SIEBENNEUN – The future of work with a sleek, light-filled floor plan that creates a penthouse feel on every floor.

The build­ing at Königsstraße 7–9 presents itself as a contem­por­ary reinter­pret­a­tion of classic metro­pol­itan archi­tec­ture. With its clean façade design and vertic­ally emphas­ised window axes, it blends harmo­ni­ously into DĂŒsseldorf’s historic city skyline without resort­ing to nostal­gic refer­ences.

Architectural language

The façade is charac­ter­ised by a minim­al­ist design language that conveys both auster­ity and elegance. Generous window areas lend a sense of rhythm to the storeys and create a bright, open effect. Subtle cornices and continu­ous string courses emphas­ise the horizontal lines, whilst the building’s bevelled corners open up the urban space and lend the struc­ture a stately presence facing the street. The vertical struc­ture is emphas­ised by the clear, repet­it­ive arrange­ment of the windows, which lends the façade a classical tectonic quality. At the same time, the integ­ra­tion of green elements into the façade bands breaks up the auster­ity and adds a distinct­ive touch in keeping with the principles of sustain­able urban archi­tec­ture.

Roof Design & Impact on the urban fabric

The stepped attic, with its mansard-style design, forms the upper crown of the build­ing. It draws on the tradi­tion of metro­pol­itan rooftops, yet inter­prets it in a contem­por­ary, minim­al­ist design language. A notable detail is the central segmental-arch window, which emphas­ises the building’s vertical axis and provides it with a strik­ing crown­ing feature.

Thanks to its corner location, the build­ing becomes a key focal point within the urban fabric. The rounded corner at ground floor level invites people to pass by and linger, helping to bring the street space to life. In dialogue with the adjacent street spaces, the build­ing marks a tranquil yet self-assured intro­duc­tion.
