 2.25 x 1.21 meters are designed to allow the box to be integrated into all common office layouts
With these dimensions, the Multi Box is large enough to ensure a very high quality of stay even with two people
As shown in the illustration on the right, the box can be easily arranged at the head of a group of tables to provide employees with a multifunctional space that is very close to their workstation.
At the same time, the Multi Box is used as a sound absorber and protects the open workstations from office noise
The noises emanating from the open table group are also absorbed for the other office users

Another unique feature of the Multi Box is its ability to be integrated as a piece of furniture into all common office concepts

Glass elements: Two glass doors, 95.9 x 209.7 cm, made of 8 mm toughened safety glass (ESG), open outwards, and stop on the center beam. The glass doors are also available in laminated safety glass (VSG) for a version with increased sound insulation for an additional charge.
Wall elements: Acoustic system walls based on OSB/wood fiber, with a 9 mm vitAcoustic insulation panel made from recycled PET bottles (PET felt) on the inside and outside. Designed as a highly sound-absorbing system on the outside and an acoustically optimized system on the inside.
Ceiling elements: Acoustic system element like the walls, but highly sound-absorbing inside for deep absorption and coated white outside
Technical module: The electrical and ventilation systems are located on the ceiling element for acoustics. An integrated sound-absorbing labyrinth makes the ventilation system virtually silent.
Features: A duct on the rear wall provides both fresh air and power. All desired outlets, switches, screens, and even CO2 alarms can be installed here. The exhaust vent is located behind the dimmable LED ceiling light (at least 500 lux) and is therefore not visible. The power connection is via a 3-meter-long cable with a European plug.
Design: All PET felt surfaces can be selected from the 19 colors of the vitAcoustic color sample. The powder coating of the frames and frame components is also available in all standard RAL colors. The sliding table is available as a custom version in solid wood or as a standard version in chipboard with coated surfaces. The table can also be supplied by the respective furniture framework contract partner. Chairs, however, are not included in the scope of delivery.
Thanks to strong component partners, PrivateCubes is a startup with tradition, competence and highest performance
