About 3XN:

3XN has more than three decades of experience in designing and building innovative architecture, focused on humans. 3XN focuses on buildings that reflect and influence human behavior and the environment. The end result will be an innovative solution for complex contemporary challenges.

One of the most known projects created by the company is the Olympic House – the International Olympic Committee (IOC) headquarters in Lausanne (Switzerland). The company’s headquarters is in Copenhagen, but the company has offices in Stockholm, New York, and Sydney.

3XN also has an innovation unit specialized in a circular design, behavior design and digital design, named GXN. Their mission is to collect and apply the latest knowledge on materials, sustainability, behavior, and new technologies to the studio’s architecture.

Thoughtful, Sculptural Design

Cube Berlin is designed to be a catalyst for social experiences – both inside and out. Therefore, the design aims to engage in a dialogue with the site’s busy square and to animate the prominent urban location. All four facades support interaction between the building occupants and the surrounding environment. The aim was to deliberately create a subtle boundary between indoor and outdoor spaces.

Cube Berlin also reinterprets the idea of the cube, due to reflective glazing that mirrors both the adjacent nature and skyline. 3XN has created deliberate geometric transformations that create a prismatic pattern of triangular surface reliefs, while the defining geometry of the structure maintains a true cubical volume measuring 42.5 meters in all directions.

Segments of the façade are pushed inward in order to create outdoor terraces at all levels. The roof is envisioned as a “fifth façade” and completes the concept of the cube. A vast rooftop terrace serves as a common space for tenants and can be used as a breakout or event space. Surrounding Berlin landmarks are reflected in all angles of the façade, allowing this landmark structure to shed a dynamic new light on its surroundings, both day and night.

Flexible office layouts

Inside, Cube Berlin is designed to cater to future demands for flexible office layouts and can accommodate shifting structural needs. The floors are arranged around a central core and can be divided into a mixture of separate units or connected via internal atria. 3XN’s design encourages communication and social activity through dynamic workplace constellations available in a wide range of sizes.

Digital Cube Berlin

Digital “Brain” Cube Berlin is a next-generation smart building that sets new standards for the integration of intelligent digital user interfaces. Users are invited to interact with the building through a “bring your own device” approach. This is achieved via an app that drives sustainable behavior and increases energy efficiency while reducing unnecessary operational costs and maintenance irregularities. In this way, users can interact with their workspaces in unprecedented ways. Smart features allow tenants to customize and control such features as access control, indoor heating and cooling, maintenance, energy supply, room and parking reservations, charging of electric cars/bicycles, and more.

The digital brain server connects the intelligent systems of Cube Berlin

Building operational information is stored in a large “digital brain” server that connects the individual intelligent systems of cube berlin. Energy flow and consumption are monitored and maximized, resulting in a building that is both self-learning and highly efficient. In this way, the building and its users enter into an interplay where both are learning from each other. The building learns to adjust to the preferences of its users, while the users can control and adapt the building’s settings according to their desires and needs.

Energy Efficient Glazed Façade Contrary to conventional wisdom, the fully glazed façade of cube berlin is highly energy efficient due to its osmotic skin and thoughtful design that includes a pioneering application of solar coatings on the outer skin of the double façade. This, in addition to a suite of technical solutions that include energy capture from heat, allows Cube Berlin to perform as a highly energy effective fully glazed building.
Architecturally, the technical performance of the material allows for energy performance and control that will allow the building to pursue a DNGB Gold certification while Cube Berlin’s fully glazed façade provides a dramatic commentary on the Berlin cityscape.
