New rooms in open spaces

Thinking retreat, conference room, quiet zone: Kubus I and Kubus II from Strähle create new rooms in open spaces. Our room-in-room solutions enrich modern, open office concepts with high-grade retreat areas. As they can be freely positioned in the space, they enable efficient use of space without detracting from the transparency. The Kubus models do not need to be connected to any part of the building such as the façade, the wall or the ceiling. They can be flexibly configured, are highly sound-insulated and extremely functional. As an option, the room systems can also be equipped with a self-contained electrical cooling unit as a plug & play solution, independent of the existing technology used in the building.

Kubus I - Room-in-room-system with single glazing

The all-glass Kubus imports transparent retreat areas into large office spaces. The elegant aluminium structure of Kubus I with its all-glass design flush to the outside fits smoothly into the existing architecture.


In addition to the quality of the design, the Kubus models offer excellent sound insulation. Even in the single-glazed version, sound level differences of up to 34 dB have been achieved.

Always well ventilated

The standard version of the Kubus is equipped with a ventilation and an air extraction device with an output of 210 m³/h to ensure a supply of fresh air. This can be easily controlled via a multifunction touch display. As an option, the room system can be supplemented with a self-contained electrical cooling unit.

Room-in-room system with double glazing

The Kubus II room-in-room system meets the highest standards of aesthetics and functionality. The reduced design with filigree visible widths and flush-fit glazing on the outside enable easy integration into a range of different office space concepts. Excellent sound insulation values thanks to double glazing ensure a working environment for high concentration. Kubus II Plus was awarded the Architecture + Office innovation prize thanks to its perfect combination of design, functionality, quality and technology.

In the thick of things in peace and quiet.

In the middle of the day-to-day hustle and bustle of the office, the highly sound-insulated Kubus II stands in the open space like an island. Noises from and to the exterior are shielded. Here, sensitive topics can be discussed in confidence. Low reverberation times over the whole frequency range increase the comfort and guarantee a pleasant environment for discussions and meetings.

Variants for pleasant interior climate

Kubus II: ventilation

The standard version has a sound-insulated ventilation system which can be easily controlled via a multifunction touch display.

Kubus II C: ventilation + cooling

Kubus II C is additionally equipped with a steplessly adjustable cooling convector built into the sideboard and connected to the cold water network on the building side using a flow/return of 16°/18°C respectively.

Kubus II Plus: ventilation + self-contained cooling

Plug in and keep cool. The cooling convector integrated into the sideboard is supplied with cold water from an independent cooling unit on the roof. This makes Kubus II Plus the self-contained plug and play solution. This version is ideal for revitalising existing offices or for rented space because no alteration to the building infrastructure is necessary.
