VIERZIG549, Düsseldorf

Building 1.7 is part of the VIERZIG549 neighborhood in Düsseldorf's Heerdt district and, together with the adjacent buildings, forms the southwest entrance to the neighborhood on Willstätterstraße.

The design aims to combine residential, office, and commercial spaces within a single building, thereby promoting social diversity and a vibrant neighborhood structure. The plan includes office space, condominiums, and commercial units featuring restaurants and retail stores. From an urban planning perspective, a compact perimeter block with an inner courtyard is created, opening up to the neighborhood square while also offering semi-private open spaces for residents and users.

The building will be constructed as a hybrid timber structure with a wooden façade and a clearly defined base floor. Office and residential areas differ in their façade design but remain part of a unified ensemble.
In addition to an underground garage with parking spaces and bicycle storage rooms, green retention roofs, photovoltaics, and geothermal heating are planned. The goal is a sustainable building with DGNB Gold certification, Efficiency House 40 standard, and a high quality of life through the interplay of architecture, open space, and mixed-use development.
