Busch & Takasaki Architects Create Wood and Copper Sculpture in Hamburg

On Bramfelder Chaussee, where there was no clear address to mark the location of the Hamburg Energy Networks campus previously, the sculptural pavilion now makes a visible statement. The three-storey building is set back from the street and can be seen from afar. It serves as a reception area, exhibition space, and meeting place for employees and guests. Busch & Takasaki Architects were responsible for the design, while gmp Architects oversaw general planning and construction management. The aim was to create a building that provides orientation, signals openness, and expresses the company's values of innovation, sustainability, and energy through its architecture.

Designed as a vertical spatial sculpture, the pavilion is clearly distinguishable from the surrounding commercial and office buildings. Its various functions – reception, exhibition, meeting and break areas – are stacked compactly on top of each other and connected by an open staircase. Large glazed areas on the ground floor create transparency and link the interior and exterior spaces. Subtle projections in the facade direct the gaze and intuitively guide visitors to the entrance. Depending on the viewing angle, the building appears different: sometimes closed and monumental, and at others light and open – a clear yet changeable presence in the urban landscape.

The construction is based on a visible timber framework that forms the supporting and spatial structures. This creates a warm atmosphere, making it clear that sustainability is a design principle as well as a technical one. While the ground floor is fully glazed, the upper levels are clad with a copper facade. The vertical structure with standing seams and perforated elements creates depth and texture. During the day, the copper reflects the changing light, and at night, the building shines from within, creating a vibrant landmark on Bramfelder Chaussee.

The project follows a well-thought-out energy concept. A photovoltaic system on the roof supports electricity generation and heat is supplied via district heating. Underfloor heating ensures efficient operation. The ventilation system uses heat recovery. Active cooling has been dispensed with. The pavilion meets the highest accessibility requirements and is aiming for DGNB Gold certification. With its timber construction, use of recyclable materials, and avoidance of harmful substances, the building promotes responsible construction and establishes a new, distinctive presence for Hamburg's energy networks.
