The new commercial building at the Ostbahnhof station in Berlin boasts innovative and sustainable architecture that prioritizes both functionality and flexibility of interior use, ensuring high-quality design throughout.
320 meters long
The design of the building is divided into three segments, each approximately 320 meters in length. This approach breaks down the long and narrow site into more manageable and understandable parts.
To connect and divide the segments, the building incorporates large open and green atriums, which serve as natural gathering places and help to create a sense of community within the building. These atriums serve as the pulse of the building, providing spaces for people to meet and collaborate.

Sustainability
PLTFRM was designed with a focus on self-sufficiency, aiming to significantly reduce the amount of external energy required to operate the building. By utilizing innovative solutions such as recovering energy from a waste water duct through a heat exchanger and collaborating with the municipal water supplier, Berliner Wasserbetriebe, the building is able to heat and cool occupied areas with a heat pump. This reduces the amount of off-site energy needed by two thirds, resulting in just 34.5 kWh/sqm. Additionally, 20% of the building's electricity, equivalent to 10.5 kWh/sqm, will be locally generated through the use of solar panels installed on the roof and façade, covering a total area of 2830 m².
